Angioleiomyomas are benign solitary smooth muscle tumors originating in the tunica media of vessels. They are rarely encountered within the oral cavity, and the number of reported cases specifically involving the hard palate remains small. A 39-year-old man presented with a 2-cm painless swelling on the left anterior hard palate. The mass had been present for similar to 5 years before presentation, during which time it had slowly enlarged. Magnetic resonance imaging (MRI) showed a uniform signal pattern with T1 signal intensity slightly higher than surrounding soft tissues and marked hyperintensity on T2-weighted sequences. Although the MRI characteristics of angioleiomyomas affecting the extremities have previously been reported, this is the first reported case describing the MRI features of an oral-cavity angioleiomyoma. In view of the inability to differentiate angioleiomyoma from other pathologies with similar MRI features, simple local excision for definitive histopathologic diagnosis remains recommended.
