摘要
目的了解腹部castleman病的CT和MR表现以及与病理改变的联系。方法 2005-2011年12例经病理证实的castleman病,9例行CT平扫及增强扫描,3例行MR平扫及增强扫描。结果病变全部为局限型。病理包括透明血管型8例和浆细胞型4例。CT平扫为等密度病灶,2例伴有钙化,1例伴有囊变,增强扫描示6例透明血管型病灶均有明显持续强化且持续时间较长,1例浆细胞型病灶呈轻度~中度强化。3例行MR扫描,均为透明细胞型。平扫T1WI呈低信号、T2WI呈稍高信号,1例伴囊变,增强扫描均有明显持续强化且持续时间较长。结论 Castleman病的CT和MR表现与病理改变密切相关,透明血管型有可能术前提示,但浆细胞型影像学无特征性,确诊依赖组织病理学。
Objective To study CT and MR characteristics of Castleman disease in abdo- men and their pathologic basis. Methods Nine patients （From 2005 to 2011 ） with patho- logically proved Castleman disease were ungergone CT scanning, and three patients with pathologically proved Castleman disease were ungergone MR scanning. Results All lesions were localized, and classified into hyaline-vascular type in 8 and plasma cell type in 4. The lesions were of iso-density on plain CT, and calcifications seen in 2 and cystic changes seen in 1. The markedly and long-lasted enhancement was seen in lesion of hyaline vascular type, while mild-moderate enhancement was found in lesions of plasma cell type. Of the three had MRl^-~both of them were hyaline vascular type. showing hypo-intensity on T1WI, hyper- intensity on T2WI, and cystic changes seen in I. The markedly and long- lasted enhancement was seen. Conclusion CT and MR findings of Castleman disease are closely associated with its pathology. The Castleman disease with hyaline vascular type could be prompted preoperatively, but that with plasma cell type had characteristic imag- ing findings and only diagnosed on histopathologic examination.
