Imaging Features of Sclerosed Hemangioma

Abstract

In our series, suggestive features of sclerosed hemangiomas include geographic outline, capsular retraction, decrease in size over time, and loss of previously seen regions of enhancement. Additional features include presence of transient hepatic attenuation difference (THAD), rim enhancement, and nodular regions of intense enhancement as seen in typical hemangiomas. Although not pathognomonic, some features of sclerosed hemangioma can suggest it as a diagnostic possibility and lead to biopsy rather than more extensive intervention.
