A 61-year-old woman was referred to our clinic because of an abnormal shadow in the left lower lung field on an X-ray taken at a regular checkup. She had no subjective symptoms. Past history included myoma uteri at 47 yr and iatrogenic left pneumothorax subsequent to acupuncture for muscle pain in the shoulder. On CT, a solitary round lesion 2.5 cm in diameter and smooth margin was located at S5 just below the visceral pleura. Since we were unable to obtain a histological diagnosis by bronchofiberscopy, thoracotomy was carried out and the lesion was resected. The intraoperative pathological diagnosis was a benign lesion resembling leiomyoma. After surgery, re-evaluation of the myoma uteri specimen resected 14 years previously was done, as well as desmin immunohistochemical staining of the lung lesion, which demonstrated no evidence of a smooth muscle component in the latter. The final diagnosis was inflammatory pseudotumor.
一名61岁女性因定期体检时胸部X线显示左下肺野异常阴影而转诊至我院。她无主观症状。既往史包括47岁时患子宫肌瘤，以及因肩部肌肉疼痛行针灸治疗后发生医源性左侧气胸。胸部CT显示，在S5水平、脏层胸膜下方有一个直径2.5 cm、边界光滑的孤立圆形病灶。由于经纤维支气管镜检查无法获得组织学诊断，遂行开胸手术并切除病灶。术中病理诊断为类似平滑肌瘤的良性病变。术后，对14年前切除的子宫肌瘤标本进行了重新评估，并对肺部病灶进行了结蛋白免疫组化染色，结果显示后者无平滑肌成分。最终诊断为炎性假瘤。
