Small intestinal angiolipoma: MR imaging appearance.
We report the magnetic resonance imaging finding in a case of small intestinal angiolipoma. Small bowel enteroclysis showed a well-defined, lobulated polypoid lesion in the proximal ileum. The mass showed central high signal intensity with peripheral iso-signal intensity on T1-weighted in-phase images. The central high signal intensity changed to low signal intensity on T1-weighted out-of-phase images. After contrast injection, the mass had a strong enhancement along the periphery of the lesion on fat-saturated T1-weighted images. Characteristic decreased signal intensity on out-of-phase T1-weighted images and strong enhancement on postcontrast images of the small bowel mass suggest the diagnosis of angiolipoma.
