摘要
犬前列腺癌(PC)的 CT 特征尚未完全明确。这项多中心回顾性病例系列研究旨在评估 PC 的前列腺、区域和远处发现。共纳入了 30 只狗。一致的前列腺特征包括:对比后异质性,低增强、不增强区域(30/30),囊性变形(29/30),前列腺尿道阻塞、移位或侵犯(28/30),对比前异质性(27/30)和矿化(24/30),矿化总是在低增强区域内或边缘。一致的前列腺外特征包括髂内淋巴结肿大(20/30)、髂内淋巴结肿大(15/30)和前列腺周围脂肪条纹或积液(15/29)。少数病犬出现淋巴结矿化、膀胱三叉神经受侵、输尿管扩张、输精管受侵以及与肥大性骨病一致的骨质改变。强烈怀疑和潜在的骨转移并不多见(8/26),均发生在前列腺区域的椎骨上。总之,这些发现为犬 PC 的预期 CT 特征提供了指导。
Computed tomographic features of canine prostatic carcinoma
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.
