Marked Enlargement and Post-Op Recurrence of Hepatic Hemangiomas: Two Cases Report

ABSTRACT

Hepatic hemangiomas are the most common benign tumor of the liver, and follow-up radiologic imaging studieshave normally shown no interval change in the diameter of the tumor. Among the very few tumors in which suchchange have been seen, growth has been minimal. However, we experienced some marked enlargement of the tumorfollow-up imaging studies. First, the marked enlargement of the tumor followed by resection, and as a result,hepatic hemangioma was confirmed. Second, hepatic hemangioma was confirmed after resection, but recurred. Tumorenlargement seems to be caused by ectasia of blood-filled cystic space or estrogen stimulation, through we foundno specific etiology.
