Primary omental abscessation was diagnosed in three dogs after laparotomy. Laparotomy was performed to explore an abdominal mass of unknown origin and chronic fat necrosis diagnosed in one dog as an incidental finding during ovariohysterectomy. Primarily hypoechoic masses not connected to any abdominal structures were visualized with abdominal ultrasound in three dogs. Suppurative inflammation was diagnosed from fine-needle aspirate evaluation in two dogs. Bacteria were cultured from two abscesses despite the absence of organisms on Gram stain, cytology, and histopathology. Foreign material was found in one abscess. All four dogs experienced weight loss and/or an episode of gastrointestinal signs. Primary omental abscessation may be preceded by omental vascular compromise and/or interaction of the omentum with foreign material.

AbstractThis is the first description of Multiple Congenital Ocular Anomalies (MCOA) in a silver coat Missouri Fox Trotter determined to be heterozygous for the Silver PMEL17 missense mutation associated with MCOA and a silver coat in other breeds. The stallion was treated for meningoencephalitis and bilateral uveitis of unknown origin. A complete ophthalmic examination and ocular ultrasonography were performed. As an incidental finding, the patient exhibited bilateral cystic lesions restricted to the temporal anterior uvea consistent with the Cyst phenotype and was genotyped heterozygous for the Silver mutation. Additionally, 4 other non-silver colored Missouri Fox Trotters were genotyped homozygous for the wild-type allele. Screening for PMEL17 mutation in Missouri Fox Trotters accompanied by ophthalmic phenotype characterization is recommended to determine the allelic frequency and facilitate informed breeding decisions since the silver coat color is particularly popular.

Red Currant

Intussusception is one of the most common abdominal emergencies in children. The classic triad of symptoms involves colicky abdominal pain, an abdominal mass, and red currant jelly stools, but this is seen in only about 15% of cases of children with intussusception. Early diagnosis and management reduce morbidity, risk for complications, and surgical intervention. Abdominal ultrasound is generally accepted as the gold standard for diagnosis. Treatment typically involves an air or hydrostatic enema; however, variability and controversies still exist in treatment and post-care management for nonsurgical cases. Variability also still exists in post-reduction care of children with intussusception. Feeding and monitoring times after nonoperative management differ between institutions. Some patients are advanced to feeds as tolerated while some others are placed in fasting to rest the bowel and prevent recurrence.

Diagnostic Investigations

A large exogastric leiomyoblastoma in a 48-year-old male revealed by asymptomatic upper abdominal mass is reported. Abdominal ultrasound, computerized tomography scan and magnetic resonance showed a 20 cm cystic lesion apart from liver and pancreas of undetermined origin. During hospitalization, massive intraperitoneal bleeding due to rupture of the mass was observed. An emergency laparotomy was carried out, and excision of a large, ruptured, cystic mass involving the greater gastric curvature was performed. Microscopy revealed a gastric leiomyoblastoma. Even if infrequent, massive intraperitoneal bleeding is a very serious complication of gastric leiomyoblastoma. Considering the difficulty of an accurate preoperative diagnosis and the risk of intraperitoneal rupture, the authors suggest that similar abdominal masses should be managed by quick diagnostic investigations and early surgical procedures.

This report describes multiple endocrine neoplasia in a dog, which is a rare hereditary disorder characterized by the presence of two or more neoplasms of different endocrine tissues within a patient. A 14 yr old dog was evaluated for polyuria/polydipsia, polyphagia, and abdominal enlargement. Adrenal-dependent hyperadrenocorticism with concomitant left thyroid enlargement and a presumed abdominal metastatic lesion were diagnosed by an adrenocorticotropic hormone stimulation test, ultrasonography, and computed tomography. Trilostane therapy was initiated and resolved the clinical signs for 2 yr at which time the dog presented with left testicular enlargement. The dog was euthanized and was diagnosed with adrenocortical carcinoma, thyroid carcinoma, an abdominal mass compatible with a metastatic lymph node, and bilateral interstitial cell testicular adenomas. To the authors’ knowledge, this is the first report to describe the concomitant association of these types of endocrine neoplasms in a dog. The concomitant presence of these neoplasms could represent a potential variant of multiple endocrine neoplasia; however, the presence of the interstitial cell testicular adenomas may have only been an incidental finding. If any of these tumors are diagnosed, veterinarians should perform a thorough clinical assessment to evaluate for the presence of additional endocrine neoplasms or hyperplasia.

A 60-year old man presented with a one week history of intermittent periumbilical pain. He had weight loss of half a stone over 6 weeks and abdominal distension for 2 weeks, there was no other systemic complaint. General examination revealed bilateral Dupuytren`s contracture and grade 4 finger clubbing. Abdominal palpation revealed a very large non tender mass. The Liver and spleen were difficult to assess because of the size of the mass. Rectal examination was normal. An abdominal Ultrasound showed a central abdominal mass of mixed echogenicity. CT scan showed a large lobulated mass with overlying serpinginous vessels with a clear plane posteriorly separating it from the retro-peritoneum. Liver, spleen and pancreas showed no abnormality. CT scan of the chest showed no abnormality. Core biopsy under ultrasound guidance revealed features consistent with a solitary fibrous tumor, haemangiopericytoma or angiosarcoma. The patient underwent a midline laparotomy. The huge mass was attached to the greater omentum by a pedicle with minimal adhesions to the lateral peritoneum. It was excised compeletly. The post-operative course was uneventful. Gross pathological findings macroscopically revealed the mass measuring 24x19x10 cm, weighing 3870 grams and on section it was a fleshy lobulated tumour with a few cystic areas. There was some attenuated fat on part of the surface. Histologically, the architecture was pattern-less with prominent stromal hyalinization, varying cellularity (mainly spindle and ovoid cells) and branching (haemangiopericytoma-like) vessels.

A gastric schwannoma is a rare primary spindle cell mesenchymal tumor of the digestive tract. Gastric schwannomas originate from Schwann cells of the peripheral nerves in the stomach. The majority of schwannomas are benign, slow growing tumors only a few of which develop into malignancies. Due to their indolent course, in most cases, gastric schwannomas are asymptomatic or discovered as an incidental finding on cross-sectional imaging or endoscopy. When symptomatic, the most common presenting symptoms are abdominal pain, upper gastrointestinal bleeding and intra- abdominal mass. Preoperatively, gastric schwannomas are difficult to differentiate from other mesenchymal tumors, such as gastrointestinal stroma or leiomyoma which develop from mesenchymal stem cells. The optimal management of the tumor is based on the symptoms of the patient, tumor size and histologic grading and the prognosis is excellent after complete surgical or endoscopic removal. Gastric schwannomas need multidisciplinary team management for definitive diagnosis and management, including specialists from gastroenterology, surgery, radiology and pathology.

Von Willebrand

Wilms tumor, known as well as nephroblastoma, is the most common primary malignant renal tumor in children. Over 95% of all renal tumors in patients under the age of 15 are Wilms tumors. The mean age at the time of diagnosis is 3.5 years. Wilms tumors are usually an incidental finding, a large abdominal mass discovered by a family member or pediatrician. Hematuria and hypertension can be present at the time of initial diagnosis. Up to 8% of the patients will have von Willebrand disease; therefore, all patients should have baseline coagulation studies. All patients should have either computed tomography of the abdomen and pelvis with oral and intravenous contrast or magnetic resonance imaging of the abdomen and pelvis with gadolinium. Treatment includes radical nephrectomy, chemotherapy, and, in some cases, radiotherapy. Emergency surgery is rarely. The disease-free survival rate is 86% for favorable-histology tumors and 64% for anaplastic tumors.

ABSTRACT A 6 yr old neutered male German shepherd dog was evaluated at a veterinary referral hospital following diagnosis of uroabdomen of unknown origin. A positive-contrast retrograde urethrogram identified diffusely irregular margins of the urinary bladder but no active leakage of urine into the peritoneal cavity. An abdominal ultrasound identified severe thickening and loss of wall layering of the apex of the bladder. The dog was initially managed with an indwelling urinary catheter; however, when the catheter was removed 5 days later, the dog developed a recurrent uroabdomen after an episode of dysuria. Subsequent surgical exploration identified numerous (>5), small (1–2 cm), black cyst-like nodules within the bladder wall at the apex of the bladder. A partial cystectomy, removing approximately 65% of the cranial bladder, was performed. Histopathology and immunohistochemistry of the bladder identified hemangiosarcoma of the bladder wall with chronic neutrophilic and hemorrhagic cystitis. The dog recovered from surgery without major complication and is still alive 9 mo following surgery. To the authors’ knowledge, this is the first report of successful treatment of canine bladder hemangiosarcoma by partial cystectomy in a dog.

Crossed Renal Ectopia

Crossed renal ectopia is a rare congenital anomaly usually associated with fused kidneys (90%). Most cases are asymptomatic and remain undiagnosed. We report an unusual case of nonfused crossed renal ectopia. The 11-year-old adolescent female patient was admitted with abdominal pain, anorexia, weight loss, and periumbilical mass. Although the initial clinical suspicion was a tumoral lesion, abdominal ultrasound and magnetic resonance examination revealed crossed renal ectopia without fusion. The renal ectopy was incidentally diagnosed, as described in 20 to 30% of cases. In this case, the associated nonspecific symptoms were a coincidence.
