Abstract

OBJECTIVE: To describe the MR imaging features of hepatic hemangioma with perilesional enhancement. MATERIALS AND METHODS: A search was performed of the MRI section database to identify all cases of hepatic hemangioma with perilesional enhancement between March 2008 and July 2009. All patients underwent MR examinations including precontrast T1- and T2-weighted images and postgadolinium dynamic images. On MR images, characteristics of the hemangioma and perilesional enhancement were evaluated. RESULTS: Seven hemangiomas in seven patients (five men, two women; age range, 41-69 years; mean, 57 years) were included in this study. Lesion size ranged from 7 to 20 mm (mean, 12.4 mm). On hepatic arterial dominant phase, all seven hemangiomas exhibited wedge-shaped perilesional enhancement which faded on two minutes postgadolinium images. Four of these lesions demonstrated adjacent capsular enhancement. CONCLUSION: All hepatic hemangiomas with perilesional enhancement were < 2 cm capsulebased lesions. This location suggests that these hemangiomas may conscript capsular vessels to account for the perilesional enhancement.
