A case of lung metastasis of meningioma associated with primary lung cancer

Abstract

A 66-year-old woman was referred to the hospital for the purpose of receiving close exploration of an abnormal shadow in the hilar region of the right lung in a chest X-ray film. A chest CT scan showed a mass with the diameter of 4 cm in S⁶ of the right lung as well as a nodular shadow with the diameter of 5 mm in the S¹⁰. Adenocarcinoma was diagnosed with the bronchoscopic biopsy and cytology from the right B⁶. Meningioma was suspected by preoperative head CT scan, however, we considered that the presence might not disturb surgery for the lung lesions. We performed right lower lobectomy and lymphadenectomy (ND2a). The postoperative pathological diagnosis of the S⁶ lesion was adenocarcinoma, but that of the nodule of the S¹⁰ was meningioma. We judged that the cephalic meningioma did not require surgery. The patient received postoperative adjuvant chemotherapy for lung cancer, but died of cancer one year and two months after the operation.
This case is considered to be extremely rare in that metastasis of meningioma was concomitantly present in the same lobe of the lung from where primary lung cancer had arisen.
