RESUMO
Giant hepatic artery aneurysm is a very rare vascular lesion, but can be detected incidentally during abdominal imaging. We report the sonographic and computed tomography (CT) features of a giant hepatic artery aneurysm in a 52-year-old woman presenting with vague abdominal discomfort. This report illustrates that a giant hepatic artery aneurysm can manifest as an incidental large mass in the porta hepatis, and we discuss the role of sonography and CT in the diagnosis of the lesion and review the natural history and clinical presentation of hepatic artery aneurysm.

In this study, we evaluated MR imaging findings of skin tumors and categorized them into four types: (1) discrete mass lesions of the dermis and epidermis, (2) mass lesions of the subcutis with or without abutment to the skin, (3) diffuse or localized skin thickening without a true mass, and (4) a skin mass with bone destruction. The categorization of MR images may be useful in the differential diagnosis of skin tumors.
