Abstract

Intramuscular haemangiomas (IH) are rare lesions, accounting for less than 1% of all haemangiomas. This article presents the case of a woman in her 40s with a swelling in her left cheek. CT revealed an intramuscular lesion within the masseter, suggestive of a venous malformation. Surgical treatment was carried out with intraoral access to the lesion, allowing for complete removal, resulting in temporary swelling and trismus. There was no facial paralysis. We discuss information on IH in the head and neck and their surgical approaches.
