【摘要】：正患者女,60岁,B超发现"盆腔包块"1年。CT:膀胱左前壁肿块,边界清晰,大小4.2cm×5.2cm×3.8cm,位于膀胱壁内外,密度略不均匀;动脉期明显不均匀强化,瘤周较多纡曲血管影;延迟期持续强化。CTA示病灶由膀胱下动脉分支供血,呈血管包绕征(图1A)。MRI:膀胱肿块呈T1WI等、低信号,T2WI等、高信号;DWI示病灶不均匀高信号(图1B);增强扫描明显不均匀持续强化,瘤周血管扩张(图1C)。行膀胱全切除术,术中见肿瘤位于膀胱左前壁,质韧。病理:瘤组织由梭形和上皮样细胞组成,间质血窦丰富。免疫组化:HMB45(+,图1D),PNL2(+),PGP9.5(+),CD99(+)。病理诊断:膀胱壁血
[Abstract]:The female patient was 60 years old. B-mode ultrasound showed "pelvic mass" in 1 year. CT: mass in the left anterior wall of bladder, with a clear margin, was 4.2cm 脳 5.2cm 脳 3.8cm in size and located inside and outside the bladder wall. The density is slightly uneven; The arterial phase was obviously inhomogeneous enhanced, and there were more convoluted vessels around the tumor. Delayed phase continuous enhancement. CTA showed that the lesion was supplied by the branches of the inferior bladder artery and showed a vessel wrapping sign (Fig. 1A: MRI: T1WI et al., low signal intensity T2WI, high signal intensity; DWI showed heterogeneous hyperintensity (Fig. 1B); Contrast-enhanced scanning was not uniform and continuous enhancement, peripheral vasodilation (Fig. 1). Total cystectomy was performed. The tumor was located on the left anterior wall of bladder during the operation. Pathology: the tumor tissue was composed of fusiform and epithelioid cells. The interstitial sinuses are abundant. Immunohistochemical staining: HMB45fig. PNL2 (PGP 9.5.) pathological diagnosis: bladder wall blood
