Ct Features

Case Description. An eight-year-old Golden Retriever was presented with hypercalcemia and a complex abdominal mass. Clinical Findings. A well-defined, heterogeneously contrast-enhancing, cavitary, soft tissue attenuating, non-organ associated abdominal mass was identified caudal to the right kidney. This mass was confluent with the distal tip of the right limb of the pancreas. A connected large, rim enhancing, cystic subcutaneous mass was also present in the right lumbar subcutaneous tissues, and there were multiple fistulous tracts through the hypaxial musculature. Treatment and Outcome. The dog underwent a surgical exploratory laparotomy and a gossypiboma was removed from the intra-abdominal mass; the cystic extra-abdominal mass was drained percutaneously. Surgical recovery was uneventful and a follow-up CT after 3 months was consistent with resolving granulomatous inflammation and fibrosis. Clinical Relevance. The presence of multiple peripherally enhancing tracts extending from the abdominal mass through the hypaxial musculature is a CT feature which has not yet been described in the veterinary literature. Additionally, incorporation of the pancreas into the abdominal mass has also not yet been described in the veterinary literature.

A 2-year-7-month-old female intact African hedgehog was presented with a subcutaneous mass around the right side of the neck as well as an intra-abdominal mass found during palpation. Surgical excision and exploratory laparotomy were performed. A uterine mass was identified during laparotomy and ovariohysterectomy was performed. The botryoid mass measured [Formula: see text][Formula: see text]cm and was located in the right uterine horn. It had a meat-like texture and was yellow-white and dark red in color. The removed subcutaneous mass measured [Formula: see text][Formula: see text]cm. The mass was well-encapsulated and had a yellow-white homogeneous texture on the cut surface. Histologically, the myometrium was invaded by neoplastic cells and the tissue boundaries were not obvious. Neoplastic cells were arranged in a whirling or intersecting pattern, with strong angiogenesis present. Vacuolated nuclei were round and oval to cigar shaped, with one to multiple nucleoli present. Immunohistochemistry revealed a positive reaction for CD10, but a negative reaction for smooth muscle actin (SMA) and desmin in the uterine neoplastic cells. Histologically, well-differentiated adipocytes with sheets of undifferentiated polygonal neoplastic cells, which were characterized by vacuolated nuclei with prominent multiple nucleoli, were found in the subcutaneous mass. Neoplastic cells of the subcutaneous mass were positively stained with antibodies of MDM2 and estrogen receptor (ER), but failed to give a positive result for vimentin because the cross-species interaction was insufficient. The definitive diagnosis was endometrial stromal sarcoma and liposarcoma in an African hedgehog.

Mechanical Intestinal Obstruction

The acute abdomen has many etiologies frequently encountered in emergency surgical units. Approximately 20% of surgical admissions for acute abdominal conditions are for intestinal obstruction. Clinicians often overlook rarer causes. A 43-year-old man presented to the emergency ward with the clinical findings of ileus. Computed tomography revealed a heterogeneous necrotic 168 × 100-mm mass between the sigmoid colon and urinary bladder. Physical examination revealed a palpable intra-abdominal mass that was removed via exploratory laparotomy. On histopathologic examination, the mass was identified as a seminoma. The literature contains few reports of seminoma as a cause of acute abdomen and ileus, mostly seen between the ages of 30 and 40 years. We report a patient with seminoma arising in an undescended testis that presented as a palpable painful lower abdominal mass and mechanical intestinal obstruction, despite the large diameter of the mass, as well as review relevant literature.

Adrenal hemangioma is an extremely rare benign and non-functioning neoplasm of the adrenal gland. We report a case of a 71-year-old woman admitted for intermittent abdominal pain and abdominal distension associated with vomiting and chronic constipation for 5 years. Physical examination revealed a large abdominal mass. Both computed tomography scan and magnetic resonance imaging suggested hemangioma in the right lobe of the liver. Laboratory examinations and tumour markers were within normal limits, except for hypochromic microcytic anemia. The mass was removed intact by conventional surgery and histopathology revealed a cavernous hemangioma of the adrenal gland with no signs of malignancy. Surgical resection was curative, with no recurrence at the 2-year follow-up.

Case summary A 10-year-old neutered male domestic shorthair cat was diagnosed with renal adenocarcinoma associated with hypertrophic osteopathy. The cat was referred for chronic ambulation difficulties. The physical examination showed a painful thickening of all four limbs, a right cranial abdominal mass and a conjunctival hyperaemia. Radiographic findings were consistent with extensive periosteal new bone formation involving not only the diaphyses of the fore- and hindlimbs, but also of the pelvis, tarsus and carpus. Abdominal ultrasonography and CT revealed a mass within the right kidney and a primary neoplasm was suspected. A ureteronephrectomy of the right kidney was performed and histopathology confirmed the diagnosis of renal adenocarcinoma. Although clinical improvement of the lameness occurred after surgery, no radiographic changes of hypertrophic osteopathy lesions were observed at the 9-month follow-up. Relevance and novel information Feline cases of hypertrophic osteopathy are rarely reported in the literature and only a few of them were associated with abdominal neoplastic diseases. To our knowledge, this is the first case of renal adenocarcinoma associated with hypertrophic osteopathy in a cat.

A two years old Kathiawar stallion was reported with the history of two, pedunculated hard mass medially on the thigh and hock of the right hind limb, progressively increasing for the past two months. Fine needle aspiration cytology revealed fibrosarcoma.The tumour on the medial aspect of the thigh was injected with cisplatin intra-tumorally at a dose rate of 0.3 mg/cm3 of tumour volume and was exposed to ECT. The tumour on the medial aspect of the hock was excised incompletely to preserve skin and subcutaneous tissues around the tumour for wound opposition and treated with intra-tumoral injection of cisplatin followed by ECT. Following electrochemotherapy complete response was noticed onthe 3rd and 4th week for the tumours on the thigh and hock respectively. No recurrence was noticed during the follow-up period of one year revealing ETC with cisplatin as a single treatment and also in combination with surgery is effective for the treatment of fibrosarcoma in equines.

An 8 yr old, reportedly castrated male Boston terrier presented with a history of generalized hyperesthesia and intermittent shifting leg lameness. Physical examination revealed a caudal abdominal mass and bilateral shoulder pain. A complete blood count, serum biochemistry panel, and urinalysis were unremarkable. Thoracic radiographs demonstrated bony proliferation and lysis of the third sternebra, an expansile lesion of the left tenth rib, and lucency in both proximal humeral metaphyses. Abdominal radiographs and ultrasound revealed a soft tissue mass within the caudoventral right abdomen. Ultrasonography also revealed an enlarged lymph node within the right retroperitoneal space. Exploratory laparotomy identified the mass as a retained testicle. A cryptorchidectomy, lymph node biopsy, and bilateral percutaneous core biopsies of the proximal humeri were performed. Histopathologic examination revealed malignant seminoma of the testicle with metastasis to lymph node and bone. Adjuvant chemotherapy was recommended, but it was declined by the owner. All follow-up was lost. This case highlights a unique case for causative hyperesthesia secondary to a novel site of metastasis from malignant seminoma. Metastasis to bone has not been reported in humans or dogs and represents a very unusual and aberrant variant of the normally relatively benign biological behavior of seminoma in the dog.

Adrenocortical carcinoma is a rare malignant tumor which can reach large sizes if it is nonfunctioning. In that situation, it can pose diagnosis dilemmas regarding the origin and the nature of the tumor. We reported a case of non-secreting and large right Adrenocortical carcinoma which arose in the posterior costophrenic angle mimicking a liver tumor. A 45-year-old man presented with a voluminous abdominal mass in the right upper quadrant. The different imaging modalities including ultrasound computed tomography and magnetic resonance imaging were discordant as regards the hepatic or the adrenal origin of the tumor. Percutaneous biopsy allowed to determine the diagnosis of the cortico-adrenal tumor. The patient underwent laparotomy. The tumor which arose from the right adrenal gland was resected. Pathology confirmed the diagnosis of adrenocortical carcinoma with histological factors of poor prognosis. The patient was given Mitotane as adjuvant therapy. After six years of follow-up, a tumor recurrence has been diagnosed.

Histologic Evaluation

Two young adult male Domestic Shorthair cats living in the southeastern United States were evaluated for signs attributable to partial intestinal obstruction. Physical examination indicated a palpable abdominal mass in each animal. Exploratory laparotomy revealed a large extraluminal mass involving the ileum and mesentery with adjacent mesenteric lymphadenopathy in cat No. 1 and an abscessed mass in the distal duodenum in cat No. 2. Mass resection and intestinal anastomosis were performed in both cats. Histologic evaluation indicated that the intestinal lesions involved primarily the outer smooth muscle layer and serosa and consisted of eosinophilic granulomatous inflammation with multifocal areas of necrosis. In Gomori methenamine silver–stained sections, broad (2.5–7.5 μm), occasionally branching, infrequently septate hyphae were observed within areas of necrosis. A diagnosis of Pythium insidiosum infection was confirmed in both cats by immunoblot serology and by immunoperoxidase staining of tissue sections using a P. insidiosum–specific polyclonal antibody. Cat No. 1 was clinically normal for 4 months after surgery but then died unexpectedly from an unknown cause. Cat No. 2 has been clinically normal for at least 9 months after surgery and appears to be cured on the basis of follow-up enzyme-linked immunosorbent assay serology.

Patient is a 77 year old female who presented to the outpatient dermatology clinic due to progressive massive leg swelling. Physical exam demonstrated bilateral lower extremity chronic lymphedema with stasis dermatitis changes with the left more significant than the right. The patient was diagnosed with elephantiasis nostras verrucosa (ENV) and was treated with leg elevation and arranged for follow-up with a chronic lymphedema clinic. ENV is a rare complication of non-filarial chronic lymphedema. Its pathogenesis is characterized by long-standing lymphatic obstruction, which may occur due to a variety of obstructive diseases. This can lead to accumulation of proteinaceous fluid in the dermis and subcutaneous tissues causing further lymphatic obstruction and edema followed by hyperkeratosis, fibrosis, and formation of papillated, verrucous papules. Differential diagnoses to consider include venous stasis dermatitis, cellulitis, lipodermatosclerosis, pretibial myxedema, and lymphatic filariasis. Mainstays of treatment of ENV include elevation of the affected body part, compressive hosiery, and antibiotic prophylaxis for superimposed infection [1].

Abstract OBJECTIVE To evaluate the feasibility of CT lymphangiography via intrametatarsal pad injection in cats with chylothorax. ANIMALS 7 client-owned cats. PROCEDURES This was a multicenter, retrospective, descriptive study. Medical records and imaging data from 4 veterinary hospitals were reviewed to identify cats with chylothorax that had undergone intrametatarsal pad injection via CT lymphangiography. In total, 7 client-owned cats were included in the study. Signalment, history, image findings, and follow-up data were recorded. Descriptive statistics were used to analyze the success rate of thoracic duct (TD) enhancement and describe relevant clinical findings. RESULTS Enhancement of TDs was successful in 6 of the 7 cats within 5 to 15 minutes after initiating intrametatarsal pad injection under general anesthesia. Successful migration of contrast medium into the lymphatic vessels cranial to the popliteal lymph nodes was observed in all cats within 5 minutes after injection. The recommended dose of contrast medium to achieve TD enhancement was 1 mL/kg (0.5 mL/kg/pad; concentration, 350 mg of iodine/kg). Only 1 cat had mild swelling of the paws after the procedure, and it recovered quickly without pain medication; no cats experienced lameness. Similar to dogs and unlike in previously published reports, 72% of TD branches were located in the right hemithorax. CLINICAL RELEVANCE CT lymphangiography via intrametatarsal pad injection is a feasible and safe procedure for cats with chylothorax. This technique provides detailed information regarding the unique TD anatomy and cisterna chyli location. It also contributes to surgical planning.
