摘要
目的探讨胸腹部巨淋巴结增生症的多层螺旋CT特征,以提高对该病的认识。方法回顾性分析6例经病理证实的胸腹部巨大淋巴结增生的多层螺旋CT表现并复习相关文献。结果 6例中,男性5例,女性1例,年龄50~86岁,中位年龄69岁。4例病例行CT平扫及增强扫描,2例仅行平扫。病灶单发4例,其中前纵隔2例,后纵隔1例,腋下1例;多发2例,广泛累及腹膜后及肠系膜。病灶大小1.3~5.7cm。所有病灶边界较清,密度均匀,形态较规则。平扫CT值30~45 Hu,增强后72~98 Hu,病灶均匀强化,部分病灶周围可见血管密度影。结论典型的巨淋巴结增生CT影像学表现具有一定的特征性改变,多层螺旋CT对其具有较高诊断价值。
Objective To explore the multi-slice spiral CT features of giant lymph node hyperplasia in check and abdomen,and improve recognition of this disease.Methods Multi-slice spiral CT findings in 6 cases with giant lymph node hyperplasia in check and abdomen confirmed by pathology were retrospectively analyzed and review the literatures. Results six patients with giant lymph node hyperplasia in check and abdomen were confirmed including 1 women and 5 men with age range from 50 to 86 years(median age 69 years). 4 patients underwent plain and postcontrast enhanced CT,2 cases underwent plain scan. CT showed a single mass in 4 patients located at anterior mediastinum in 2,posterior mediastinum in 1,and armpit in 1. Multiple masses were located at retroperitoneum and mesentery in 2. The lesions ranged in size from 1.3 to 5.7 cm. CT showed all lesions with well-defined margin and regular shape. The plain scan CT value was 30~45 Hu,the vessel density shadow was seen around lesions when the enhancement was 72~98 Hu. Conclusion There are distinctive imaging findings in the cases of typical giant lymph node hyperplasia,and Multi-slice spiral CT scan is valuable in the diagnoses.
