Intramuscular lipomas (IMLs) are rare benign tumors that arise when lipomas infiltrate muscle tissue. These tumors are most commonly found in the large muscles of the limbs and trunk, particularly in the thigh, shoulder, and upper arm. IMLs often present as painless masses but can cause pain, muscle dysfunction, and neurological deficits as they grow and invade surrounding structures. This case series discusses three patients with IMLs located in uncommon sites: the wrist, foot, and trapezius muscle. Diagnostic imaging, including ultrasound and magnetic resonance imaging (MRI), was essential in identifying and characterizing these lesions. Surgical excision is the treatment of choice, though the infiltrative nature of IMLs increases the risk of recurrence. This series underscores the importance of early diagnosis and appropriate management of IMLs, particularly in rare anatomical locations.
肌内脂肪瘤（IMLs）是一种罕见的良性肿瘤，由脂肪瘤浸润肌肉组织引起。这些肿瘤最常见于四肢和躯干的大肌肉中，尤其是大腿、肩部和上臂。IMLs通常表现为无痛性肿块，但随着它们的生长和侵犯周围结构，可引起疼痛、肌肉功能障碍和神经功能缺损。本病例系列讨论了3例IMLs位于不常见部位的患者：腕部、足部和斜方肌。包括超声和磁共振成像（MRI）在内的诊断性影像学检查对于识别和表征这些病变至关重要。手术切除是首选治疗方法，不过IMLs的浸润性增加了复发风险。本系列强调了IMLs早期诊断和适当管理的重要性，尤其是在罕见的解剖部位。
