Intramuscular lipoma is a rare benign mesenchymal tumor that infiltrates the skeletal muscle. These lipomas are usually found on the extremity, but rarely occur in the head and neck. To our knowledge, only 4 cases of intramuscular lipoma in the sternocleidomastoid muscle have been reported in the literature. The recurrence rate of intramuscular lipoma is high, and it shows the pattern of infiltration to tissues, and thus different from general lipomas, its resection should include adjacent normal muscular tissues. In addition, although rare, concerning intramuscular lipoma that developed in the head and neck area, because important structures are present densely in a small space, it is important to establish a preoperative plan by determining the size and location of the tumor through preoperative clinical and radiologic tests. We had a case of intramuscular lipoma in sternocleidomastoid muscle and resected the mass completely including a portion of attached muscles. The postoperative course was uneventful, and no evidence of recurrence occurred after 6 months of follow-up.
肌内脂肪瘤是一种罕见的良性间叶组织肿瘤，可浸润骨骼肌。这些脂肪瘤通常见于四肢，但很少发生于头颈部。据我们所知，文献中仅报道了4例胸锁乳突肌内的肌内脂肪瘤。肌内脂肪瘤的复发率较高，呈浸润性生长模式，与一般脂肪瘤不同，其切除应包括相邻的正常肌肉组织。此外，虽然罕见，但对于发生在头颈部区域的肌内脂肪瘤，由于重要结构密集分布于狭小空间内，通过术前临床和影像学检查确定肿瘤的大小和位置以制定术前计划很重要。我们有1例胸锁乳突肌内肌内脂肪瘤患者，完整切除了肿块及部分附着肌肉。术后恢复顺利，随访6个月无复发迹象。
