浆膜型肝结核的CT表现

目的:探讨浆膜型肝结核的CT表现及诊断价值.方法:回顾性分析经病理证实的8例浆膜型肝结核CT表现,所有病例均行CT平扫及增强检查.结果:本组浆膜型肝结核8例中,6例单发,2例多发,共10个病灶.CT表现为肝包膜区梭形或多发结节性低密度灶,增强扫描后病灶呈环形强化8个,蜂窝状或多环状强化2个;10个病灶中明显强化3个,轻至中度强化7个;病灶边缘或中央见点状或条状钙化3个.累及邻近肝实质2例;伴有少量腹水及后腹膜淋巴结轻度肿大1例.结论:浆膜型肝结核的CT表现有一定的特征,当病灶内发现斑点状或条状钙化或病灶呈多环状强化时结合临床表现及实验室检查可作出提示性诊断.

CT Manifestations of the Serohepatic Type of Hepatic Tuberculosis

Objective:To evaluate the value of CT in the diagnosis of the sero-hepatic type of hepatic tuberculosis.Methods:CT without and with contrast medium administration was performed in 8 cases with the sero-hepatic type of hepatic tuberculosis proved by biopsy,the CT findings were retrospectively analyzed.Results:CT displayed 10 lesions in these 8 cases of the sero-hepatic type tuberculosis,including solitary lesion (n=6) and multiple lesions (n=2).All of the lesions showed spindle or multiple-nodular shape and located at the capsule of the liver.Contrast enhanced CT showed peripheral ring-like enhancement in 8 lesions and multi-locular enhancement in 2 lesions;marked enhancement in 3 lesions and mild or moderate enhancement in 7 lesions.Multiple fleck or linear calcifications were seen in 3 lesions.Involvement of adjacent liver parenchyma was seen in 2 cases.Accompanied minimal ascites and retroperitoneal adenopathy were revealed in 1 case. Conclusion:CT characteristics of the sero-hepatic type of hepatic tuberculosis included fleck or linear calcifications within the lesions or multilocular enhancement,the clinical and laboratory findings provided important supplemental information for the diagnosis.
