Adrenal venous malformation is an uncommon disease. We report a case of an incidentally diagnosed adrenal cystic mass during an evaluation for gastritis in a child. A 14-year-old girl admitted to our pediatric department for epigastric pain. After the gastroscopy, she was diagnosed with hemorrhagic gastritis. A 5.5 cm-sized cystic mass was incidentally found adjacent to her left adrenal gland during an ultrasound examination for evaluating her abdominal symptoms. She underwent laparoscopic surgery for the diagnosis and treatment of this cystic mass, which was confirmed to be venous malformation at pathologic diagnosis.

An 8-year old castrated domestic long-hair cat was presented with a two week history of abdominal distension. Physical examination revealed a non-painful, fluctuant, palpable mass in the right craniodorsal abdomen, and unilaterally muffled heart sounds on the right thorax. Routine clinico-pathological values were unremarkable apart from mild azotemia with a concurrent urine specific gravity of 1.031, which reflect a degree of renal dysfunction. Radiographic and ultrasound examinations of the thorax revealed the cardiac enlargement to be due to the congenital peritoneo-pericardial diaphragmatic hernia with liver occupying the right half of the pericardial sac. There was also a mild gypertrophy of the heart. Radiography and ultrasonography of the abdomen showed the mass to be composed of a large fluid filled cystic structures surrounding the right and left kidneys, and the kidneys themselves were of increased echogenecity. A diagnosis of perinephric pseudocysts was made. The patient responded well to the surgical procedures. Perinephric pseudocysts and peritoneo-pericardial diaphragmatic hernia in the cat are rare, and a case is described and the literature is reviewed in this report.

A case of leiomyosarcoma is reported in a 9-year-old female Jin Do. The dog has been suffered from 1 week history of abdominal distension, dyspnea, depression and anorexia. On routine physical examination, radiology and ultrasound, a large occupying mass was noted in the reptroperitoneum. Due to poor prognosis, the uterine mass removed by ovariohystrectomy and submitted to pathology department for diagnosis. Grossly, the mass was firm, tan and contained several areas that were necrotic and hemorrhagic. (omitted)

Ectopic thyroid gland is a defined as thyroid tissue located in a site other than its usual pre-tracheal location. Ultrasound examination, CT scan, thyroid scan, and thyroid iodine uptake test are all valuable modalities for a differential diagnosis. Although most of cases are asymptomatic, treatment is indicated when there are symptoms related to progressive growth of mass. This article reports a ectopic thyroid cyst in the anterior neck that was similar to deep neck infection accompanied by acute airway obstruction.

We have experienced a case of occult papillary thyroid carcinoma presenting as an anterior mediastinal mass in a 40-year-old man. The CT scan revealed a huge mass behind the manubrium of the sternum but the ultrasound examination failed to detect any lesion and developmental defect in the thyroid. Excision of the mediastinal mass and total thyroidectomy were carried out. Histologically, the mediastinal mass turned out to be papillary carcinoma without any portion of the normal thyroid tissue or normal lymph node tissue and the thyroid gland showed a tiny papillary carcinoma with the diameter of 0.3cm. Although a mediastinal mass as the sole presentation of the thyroid carcinoma is very rare, we suggest that a mediastinal mass should be added to the list of possible metastatic thyroid carcinoma.

A 12-year-old, castrated male, mixed dog presented with a history of gradual abdominal distention for a year and anorexia recently, with abdominal radiographs showing a gastric pylorus distention. A solitary, pedunculated, heterogeneous mass arising from the mucosal layer in the pylorus with intact wall layers was identified during ultrasound and computed tomography. The gastric muscular layer was evenly thick. After surgical excision of the mass, histological examination confirmed hypertrophic pyloric gastropathy with polypoid growth and Helicobacter spp. infiltrating the gastric mucosal epithelium. This is the first reported diagnostic imaging case of hypertrophic pyloric gastropathy with Helicobacter spp. in a dog.

In this case report, we present a rare case of lipoma of the tendon sheath localized to the wrist which caused median entrapment neuropathy and was successfully treated with surgical excision. Dynamic examination using ultrasonography revealed the exact location of the lipoma. Electrodiagnostic study (EDX) was done before surgery to elucidate combined neuropathy, and surgery for ulnar neuropathy around elbow was also performed simultaneously. Diagnostic ultrasound can be used for dynamic examinations with real-time visualization.

Splenic myelolipoma is a rare tumor in dogs with an unclear origin. A male 13-year-old Schnauzer dog was presented because of a bump on the left side of the abdomen. Clinical examination and abdominal ultrasound revealed a mass in the spleen. A total splenectomy was carried out, and histopathology revealed a splenic myelolipoma. Before surgery, the patient showed high serum alanine aminotransferase levels, which returned to normal eight months after the resection. Unfortunately, the postoperative follow-up showed increased serum cholesterol and triglyceride levels, suggesting liver compromise. This is the first report of a splenic myelolipoma in Colombia.

A 6-year-old female Chihuahua was presented to the Animal Medical Center for surgical resection of a perineal mass that had recently increased in size. Ultrasonography revealed a large, homogeneous fatty mass with irregular margins between the surrounding muscle layers due to infiltrating fatty tissues. Cytological findings from fine-needle aspirates revealed numerous sheets and clusters of adipocytes, which was consistent with the fatty mass. Based on ultrasonographic and cytological findings, an infiltrative lipoma was suspected. During the surgery, the perineal mass was found to be non-encapsulated, irregularly marginated, and extensively distributed into the surrounding muscles. The mass extended inside the pelvic cavity and left anal sac. The perineal mass was surgically removed and submitted for histopathologic examination. Histopathology confirmed that the mass was an infiltrative lipoma invading into the anal sac and surrounding muscles. The present report was an unusual presentation of infiltrative lipoma that invaded the anal sac in the perineum.

An 8-year-old spayed female, mixed dog presented multiple, bloody exudative skin lesions on the bilateral flank which spread 1 week after mastectomy for treatment of mammary gland tumor (MGT). Multiple, ill-marginated, irregular, and heterogeneously thickened cutaneous and subcutaneous lesions and enlarged lymph nodes were identified in ultrasound and computed tomography. Histopathological examination confirmed adenocarcinoma with lymphatic invasion presumed to be metastatic MGT. Clinical signs improved after chemotherapy but died after 1 month. This study suggests that cutaneous metastasis be considered for differential diagnosis of cutaneous lesions in dogs with a history of MGT, although skin metastasis from MGT is rare.
