An 18-year-old, female Shih Tzu dog was presented at Prasu-Arthorn Animal Hospital, Faculty of Veterinary Science, Mahidol University with the clinical signs of abdominal enlargement, constipation and urine incontinence. The survey abdominal radiographs demonstrated only a caudal large oval soft tissue abdominal mass and abdominal ultrasonography was suggested to indicate the mass origin. However, ultrasonographic finding did not identify the mass location and tissue invasiveness so computed tomography (CT) was requested. The CT result revealed that the mass was a mixed heterogenous attenuating and fluid attenuating mass (8.56 x 5.47 x 6.72 cm) at the uterine body and involved the vagina area without contrast enhancement soft tissue invasions. Moreover, CT presented a hyper-attenuated urinary bladder (UB) mass (1.31 x 1.31 cm) and bilateral ovarian cysts with cystic lesions at both uterine horns. According to the CT results, surgical excision was applied to remove vaginal and urinary bladder masses and ovariohysterectomy (OVH) was done. For the histological results, leiomyoma was diagnosed on the cranial vagina and UB. This case study suggests that CT is a useful diagnostic imaging modality that provides a very useful information for surgical planning and the treatment of large abdominal mass.
