Rarely do rhabdomyomas occur in multiple sites. We describe the magnetic resonance (MR) imaging appearance of multiple adult rhabdomyomas synchronously involving the floor of the mouth, base of the tongue, and oropharynx in a 70-year-old man.

Rhabdomyomas are rare, benign lesions that account for only 2% of all primary skeletal muscle neoplasms.¹ They usually involve the myocardium and, based on histology, are divided into fetal and adult forms. Ninety percent of extracardiac tumors occur in the head and neck.¹ Whether all rhabdomyomas are true neoplasms or hamartomas is not clear, but some studies have suggested that the adult form is a true neoplasm. Approximately 3% to 10% of adult rhabdomyomas may be multiple and either synchronous or . . . [Full Text of this Article]
