Abstract

Herein, we present the ultrasonography and computed tomography (CT) characteristics of an intramural calcified leiomyoma of the bladder in a dog. A 16-year-old, neutered male, Shih Tzu dog was referred to our hospital owing to corneal perforation. Serum chemistry findings and complete blood counts were unremarkable. A rounded hypoechoic intramural mass with internal hyperechoic foci was incidentally discovered on the ventral aspect of the bladder neck on abdominal ultrasonography performed for screening prior to corneal surgery. CT revealed a rounded hypoattenuated mass with central hyperattenuated foci at the level of the bladder neck. The mass was surgically excised and was diagnosed as leiomyoma based on histopathological findings.
