Imaging Findings of Undifferentiated Embryonal Sarcoma of the Liver in Adults
-
摘要: 目的：探讨成人肝脏未分化胚胎性肉瘤（UESL）的CT/MRI表现及病理对照分析。资料与方法：回顾性分析经手术切除并病理证实的UESL 5例患者临床和影像学资料。结果：5例病灶均单发，4例位于肝右叶，1例同时累及肝左右叶。CT/MRI表现为边界模糊的囊实性肿块，囊壁见结节状、不规则软组织密度/信号影，内见厚壁不均分隔，CT平扫呈低密度，内见大片状液化、坏死，MRI平扫呈长T1长T2信号改变，CT/MRI增强扫描壁结节、软组织成分及囊内分隔呈轻度渐进性强化。结论：成人UESL影像表现有一定的诊断价值，有助于提高术前诊断准确率。

Abstract: Objective: To investigate the CT and MRI features of undifferentiated embryosarcoma(UESL) of the liver in adults. Materials and methods: the clinical and imaging data of 5 patients with ueslwere analyzed retrospectively. Results: the lesions were single in 5 cases, 4 in the right lobe of the liver and 1 in the left and right lobe of the liver. CT/MRI showed a solid mass with fuzzy boundary, nodular and irregular soft tissue density/signal shadow on the wall of the cyst, uneven separation of thick wall, low density on CT plain scan, large liquefaction and necrosis on MRI plain scan, long T1 and long T2 signal changes on MRI plain scan, and slightly progressive enhancement on CT/MRI enhanced scan of wall nodule, soft tissue composition and separation in the cyst. Conclusion: the imaging findings of adult UESL have certain diagnostic value, which is helpful for preoperative diagnosis.-
