肝脏少见肿瘤多层螺旋CT分析

目的探讨肝脏少见肿瘤的多层螺旋CT征象,提高对肝脏少见肿瘤CT表现的认识。方法回顾性分析经手术及病理组织学证实的9例肝脏少见肿瘤的多层螺旋CT征象及临床资料,并结合文献复习。结果 9例分别为肝间叶性错构瘤2例,肝腺瘤2例,肝恶性间叶瘤2例,肝平滑肌肉瘤2例,肝黏液肉瘤1例。CT表现主要有肝间叶性错构瘤表现为肝囊实性肿块并增强后实性明显强化;肝腺瘤1例表现为明显强化,且有包膜,1例多发;肝恶性间叶瘤表现为囊实性肿块,实性部分中度-明显强化,1例并有多发子灶;肝平滑肌肉瘤表现为平扫低密度,增强后轻度-明显不均匀强化的实性肿块;肝黏液肉瘤表现为巨大低密度囊实性肿块,并不均匀中度强化。结论本组肝脏肿瘤均较少见,大部分病例MSCT表现缺乏特异性,诊断中应结合临床考虑到上述肿瘤的可能,减少误诊。

Multislice CT diagnosis of rare liver tumors

Objective To evaluate the MSCT diagnosis of rare liver tumors.Methods The clinical records and CT findings of 9 patients with rare liver tumors confirmed by pathology were analyzed retrospectively.Results The liver tumors were mesenchymal hamartomas（2）,adenomas（2）,malignant mesenchymomas（2）,leiomyosarcomas（2）and myxosarcoma（1）.The CT features were mixed solid and cystic mass with enhancement of the solid component in mesenchymal hamartoma,enhancing and encapsulated mass （es）in adenoma（s）,moderate to marked enhancement of solid component of mixed cystic and solid mass in malignant mesenchymoma with multiple satellite nodules,hypodense mass with mild to marked enhancement in leiomyosarcoma,heterogeneous moderate enhancement of cystic mass in myxosarcoma.Conclusion The CT features of rare liver tumors are nonspecific and require clinical correlation and biopsy for diagnosis.
