Plain films had not been obtained prior to the MRI examination. T1-weighted MRI and T2* GRE showed a bright lesion with sclerotic wall thickening and bony septa. On STIR and fat-suppressed, PD-weighted images, most of the interior signal of the lesion was suppressed, except for some irregular hyperintense inclusions. The lesion showed no signs of aggressive behavior. Intravenous contrast medium was not administered.
