Intramuscular lipomas are benign tumors that infiltrate the muscles.
We describe the case of a 58-year-old female patient with an axillary lump. The lump was a lipoma inside the subscapularis muscle. It is important to differentiate these lesions from liposarcomas and from other diseases that may present as axillary lumps. The most accurate imaging method for differentiating benign lipomatous tumors from liposarcomas is magnetic resonance imaging, but surgical removal of these intramuscular lesions to confirm the diagnosis is recommended.
Intramuscular lipomas are a rare cause of benign axillary lumps and should be considered in making differential diagnoses on axillary masses.
肌内脂肪瘤是浸润肌肉的良性肿瘤。
我们描述了一名58岁女性患者腋窝肿块的病例。该肿块是肩胛下肌内的脂肪瘤。将这些病变与脂肪肉瘤以及可能表现为腋窝肿块的其他疾病区分开来很重要。鉴别良性脂肪瘤性肿瘤与脂肪肉瘤最准确的成像方法是磁共振成像，但建议手术切除这些肌内病变以确诊。
肌内脂肪瘤是腋窝良性肿块的罕见病因，在对腋窝肿块进行鉴别诊断时应予以考虑。
