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.

Case summary A 6-year-old female spayed Ragdoll presented with a 4-day history of acute onset non-productive retching, coughing and anorexia. A complete blood count, serum biochemistry, thoracic radiography and abdominal ultrasound were performed. Initially, aspiration pneumonia was suspected owing to an alveolar lung pattern in the right cranial ventral lung lobes seen on radiographs. The cat did not improve with empirical antibiotic therapy. Bronchoscopy and bronchoalveolar lavage were performed. An intraluminal tracheal mass was identified and removed via endoscopic guidance and gentle traction. Histopathology results were consistent with a fibrinous tracheal pseudomembrane. The cat was concurrently diagnosed with Pseudomonas aeruginosa pneumonia, which was confirmed on bronchoalveolar lavage. Pseudomonas aeruginosa was also cultured within the pseudomembrane. The cat was received antimicrobial therapy for his Pseudomonas pneumonia. In humans, fibrinous tracheal pseudomembranes occur uncommonly as a complication following endotracheal intubation and rarely due to infectious organisms. As there was no prior history of endotracheal intubation, the development of fibrinous tracheal pseudomembrane in this cat was suspected to be secondary to Pseudonomas aeruginosa aspiration pneumonia. Relevance and novel information The present case report is the first to describe a tracheal pseudomembrane in a cat. Bronchoscopy-guided gentle traction and subsequent removal of the tracheal pseudomembrane resulted in a complete resolution of the clinical signs.

History Of

Phlegmonous gastritis was diagnosed in 2 yearling fillies that were presented with a 1-wk history of fever, lethargy, and hypoproteinemia, associated with a previous diagnosis of equine proliferative enteropathy based on clinical signs and PCR assay detection of Lawsonia intracellularis in fecal samples. Abdominal ultrasound revealed enlargement of the stomach and expansion of its submucosal layer with hypoechoic fluid, as well as thickened hypomotile small intestinal segments. Given the poor prognosis and poor response to treatment, both horses were euthanized, one on the day of presentation and the other after 3 wk of intensive medical management including a combination of antimicrobials, analgesics, and intravenous colloids. At autopsy, acute mural gastritis characterized by severe submucosal edema with suppurative inflammation (i.e., phlegmonous gastritis) and necroulcerative enteritis compatible with the necrotizing form of equine proliferative enteropathy were identified in both horses. The gastric inflammation was associated with thrombosis and mixed bacterial populations, including Clostridium perfringens, that were confined to the submucosa without evidence of mucosal involvement; toxin genes compatible with C. perfringens type C were identified in one case. Human phlegmonous gastritis is an uncommon, often-fatal pyogenic infection that is often associated with mucosal injury, bacteremia, or immunocompromise. Our finding of this unusual gastric lesion in 2 horses with similar signalment, clinical disease, and spectrum of postmortem lesions suggests a similar etiopathogenesis that possibly involves local, regional, or distant hematogenous origin, and should be considered a potential complication of gastrointestinal mucosal compromise in horses.

Clinical findings and investigations A 14-year-old female neutered domestic shorthair cat was referred for investigation of progressive hair loss, muscle wasting and hind limb weakness. Diabetes mellitus had been diagnosed 8 months earlier and was well controlled. Abnormalities on serum biochemistry included persistent mild azotaemia, hypochloridaemia, hypokalaemia, metabolic alkalosis and elevated creatine kinase. Physical examination revealed a pot-bellied appearance, with muscle wasting, marked thinning and fragility of the skin, bilaterally symmetrical alopecia, a gallop rhythm and systolic hypertension (173 mmHg). A large, lobulated left adrenal mass was identified using abdominal ultrasound. Confirmation of diagnosis Primary hyperaldosteronism was diagnosed based on an elevated plasma aldosterone concentration and normal plasma renin activity. Hyperprogesteronism was confirmed by adrenocorticotrophic hormone stimulation test. Practical relevance This is only the second reported case of hyperaldosteronism and hyperprogesteronism in the cat. Clinicians should be alert to the possibility of concurrent hyperaldosteronism and hyperprogesteronism in cats with adrenal tumours showing clinical signs referable to both conditions. The putative mechanism is either increased secretion of aldosterone and progesterone from neoplastic cells of the zona glomerulosa and fasciculata/reticularis, respectively, or increased production of progesterone, as an intermediate in the synthesis of aldosterone, from neoplastic cells of the zona glomerulosa alone.

A 5-year-old female spayed Cane Corso was referred for further investigation and treatment of a splenic torsion and an abdominal mass. The dog presented with a history of anorexia, depression and vomiting of 4 days’ duration. Physical examination revealed pain on abdominal palpation. On a plain radiograph of the abdomen, a cranial abdominal mass and splenomegaly were present. On CT images of the abdomen, a twisted splenic pedicle, splenic torsion and a well-defined mass in the left cranial abdomen were observed adjacent and caudal to the greater curvature of the stomach. The dog underwent a midline coeliotomy, a total splenectomy and a partial gastrectomy to resect the mass attached to the great curvature of the stomach. Omental torsion was diagnosed on gross and histological examinations of the mass. The dog was reported by the owners to be free of clinical signs 2 years after surgery.

A juvenile, wild-caught prairie falcon ( Falco mexicanus) kept for falconry was presented to a veterinary hospital for intermittent opisthotonos and torticollis. Clinical examination, complete blood count, serum biochemistry panel, and fecal analysis were unremarkable. Clinical signs did not resolve, and the bird was euthanized 6 mo after the appearance of clinical signs. Autopsy revealed a mild, unilateral hydrocephalus and nematodes within the thoracic air sac. Histopathology demonstrated mild, unilateral hydrocephalus; scattered glial nodules; meningeal nematode sections; and meningeal and intraventricular embryonated eggs. Morphology and molecular characterization were consistent with the air sac nematode Serratospiculum or Serratospiculoides spp. Air sac nematode infection can be associated with air sacculitis or pneumonia in falcons. Aberrant migration of air sac filariid nematodes Serratospiculum or Serratospiculoides spp. into the nervous system resulting in clinical disease is rare, but should be included in the differential diagnosis of neurologic diseases in falcons.

In this paper a case of periosteal proliferative polyarthritis in an 11-year old, female Siamese cat, that was admitted to the Surgery Clinic of the Veterinary School, A.U.Th., with a 6-month history of non-weight bearing lameness of the left thoracic limb, is described. At physical examination, restricted range of motion of the left elbow joint, local swelling and pain were detected. In the radiological examination of the affected joint the main finding was a periarticular extensive and irregular periosteal new bone formation. The results of the complete blood count and routine serum biochemistry were within normal limits and the cat was serologically negative for FeLV and FIV. Synovial fluid examination showed a lymphoplasmacytic pleocytosis, while the bacterial culture was negative. Prednisolone given at an anti-inflammatory dose for two consecutive weeks resulted in a marked improvement of the clinical sings. However, two months after the end of the treatment lameness reappeared, but this time in the contralateral thoracic limb, due to the involvement of the same joint. Radiology revealed the same type of lesions in the right elbow joint, whereas the left became ankylosed. Again, prednisolone, given at an immunosuppressive dose for two weeks, did not improve but fairly the clinical condition of the animal and the radiological changes as well. For this reason azathioprine at the dose of 1 mg/kg BW, every 48 hours, was added to therapy that lasted for 5 months. Transient mild leukopenia, that resolved after decreasing the dose of azathioprine by 25%, was the only adverse side effect noticed. At the end of the treatment, regression of the radiographical lesions in both elbows enabled the cat to walk with a stilted gait, despite the development of joint ankylosis bilaterally. The disease was kept in remission during the 12-month follow up period.

This case report is about a seven-year-old male neutered European Shorthair cat infected by Dirofilaria immitis as the first reported autochthonous Dirofilaria immitis infection in Austria. There was no history of periods abroad. Echocardiography showed suspected D. immitis in the right cardiac chamber with increased pulmonary pressure and ascites. Surgical removal of the heartworms was performed. Twenty adult heartworms were removed by transvenous jugular approach under general anesthesia and stored in 4% formalin. Five out of 20 specimens were examined via light and stereomicroscopy and feline heartworm infection was confirmed. Amplification of a 203 bp or 724 bp fragment of the cytochrome c oxidase subunit I gene was unsuccessful. After surgery the cat developed acute renal failure but recovered quickly. One year later, the cat underwent a control examination including echocardiography and blood work. There were no more D. immitis detectable at echocardiography. Lung pressure was mildly increased. Complete blood count and creatinine were unremarkable. The Knott’s test and Dirofilaria-Antigen-test produced negative results. The cat did not show any clinical signs during the follow-up period. The aim of this case report is to highlight the growing risk of acquiring infection with D. immitis not only for Austrian dogs, but also for cats. This case report represents the first report of autochthonous D. immitis infection in Austria. Moreover, even if the prognosis in cats with caval syndrome due to feline heartworm disease is guarded to poor, surgical removal of the filariae can be a successful treatment option.

An eight-year-old spayed female Yorkshire terrier was presented with a one-month history of conspicuous weight-bearing lameness in the right hindlimb, mild anorexia, intermittent vomiting and marked polydipsia and polyuria. Radiographs revealed circular radiolucent foci of variable size in the skeleton. Haematological and serum biochemistry examination revealed mild leucopoenia with severe neutropaenia, mild non-regenerative anaemia, moderate thrombocytopoenia, moderate hyperglobulinaemia, mild hypoalbuminaemia, mild azotaemia and moderate hypercalcaemia. Quantification of serum immunoglobulins revealed elevated IgA and IgG. Serum protein electrophoresis showed a broad appearance with a β-region spike. Plasma cells accounted for 7.6% of the cells in the bone marrow. Serum immunofixation electrophoresis (IFE) revealed IgA lambda gammopathy. Immunohistochemistry in the bone marrow was diffusely positive for multiple myeloma oncogene 1 (MUM-1) and CD20. To our knowledge, this is first case report of multiple myeloma associated with IgA lambda gammopathy confirmed via IFE and immunohistochemical expression of MUM-1 in a dog.

Gallbladder mucocoele (GBM) is an abnormal, intraluminal accumulation of inspissated bile and/or mucous within the gallbladder. Older, small- to medium-breed dogs seem to be predisposed, but no sex predilection has been identified. Clinical signs are often non-specific and include vomiting, lethargy, anorexia, abdominal pain, icterus and polyuria–polydipsia. Results of a complete blood count may be unremarkable, but serum biochemistry usually reveals increased liver enzymes. The ultrasonographic appearance is diagnostic and well described in the literature. Surgical intervention for the treatment of GBM remains the therapeutic gold standard, with short- and long-term survival for biliary surgery being 66%. The worst outcome is seen in those dogs requiring cholecystoenterostomy. With GBM becoming an apparently increasingly common cause of extrahepatic biliary disease in canines, it is essential that clinicians become familiar with the current literature pertaining to this condition. Numerous predisposing factors are highlighted in this review article and the role of certain endocrinopathies (e.g. hyperadrenocorticism and hypothyroidism) in the development of GBM is touched upon. Furthermore, the aetiopathogenesis of this disease is discussed with reference to the latest literature. Cholecystectomy remains the treatment of choice, but other options are considered based on a current literature review.

Gastric Neoplasia

Background: Gastric neoplasia is rare, corresponding to less than 1% of cases, with a lower prevalence of those involving smooth muscle tissues. In these cases, clinical signs worsen in the occurrence of pyloric obstruction, leading to clinical manifestations such as chronic emesis. The exeresis of the neoplasm is promoted as a therapeutic measure to reestablish gastrointestinal flow. There partial gastrectomy followed by gastroduodenal anastomosis, using the Billroth I technique, is among the available surgical techniques. The therapeutic success of the Billroth I technique after pylorectomy was reported in a dog with gastric leiomyoma.Case: Canine, poodle, 9 years old, 9.5 kg, with a history of chronic vomiting starting three months ago, progressive weight loss, and melena, previously treated by another Veterinarian as idiopathic gastroenteritis. The physical evaluation of the animal showed a state of normal consciousness, body score 4/9, pale ocular and oral mucous membranes, respiratory rate 20 mpm, heart rate 166 bpm, a rectal temperature of 37.9 °C, and dehydration degree of 8.0%. Blood count showed normocytic normochromic anemia and leukocytosis with shift to the right. Radiographic and endoscopic examinations were not noteworthy. Endoscopic biopsy after a histopathological evaluation showed no cellular or tissue atypia. On the other hand, abdominal ultrasound assessment revealed thickening with loss of echotexture and definition of the muscular layer of the gastric wall, pyloric and duodenum region compatible with benign antral muscle hypertrophy and/or pyloric neoplasia. The animal worsened five days after the initial treatment, with progressive episodes of emesis and melena, opting for an exploratory laparotomy. A mass of firm consistency measuring approximately 2.5 × 6.0 cm in diameter was found in the pyloric region, opting for a pylorectomy. The excised fragment was sent for histopathological examination. Then, gastroduodenal anastomosis was performed using the Billroth I technique. After the surgery, a pasty diet was introduced orally, without using gastroenteric tubes. Dry food was offered ten days after the surgical procedure. The animal returned for clinical reevaluation on the fifteenth day and was clinically well. Histopathological examination revealed a diagnosis of gastric leiomyoma.Discussion: The casuistry of gastric neoplasia in dogs has a low incidence, with an occurrence of less than 1%, with adenocarcinoma being the most common type. However, there are less frequent reports of other gastric neoplasia, such as smooth muscle tumors. Abdominal ultrasonography is indicated for the diagnosis of gastrointestinal changes, proof of which ultrasonography was of paramount importance in this case. The surgical procedure of pylorectomy guaranteed a margin of one centimeter, meeting the principles of oncological surgery. Absorbable monofilament suture materials are the choice for the synthesis stage in hollow organs, being used in this case. The most-reported expected complications of gastrointestinal surgeries aiming at removing neoplasms are vomiting, anorexia, melena, hematochezia, hematemesis, necrosis with anastomotic ulceration, and, consequently, septic peritonitis, which were not reported in this case. The life expectancy of patients with gastric neoplasia is quite variable, with longer survival in cases of benign neoplasia. Therefore, the type of neoplasia in this case, together with the appropriate choice of therapy and the appropriate performance of the technique, was important for the good result achieved.
