title: An Intramuscular Hemangioma at the Cervical Muscle: A Case Report.
abstract: Intramuscular hemangioma (IMH) primarily develops in the skeletal muscles of the limbs or trunk. The occurrence of IMH in the neck muscle is very rare. In the present report, we describe a case of IMH in the posterior neck muscle. A 58-year-old woman presented with a mass on the right posterior neck area, which had developed 2 years previously. The tumor was round in shape, had a size of 3.5×3.0 cm, and was fixed to the surrounding soft tissue. The patient complained of mild dull pain and tenderness at the mass without reddish discoloration. The mass showed a diurnal variation in size - the mass grew in size in the morning and became smaller in the afternoon. Preoperative study confirmed the vascular nature of the tumor. During peritumoral dissection, the mass shrank rapidly following profuse bleeding and arterial cauterization, and hence, it was difficult to distinguish the mass from the surrounding tissues. A total resection was possible with careful dissection of its fibrotic boundary. Based on the histological findings, a definitive diagnosis of cavernous type IMH was made. An initial suspicion of IMH, according to the clinical findings, would be helpful for decision making of further evaluations and surgical plan.
