Clinical characteristics and outcomes of primary adrenal hemangioma in a dog

Abstract

An 8-year-old 7.9kg castrated male Shih-tzu dog was presented to surgery with polyuria–polydipsia, intermittent abdominal pain and dermatological problems. The unilateral enlargement of the right adrenal gland was observed through ultrasound examination and based on this examination a hyperadrenocorticism was suspected. Upon physical examination, regional erythema was observed in the skin. An abdominal CT scan showed a well-defined retroperitoneal mass. Adrenalectomy via a midline abdominal approach was performed as well as optional treatments upon the approval of the owners. The histopathological diagnosis was that of an adrenal hemangioma without evidence of malignancy. Adrenal hemangioma was incidentally found in this dog during histological examination and this finding was an extremely rare case of the primary hemangioma in the adrenal gland.
