摘要

肝臟海綿狀血管瘤是最常見的肝臟良性腫瘤，其典型的核磁共振影像呈現結節性顯影及延遲充填在T1-weighted imaging，而在T2-weighted imaging則提供高亮度表現，讓我們更易於診斷，然而當一個腫瘤在T2-weighted imaging無高亮度的表現，要下血管瘤的診斷就非常困難。硬化性血管瘤是一種罕見的非典型血管瘤，其困難點就在於無法用影像作一確切診斷。我們在這裡提出一個女性病患合併輕微黃疸，因意外發現肝腫瘤，且無法以超音波，電腦斷層及腫瘤指標作一有效判斷，核磁共振又無法排除膽管癌的可能性，最後安排術中切片證實為硬化性血管瘤。

Cavernous hemangioma is the most common benign hepatic tumor. The typical magnetic resonance imaging (MRI) shows nodule enhancement and delayed filled-in during T1-weighted imaging. Hyperintensity in T2-weighted imaging provides sufficient evidence for the diagnosis typical hemangioma. If, however, the signal intensity of T2-weighted imaging is not very high, hemangioma usually escapes correct diagnosis. Sclerosed hemangioma is a rare atypical hemangioma, and its diagnosis with medical imaging alone is difficult. Here we present a case of a female patient who was incidentally found to have a hepatic tumor with unknown etiology after sonography, computed tomography and tumor marker survey. Cholangiocarcinoma was suspected because of MRI findings and mild hyperbilirubinema. Finally, surgical biopsy provided the direct evidence of sclerosed hemangioma.
