Fibrolipoma is a benign tumor variant of lipoma. Fibrolipomas of the oral cavity are rare. They are more frequent in males than in females, built mostly of fibrous connective tissue. Magnetic resonance imaging (MRI) findings of oral lipomas have previously been described; however, no report on MRI of oral fibrolipomas is available in the literature. This paper reports the MRI features of a large, pedunculated oral fibrolipoma in an adult patient. Unlike oral lipomas, the fibrolipoma was inhomogeneously hyperintense on both T1 and T2-weighted sequences, and revealed a moderate, inhomogeneous contrast enhancement. MRI was also useful to evaluate the region of attachment of the peduncle excluding an infiltrative component.
