摘要

肝臟類上皮血管內皮瘤是一種少見的惡性腫瘤，臨床上沒有特殊的症狀，須靠病理切片作診斷。影像上它具有較特殊的表徵。我們報告一病例的影像檢查，包括超音波，電腦斷層，磁振造影，血管攝影和病理切片。病灶主要位在肝臟邊緣，在超音波和電腦斷層上呈現低回音和低密度，打過對比劑後的電腦斷層有邊緣顯影增強現象。在血管攝影上是富血管支配。在磁振造影方面，以T1為主影像是低訊號，並且在打過對比劑後，周圍會有顯影，在以T2為主影像則為高訊號表現。對於位於肝臟邊緣的多發性病灶，若有上述超音波，電腦斷層，磁振造影血管攝影，必須考慮到類上皮血管內皮瘤的可能。

Hepatic epithelioid hemangioendothelima is a rare malignant neoplasm that has nonspecific clinical signs and symptoms and can be difficult to diagnose on the basis of biopsy results. Radiologists may suggest the diagnosis of this slowly progressive neoplasm by recognizing its characteristic radiological features. We collected images including sonography, computed tomography, magnetic resonance imaging, and angiography. A predominently peripheral distribution with hypoechoic pattern was shown on sonogram. The lesion was low attenuation on CT, and hypervascular on angiogram. On MRI, tumor signal was low on Ti- weighted image with enhanced rim after gadolinium injection and high on T2-weighted image.
