The first case of accidental implantation of ovarian tissue at the port site after laparoscopic ovariectomy in a cat was described. A 2-year-old, spayed female, domestic cat showed recurrent behavioral oestrus signs (vocalization, increased playfulness, and lordosis) four months after laparoscopic ovariectomy. Abdominal ultrasound revealed bilateral endometrial hyperplasia and an inhomogeneous mass attached to the abdominal wall at the port site of previous laparoscopic ovariectomy. Ovarian remnant syndrome was supposed. Diagnostic laparoscopy confirmed the presence of a mass that was 2 cm in diameter and macroscopically similar to ovarian tissue. Laparoscopy was converted to laparotomy to remove the abnormal tissue and the uterus. Histopathological findings showed follicles of various maturation stages in the mass, and confirmed endometrial hyperplasia. Histology underscored that ovarian remnant tissue resumed function. No clinical signs consistent with ovarian remnant syndrome were reported six months after removal of the abnormal tissue. In conclusion, removal of the ovaries through the laparoscopic port site may cause fortuitous ovarian tissue implantation at the abdominal wall in the cat.

Case summary A 9-year-old male neutered domestic shorthair cat was presented with a 2 day history of anorexia and vomiting. A minimum database, including a complete blood count, serum biochemistry profile and urinalysis were unremarkable apart from a toxic neutrophilic left shift and borderline proteinuria. Abdominal ultrasound revealed intramural gas entrapment with thinning of the gastric wall, a hypoechoic pancreas, peritoneal fluid and a small volume of peritoneal gas along with a hyperechoic mesentery. CT was performed and demonstrated gas within the gastric submucosa and gas in the peritoneal cavity. Generalised gastric erythema was present at surgery and histopathology of excised abnormal areas reported gastric erosion with no obvious causative agents; however, pretreatment with dexamethasone may have been a contributing factor. Culture from biopsied gastric tissue was sterile. Clinical signs resolved after partial gastrectomy and medical management. Relevance and novel information Feline gastric pneumatosis is a rare clinical finding. Imaging is essential for diagnosis and to decide on the appropriate treatment; this is often medical but in cases where there is suspicion or evidence of gastric perforation, surgery is indicated. To our knowledge, this is the first case of feline gastric pneumatosis secondary to gastric ulceration, diagnosed via CT and where dexamethasone may have been a contributing factor.

Number Of Patients

The "port-site metastasis" represents a tumor recurrence that develops in the abdominal wall within the scar tissue of the insertion site of one or more trocars, after laparoscopic surgery, not associated with peritoneal carcinomatosis. This last aspect is central because in the literature some isolated cases are reported, but most cases are associated with peritoneal carcinomatosis. The first case in the literature dates back to 1978 and in the literature, the incidence varies from 1% to 21%, although most published research reports a very small number of patients. Currently, the incidence in a specialized cancer center is consistent with the incidence of recurrence on a laparotomy scar. Possible mechanisms for cell implantation at the port site are direct implantation into the wound during forced, unprotected tissue retrieval or from contaminated instruments during tumor dissection; the effect of gas turbulence in lengthy laparoscopic procedures, and embolization of exfoliated cells during tumor dissection or hematogenous spread. Probably, however, the triggering mechanism is necessarily multifactorial. To date, the only significant prognostic factor in patients diagnosed with port-site metastasis is the interval between laparoscopy and the diagnosis of the port site: in fact, patients who develop the port site within 7 months after surgery have a generally worse prognosis, as well as port-site metastasis are more frequent in advanced cancers and the presence of ascites. To reduce the risk, the following measures are proposed in the literature: 1) Select the patient who does not have a metastatic oncologic condition or friable cancerous masses or lymph node spread or attached external or intracystic vegetations, preferring well-localized, benign or low-malignant or otherwise intact tumors; 2) Use wound protectors and use of protective bags (or endo bag) for tissue retrieval; 3) Peritoneal washing with heparin, to prevent free cell adhesion, or washing with cytocidal solutions. Evaluate the utility of using Povidone-iodine, Taurolidine (which has anti-adhesion activity and decreases proangiogenic factors), and chemotherapy products; 4) Avoid removing pneumoperitoneum with trocars in place; 5) Avoiding direct contact between the solid tumor and the port site; 6) Prefer laparoscopy to laparotomy, if possible; 7) Avoid the use of gas or direct CO2 insufflation, although in literature the point is controversial and deserves more attention and study, as the initial hypothesis that CO2 increased the invasion capacity of tumor cells (in vitro and in vivo) has been refuted several times. Insufflation of hyperthermic CO2 and humidified CO2 leads to a better outcome in patients with a malignant tumor who undergo a laparoscopic procedure compared with normal CO2 pneumoperitoneum; 8) Comply with surgical protocols and techniques by updating one's surgical skills, as it has been demonstrated, as already reported here, the presence of cancerous cells on instruments, washing systems and trocars (in particular, on the trocars of the first operator). Suturing all layers of the abdominal wall decreases the risk of the port site; 9) Avoid excessive manipulation of the tumor mass during the surgical/operative procedure.

Case summary A 16-year-old domestic shorthair cat was evaluated for acute-onset right pelvic limb monoparesis localized to the sciatic nerve. MRI revealed a homogeneously contrast-enhancing, well-demarcated mass effacing the right sciatic nerve from its intravertebral origin to the end of the viewable field (mid-femur). Abdominal ultrasound revealed thickened small intestinal loops and enlarged mesenteric lymph nodes. Cytology of the small intestine was suggestive of lymphosarcoma. T-cell lymphosarcoma of the sciatic nerve and small intestines was confirmed with incisional biopsy. Treatment consisted of systemic chemotherapy with vincristine followed by the Wisconsin–Madison feline lymphosarcoma protocol, but despite treatment the patient neurologically worsened and was euthanized after 54 days. Relevance and novel information We present herein one of the first descriptions of neurolymphomatosis in the domestic cat that included post-intravenous contrast MRI. Treatment options based on recommendations for people with neurolymphomatosis include systemic chemotherapy, intrathecal chemotherapy and/or localized radiation chemotherapy. The authors recommend that all cats be screened for concurrent non-neuronal areas of lymphosarcoma before undergoing treatment for neurolymphomatosis, regardless of clinical signs.

Desmoid tumors (also called desmoids fibromatosis) are rare slow growing benign and musculoaponeurotic tumors. Although these tumors have a propensity to invade surrounding tissues, they are not malignant. These tumors are associated with women of fertile age, especially during and after pregnancy. We report a young female patient with a giant desmoid tumor of the anterior abdominal wall who underwent primary resection. The patient had no history of an earlier abdominal surgery. Preoperative evaluation included abdominal ultrasound, computed tomography, and magnetic resonance imaging. The histology revealed a desmoid tumor. Primary surgical resection with immediate reconstruction of abdominal defect is the best management of this rarity. To the best of our knowledge and PubMed search, this is the first case ever reported in the medical literature of such a giant desmoid tumor arising from anterior abdominal wall weighing 6.5 kg treated surgically with successful outcome.

Domestic shorthair 10-year-old cat, not sterilized, not vaccinated, feeding from the table. We went to the clinic with breast cancer. General and special research methods were performed: blood analysis, x-ray examination of the lungs and abdominal ultrasound. Based on anamnesis and clinical examination, the diagnosis was made: a malignant breast tumor. The operation was performed. The operating material is sent for histological examination. Chemotherapy was prescribed. After the fi rst chemotherapy and monitoring of the animal's condition, it was necessary to perform a second unilateral mastoectomy of the remaining mammary glands, but the animal's owners refused to perform the operation. Chemotherapy was performed twice. Re-applied, after a year and a half with a sharp deterioration in the General condition and the appearance of a new tumor on the non-removed mammary glands. The owners refused the necessary treatment and decided to euthanize the cat. At the autopsy, breast neoplasms are presented as tubercles of various sizes. There are pronounced signs of inflammation, ulceration and necrosis foci. In the chest cavity, the lungs are enlarged, there were single and multiple formations of white and brown color, round shape of different diameters, dense consistency. There is a large number of metastases in the liver parenchyma. The organ is enlarged in size, dark brown in color, irregularly colored, with an uneven (bumpy) surface. In General, there are many dense nodes of a round-oval shape of white color, of various diameters. Histological examination of the tumor revealed foci of necrosis, atypical glandular complexes with frequently occurring mitosis figures. This structure indicates a low-grade breast adenocarcinoma. In the lungs, there is an expansion of the alveoli and bronchioles, thinning and rupture of the interalveolar partitions. There is a complex of tumor cells. In the liver, there is a lack of structural units of the liver, hepatocytes disperse chaotically, liver triads do not have a clear localization, atrophy and necrosis are expressed. Metastases in the liver, various forms. In a cat, a breast tumor interpreted as an adenocarcinoma had different biological behavior. At the initial diagnosis-adenocarcinoma of medium differentiation, and a year and a half later-low-grade adenocarcinoma.

A 23-year-old pregnant warmblood mare from Güssing, Eastern Austria, presented with apathy, anemia, fever, tachycardia and tachypnoea, and a severely elevated serum amyloid A concentration. The horse had a poor body condition and showed thoracic and pericardial effusions, and later dependent edema and icteric mucous membranes. Blood smear and molecular analyses revealed an infection with Theileria equi. Upon treatment with imidocarb diproprionate, the mare improved clinically, parasites were undetectable in blood smears, and 19 days after hospitalization the horse was discharged from hospital. However, 89 days after first hospitalization, the mare again presented to the hospital with an abortion, and the spleen of the aborted fetus was also PCR-positive for T. equi. On the pasture, where the horse had grazed, different developmental stages of Dermacentor reticulatus ticks were collected and subjected to PCR, and one engorged specimen was positive for T. equi. All three amplicon sequences were identical (T. equi genotype E). It is suspected that T. equi may repeatedly be transmitted in the area where the infected mare had grazed, and it could be shown that transmission to the fetus had occurred. Due to the chronic nature of equine theileriosis and the possible health implications of infection, it is advised to include this disease in the panel of differential diagnoses in horses with relevant clinical signs, including horses without travel disease, and to be aware of iatrogenic transmission from inapparent carrier animals.

Abstract Background Encapsulating peritoneal sclerosis is a rare but potentially lethal complication of long-term peritoneal dialysis that is associated with significant morbidity and mortality. The occurrence of encapsulating peritoneal sclerosis varies worldwide, but is increased in patients maintained on peritoneal dialysis for 5–8 years. The etiology of encapsulating peritoneal sclerosis remains unidentified, and a high index of clinical suspicion is required for diagnosis. Case presentation We report a 5-year-old Saudi female with end-stage renal disease secondary to nephronophthisis type 2. She underwent peritoneal dialysis for 30 months, with four episodes of peritonitis. She presented with clinical signs of peritonitis. Three days later, she developed septic shock, which required pediatric intensive care unit admission. The peritoneal dialysis catheter was removed because of refractory peritonitis. Her course was complicated by small bowel perforation, and severe adhesions were revealed on abdominal ultrasound and computed tomography, consistent with a diagnosis of EPS. This finding was later confirmed by diagnostic laparotomy performed twice and complicated by recurrent abdominal wall fistula. She received total parenteral nutrition for 6 months and several courses of antibiotics. The patient received supportive treatment including nutritional optimization and treatment for infection. No other treatments, such as immunosuppression, were administered to avoid risk of infection. Following a complicated hospital course, the patient restarted oral intake after 6 months of total parenteral nutrition dependency. Her abdominal fistula resolved completely, and she was maintained on hemodialysis for few years before she received a kidney transplant. Conclusion When treating patients using peritoneal dialysis, it is important to consider encapsulating peritoneal sclerosis with refractory peritonitis, which is not always easy to identify, particularly if the patient has been maintained on peritoneal dialysis for less than 3 years. Early identification of encapsulating peritoneal sclerosis and appropriate conservative treatment, including nutritional optimization and treatment of infections, are essential to achieve a better prognosis.

Histologic examination was performed on uterine biopsy samples of irregular cystic masses noted during caesarean section of a 2-year-old female Boer goat. Histopathologic examination revealed multifocal erosions of the superficial epithelium and multifocal infiltration of the endometrium by widely scattered viable and degenerate neutrophils, lymphocytes, and plasma cells admixed with mild amounts of cellular debris and hemorrhage. The endometrium was markedly expanded by many irregular cystic and hyperplastic glands. This is the first case report of endometritis and cystic endometrial hyperplasia in a goat in North America.

Objectives The aim of the study was to evaluate ultrasonographic changes in the small intestine of cats with clinical signs of gastrointestinal disease and low or low–normal serum cobalamin concentrations. Methods Records for client-owned cats presenting to the small animal hospital with signs of gastrointestinal disease and in which serum cobalamin concentrations were measured from 2000–2013 were reviewed. Inclusion criteria were cobalamin concentrations <500 ng/l, abdominal ultrasound within 1 month of cobalamin testing and definitive diagnosis. Results Of 751 serum cobalamin measurements, hypocobalaminemia or low–normal cobalamin was identified in 270 cats, abdominal ultrasound was performed in 207 of those cats and a diagnosis was available for 75 of them. Small intestinal ultrasound changes were detected in 49/75 (65%) cats. Abnormalities included thickening, loss of wall layer definition, echogenicity alterations and discrete masses. Serum cobalamin concentrations <500 ng/l were observed with diagnoses of inflammatory disease, neoplasia, infectious disease and normal histopathology. Cobalamin concentration was significantly lower in cats with lymphoma or inflammatory bowel disease compared with other gastrointestinal neoplasia ( P = 0.031). No difference was found between cobalamin concentration and the presence of ultrasound abnormalities, specific ultrasound changes or albumin concentration. Conclusions and relevance One-third of symptomatic cats with hypocobalaminemia or low–normal cobalamin concentrations may have an ultrasonographically normal small intestine. For the majority of cats in this study, histopathologic abnormalities were observed in the small intestine, regardless of ultrasound changes. These findings suggest gastrointestinal disease should not be excluded based on low–normal cobalamin concentrations, even with a concurrent normal ultrasound examination. Additional studies are needed in cats with low–normal serum cobalamin concentrations, as a definitive diagnosis was not pursued consistently in those cats. However, data from this study suggest that careful monitoring, histopathologic evaluation and future cobalamin supplementation may be warranted.

Case summary This paper presents two cases of acute postoperative upper airway obstruction following ventral bulla osteotomy (VBO) in cats. The first cat underwent a unilateral left-sided VBO for a suspected inflammatory polyp. The second cat underwent a single-session bilateral VBO procedure for bilateral otitis media. In the first case, immediate re-intubation and a gradual lightening of the anaesthetic plane resolved the clinical signs; in the second case, the patient deteriorated and went into acute cardiorespiratory arrest and received cardiopulmonary resuscitation. Both patients recovered well and were discharged home 3 days after surgery. Both cases were reported to show no further clinical signs on postoperative follow-up 3 weeks and 4 months after surgery, respectively. Relevance and novel information Upper airway obstruction should be regarded as a potential complication of VBO in cats.
