Angiomyolipoma of the liver: ferumoxides-enhanced MR imaging

Eur Radiol. 2000;10(9):1401-3. doi: 10.1007/s003300000355.

Abstract

We report a case of angiomyolipoma of the liver with emphasis on the appearance at MRI after administration of ferumoxides. Post-contrast T1- and T2-weighted images showed a frank decrease of signal intensity in a rim on the margin of the tumor. This unusual finding was related to the presence of an increased number of CD68-positive histiocytic cells in the periphery of the lesion and in the adjacent liver parenchyma.
