We describe a case of angioleiomyoma in the buccal space, and discuss its magnetic resonance imaging (MRI) features with histopathological correlation, with particular emphasis on the usefulness of using dynamic contrast-enhanced MRI (DCE-MRI) to differentiate other possible tumors. Angioleiomyoma of the buccal space in this case corresponded clinically and histopathologically to the previous reports. The characteristic findings of angioleiomyoma were a very high signal intensity on T2WI, and extremely high enhancement on Gd-T1WI. The inner aspect of this lesion was homogeneous on both T1WI and T2WI. However, the histopathological findings included tumor substance, mucous degeneration, and mature adipose cells, and these findings were reflected only on the DCE-MRI. Furthermore, the CI-Curve of the angioleiomyoma showed a characteristic pattern, which might differentiate it from other tumors.
