摘要
目的:探讨巨大淋巴结增生症的CT表现,以及与组织病理学联系。方法:7例经手术或活检后病理证实的巨大淋巴结增生症,均行CT平扫及增强扫描。结果:5例局限型,病理为透明血管型,2例弥漫型为浆细胞型;局限型CT表现为单发圆形或类圆形,密度均匀的软组织肿块影,边缘轮廓清,增强后肿块呈明显均匀持续强化,强化幅度接近主动脉强化幅度;弥漫型CT表现为多发大小不一的结节,密度欠均,边界欠清,周围脂肪层模糊,增强后呈轻中度不均匀强化,1例部分结节呈不完全环形强化。结论:巨大淋巴结增生症的CT表现与组织病理学密切相关,局限型(透明血管型)术前可以明确诊断,弥漫型(浆细胞型)无特征性影像学表现,确诊依赖组织病理学。
Abstract
Objective: To study CT characteristics of giant lymph node hyperplasia and their pathologic basis. Methods: Seven cases of pathologically proved giant lymph node hyperplasia were examined by plain and enhanced CT scanning. Results: In 5 cases with localized type of giant lymph node hyperplasia, which belonged to hyaline vascular type pathologically, the lesion presented as a solitary round or oval, iso-density soft tissue mass with smooth border. After contrast administration, obvious homogeneous sustaining enhancement was observed. The 2 cases with disseminated type, belonged to plasma cell type pathologically, the lesion presented as many dissimilar size nodules, inhomogeneous density, indistinct border, the periphery fat plane was fuzzy, with mild moderate non-uniform enhancement, 1 case showed incomplete ring-like enhancement. Conclusion: CT findings of giant lymph node hyperplasia are closely associated with its pathology. For localized type(hyaline vascular type), it is possible to make a correct diagnosis preoperatively. For disseminated type(plasma cell type) carries no specific CT signs, its verification is mainly based on pathologic examination.
