我们提出了一个硬化性血管瘤（SH）的肝脏，表现出高表观扩散系数（ADC）值的情况下。患者正在接受转移性乳腺癌病变的术前评估时，发现了一个直径为3 cm的肝脏肿块，超声检查显示为不均匀高回声肿块，计算机断层扫描显示为边界清晰的分叶肿块，早期外周增强，延迟期内部不均匀增强。脂肪抑制的T2加权像显示一个不均匀的高信号肿块，ADC值为2.01 x 10 - 3 mm 2/s。影像学检查不能排除肝转移及胆管细胞癌。手术后，获得了SH的明确诊断。显微镜下可见肿瘤内大量玻璃样变，细胞和纤维成分少，玻璃样变伴有液体样变性，这可能是ADC值高的原因之一。我们讨论扩散加权成像的诊断价值的SH的肝脏。
We present a case of a sclerosed hemangioma (SH) of the liver that showed a high apparent diffusion coefficient (ADC) value. The patient was undergoing preoperative evaluation for a metastatic breast cancer lesion when a liver mass with a diameter of 3 cm was found. It was described as a heterogeneously hyperechoic mass on ultrasonography and as a well-defined, lobulated mass with early peripheral enhancement and internal heterogeneous enhancement in the delayed phase on computed tomography. The fat-suppressed T2-weighted images demonstrated a heterogeneously hyperintense mass, which showed an ADC value of 2.01 x 10(-3) mm(2)/s. Liver metastasis and cholangiocellular carcinoma could not be excluded based on the imaging findings. After surgery, a definite diagnosis of SH was obtained. Microscopically, many hyalinized portions with poor cellular and fibrous components were observed in the tumor, and this hyalinization accompanied with liquiform degeneration, which may have been one of the causes of the high ADC value. We discuss the diagnostic value of diffusion-weighted imaging for SH of the liver.
