摘要
The imaging features of an atypically enhanced hepatic hemangioma have not been well described in the literature, and the presence of such atypia may sometimes cause clinical problems in the differential diagnosis. Herein, we report a case of hepatic hemangioma demonstrating a previously unreported atypical enhancement pattern. On dynamic computed tomography during hepatic arteriography, a centrifugal enhancement pattern and subsequent peritumoral ring-shaped enhancement mimicking corona enhancement were found in cavernous hemangiomas of the liver in a 68-year-old Japanese man. Histopathological diagnosis of cavernous hemangioma of the liver was made on a biopsy specimen. Considering the importance of differentiating benign hepatic tumor from various forms of malignancy, radiologists and hepatologists should be aware of rare enhancement patterns sometimes seen in hepatic hemangioma. Establishing knowledge of the entire spectrum of atypical hepatic hemangioma may benefit the rational approach to future cases.
