目的探讨腹盆腔巨大淋巴结增 生症(CD)的MSCT表现及临床、病理特点。 方法 结合临床与手术病理资料，回顾分 析16例CD的MSCT表现特点。结果 16例 Castleman病患者，其中男6例，女10例， 年龄分别为10-73岁，平均年龄38.2岁。 病理上，16例CD，其中13例为透明血管 型，1例为混合型，2例为浆细胞型。16例 中均为局限型CD，表现为腹盆腔的单发 肿块，呈类圆形或椭圆形，直径在2.0- 11.0cm间，平均5.6cm，其中，2个肿块 见钙化，2个肿块内见点片状低密度坏死 灶，1个肿块内见裂隙状低密度灶，边界 清晰，其余肿块均呈均质密度伴显著持续 强化，且其中1个肿块内见粗大血管影， 增强程度和腹主动脉相似。结论 均质软 组织密度肿块伴显著持续强化及钙化、少 数见低密度影是局限性CD的主要CT表现， 具有一定的特征性。

Objective To investigate the MSCT manifestations and clinical, pathological features of the pelvic and abdominal giant lymph node hyperplasia (CD). Methods With the combination of clinical and surgical pathological information, had a retrospective analysis of the MSCT appearances among 16 cases of CD. Results 16 cases of Castleman patients, including 6 males, 10 females, whose age were 10 to 73 years old, and the average age is 38.2. Pathologically, 16 cases were localized type, including 13 cases of hyaline vascular type, 1 cases of mixed type, 2 cases were plasma cell type. In those 16 cases of localized CD, manifested as abdominal and pelvic solitary mass, which were round or oval, 2.0-11.0cm in diameter, average 5.6CM. Among them, 2 mass had calcification, 2 masses showed point sheet low density necrosis, the crack-like low density area could be seen in 1 mass. slit like clear boundaries homogeneous density, with significant continued to strengthen showed the rest mass, and 1 of them within the masses see thick blood film, the degree of enhancement and abdominal aorta similar. Conclusion Homogeneous soft tissue density mass with significant sustained enhancement and calcification, few see the low density are the main limitations of CT CD performance, has certain characteristics.
