A twelve-year-old, spayed female Siamese cat was presented for health screening. Abdominal radiography revealed a large amount of mineral opacity substances of various sizes and shapes, along with mild gaseous dilation proximal to the lesion. Ultrasonography showed hyperechoic surface with acoustic shadowing at the ileum and wall thickening of the ileum. Enterotomy was performed to remove the foreign bodies, which were numerous hairball- and stone-like objects. Analysis of the enteroliths revealed a composition of calcium phosphate. Although enterolithiasis is considered rare in cats, it should be included in the differential diagnosis when numerous pebble-like mineral opacity lesions are observed.
A 9-year-old, intact female, Pungsan dog was referred for purulent vaginal discharge and depression. Abdominal radiographs revealed gas-filled and soft tissue opacity tubular structures in the mid to caudal abdomen. On ultrasonography, fluid-filled uterus and cervix accompanied by hyperechoic foci and reverberation artifacts were identified. Multiple hyperechoic foci were found within the uterine wall, indicating gas content. Escherichia coli was isolated from aerobic and anaerobic bacterial cultures. Radiological differential diagnosis of tubular shaped, dilated gas-filled structure, and gas in the wall of the structure should consider emphysematous pyometra with endometrial pneumatosis in intact female dogs with vulvar discharge.
Pseudo-pheochromocytoma is defined as an adrenal tumor that has the typical characteristics of pheochromocytoma likely hypertension but is histopathologically diagnosed to other types of adrenal tumors. 11-year-old, castrated male Maltese presented for a left adrenal mass with hypertension. According to clinical signs and radiological features, a temporary diagnosis was made of pheochromocytoma. The adrenalectomy was performed and the histopathological examination of the resected adrenal gland was diagnosed as cortical adenocarcinoma. This report describes the case of pseudo-pheochromocytoma in a dog and implies the salience that even if pheochromocytoma is diagnosed based on all test results, pseudo-pheochromocytoma should not be excluded.
