Intramuscular hemangiomas of the head and, neck are rare congenital vascular tumors and are sparsely reported. Hemangiomas account for approximately 7% of benign tumors and usually present as a mass that suddenly enlarges. Hemangiomas are mostly seen on the trunk and extremities, but can also appear on the head and neck region. A 10-year-old boy was referred to our clinic for puffiness and swelling on the right side of his neck. Neurological examination was normal, but we observed an advanced degree of restriction in neck movement. An MRI study showed a soft tissue mass 9x8x5 in size. The mass was totally extracted by surgical intervention and pathological analysis revealed that it was a cavernous hemangioma. The patient's neck movement returned to normal after surgery. No relapse occurred during 1-year follow-up.
