Abstract
Hemangioma is the most common benign tumor in neonatal and infant stage. In the head and neck region, the lesion mostly occurs in the masseter, trapezoidal or sternocleidomastoid muscle. Due to its rarity and non-specific symptoms, it is difficult to diagnose precisely. Intramuscular hemangioma can be misdiagnosed as sialolithiasis of the parotid gland. There are several treatment options for hemangiomas such as sclerotherapy, radiotherapy, embolization, and surgery. Of all these, definitive surgical resection is considered most effective in preventing future recurrence. Here we report a case of intramuscular hemangioma that was detected in the patient's right masseter muscle which was initially misdiagnosed as parotid sialolithiasis and was consequently managed with surgical resection.
