| 目的：观察硬化型肝细胞癌的影像学表现及其特点。方法：对4例经病理学检查证实的硬化型肝细胞癌进行回顾性影像学材料分析。结果：超声检查：3例右叶病灶为边界清晰的均匀低回声肿块, 1例左叶病灶为偏强回声肿块。平扫CT:表现为边界清楚的低密度灶, 内部结构相对均匀, 无肿瘤包膜。2例可见载瘤区局部萎缩。肿瘤未见明显出血、坏死表现。MR检查：表现为均匀的长T1、长T2信号, 边界清楚, 未见肿瘤包膜。DSA检查：1例接受DSA检查者表现为右叶富血性病灶, 有较均匀的肿瘤染色。结论：硬化型HCC是HCC的少见类型。 |

| Purpose:To observe imaging characteristics of sclerosing HCC. Methods:A retrospective study of image findings of 4 cases of sclerosing HCC was performed. All the tumors were pathologically improved, and all patients underwent surgical resection of the tumor. Results:In all 4 cases, precontrast CT showed well circumscribed hypointense tumors. The tumor capsule was not seen in any patients. Focal atrophy in the tumor bearing area was senn in 2 cases. Necrosis, cystic change, or massive hemorrhage was not observed. On MRI, tumors were hypointense on T1WI and hyperintense on T2WI. DSA showed moderate hypervascularity of one tumor. Conclusions:In the presence of liver tumors, homogeneous architecture, hypervascularity, absence of tumor capsule and focal atrophy in high risk patients of HCC, sclerosing HCC should be considered. |
