Combined Transarterial Embolization and Surgical Excision of an Oral Intramuscular Hemangioma: A Case Report

Intramuscular hemangioma (IMH) is usually found in skeletal muscles of the trunk or limbs. There is about 10 to 15% occurring in the head and neck region, usually involving the masseter muscle. We present a patient with IMH showing in the left buccal cheek. A healthy 33-year-old male was referred for the evaluation and management of a swelling, purplish-red buccal mass. Preoperative magnetic resonance imaging (MRI) showed a vascular tumor in the left cheek adjacent to the buccinator muscle. Angiography was applied to determine the tumor feeding vessel and preoperative transarterial embolization of the lesion facilitated subsequent surgical treatment by reducing intraoperative blood loss. Intraoral removal of the lesion was performed, and the patient recovered well after operation.

肌內血管瘤好發在軀幹或四肢。頭頸部的病灶僅佔10%到15%且主要發生在咀嚼肌中。本病例報告為一名33歲的男性，此次被轉診評估左側頰部腫脹的紫紅色腫塊。術前磁振造影顯示左側頰肌的血管瘤。經血管攝影檢查確定腫瘤的位置及血管分布後，於術前進行經動脈栓塞，減少腫瘤血液供應降低術中出血。此病患後續接受手術，經由口腔內切除病灶，術後恢復良好。
