Intramuscular hemangiomas are rare benign vascular neoplasms. IMH accounts for less than 1% of all hemangiomas. These neoplasms commonly occur in trunk and extremities but are rare in head and neck region. The present case is a 17-year-old female patient, who presented with a painless, slowly enlarging mass in left sided upper neck for 4 years. Investigations were suggestive of vascular neoplasm. She underwent excision of the mass in toto under general anesthesia. Postoperative period was uneventful. Histopathological examination of the mass revealed it as mixed type of intramuscular hemangioma. She did not have any signs of recurrences on her last follow-up at 6 months postoperatively. This case report discusses the rare IMH arising from thyrohyoid strap muscle.
肌内血管瘤是一种罕见的良性血管肿瘤。肌内血管瘤占所有血管瘤的比例不到1%。这些肿瘤通常发生于躯干和四肢，但在头颈部区域较为罕见。本病例为一名17岁女性患者，左侧上颈部出现无痛性、缓慢增大的肿块4年。检查提示为血管肿瘤。她在全身麻醉下接受了肿块的完整切除。术后恢复顺利。肿块的组织病理学检查显示为混合型肌内血管瘤。术后6个月的最后一次随访时，她没有任何复发迹象。本病例报告讨论了起源于甲状舌骨肌束的罕见肌内血管瘤。
