| Abstract: | Intramuscular hemangiomas make up less than 1% of all hemangiomas 1]. These invasive and aggressive lesions appear to have a predilection for large muscle masses. They can be strikingly aggressive in the head and neck, and persistence despite radical treatment is common. Spontaneous resolution in adults to our knowledge has not been reported in the literature. We present a case report of an invasive intramuscular hemangioma involving the parotid gland, the masseter and pterygoid muscles, and the infratemporal fossa after local resection of an apparently isolated lesion of the lip and the submandibular triangle. We describe a detailed course of treatment and review the literature. |
