FDG PET/CT in Dendritic Fibromyxolipoma of the Thigh.

ABSTRACT

ABSTRACT Dendritic fibromyxolipoma is a rare recently described benign soft tissue tumor, which may be misinterpreted histologically as myxoid liposarcoma or myxoid malignant fibrous histiocytoma. We describe FDG PET/CT and MRI findings of a dendritic fibromyxolipoma incidentally detected in a case with rectal adenocarcinoma. The dendritic fibromyxolipoma showed inhomogeneous FDG uptake with SUVmax of 4.0 mimicking malignancy.
