Plain-English summary
A group of 30 dogs with prostate cancer (prostatic carcinoma) underwent CT scans to better understand the disease's characteristics. Common signs included areas of the prostate that looked uneven and distorted, along with changes in nearby lymph nodes and fat. Some dogs also showed signs of invasion into surrounding structures or changes in their bones. These findings can help veterinarians recognize and diagnose prostate cancer in dogs more effectively.

Abstract
Canine prostatic carcinoma (PC) has incompletely defined CT features. The purpose of this multicenter retrospective case series was to assess prostatic, regional, and distant findings of PC. Thirty dogs were enrolled. Consistent prostatic features included postcontrast heterogeneity with hypoattenuating, nonenhancing areas (30/30), capsular distortion (29/30), prostatic urethral effacement, displacement, or invasion (28/30), precontrast heterogeneity (27/30), and mineralization (24/30) which was always within or at the margin of the hypoattenuating areas. Consistent extraprostatic features included medial iliac lymph node enlargement (20/30), internal iliac lymph node enlargement (15/30), and periprostatic fat streaking or fluid (15/29). In a minority of dogs, there was lymph node mineralization, bladder trigone invasion, ureteral dilation, ductus deferens invasion, and bony changes consistent with hypertrophic osteopathy. Strongly suspected and potential bony metastases were noted infrequently (8/26), all in vertebrae regional to the prostate. In conclusion, these findings provide guidance on the expected CT features of canine PC.
