A 55-year-old female was admitted to our hospital because of the increase in the size of a left posterior mediastinal tumor after 5 years of observation. The patient also had a chest wall tumor on her left back which had 20 year's history. CT findings suggested the mediastinal tumor and the chest wall tumor were connected through the 4th intercostal space. Pathological specimen obtained by a needle biopsy of the chest wall tumor showed neurilemmoma-like lesion, but malignancy could not be ruled out. With a left posterolateral thoracotomy we removed the mediastinal tumor measuring 3 x 2.5 x 2.5 cm and the extra-thoracic chest wall tumor measuring 7 x 3.5 x 3.5 cm. Intra-operative findings showed these tumors arising from the 4 th intercostal nerve separately had no relevancy. Histological examination of both tumors revealed benign neurilemmoma. Postoperative clinical course was uneventful.
一名55岁女性因左侧后纵隔肿瘤在观察5年后体积增大而入院。该患者左背部还有一个有20年病史的胸壁肿瘤。CT检查结果提示纵隔肿瘤与胸壁肿瘤通过第4肋间间隙相连。经胸壁肿瘤穿刺活检获得的病理标本显示为神经鞘瘤样病变，但不能排除恶性可能。我们通过左后外侧开胸术切除了一个大小为3×2.5×2.5厘米的纵隔肿瘤和一个大小为7×3.5×3.5厘米的胸壁外肿瘤。术中发现这两个分别起源于第4肋间神经的肿瘤并无关联。对这两个肿瘤的组织学检查均显示为良性神经鞘瘤。术后临床过程平稳。
