Priamry Pulmonary Meningioma: A Case Reprot / 대한흉부외과학회지

ABSTRACT

Primary pulmonary meningioma is an extremely rare disease. It is mostly benign and asymptomatic. This tumor shows the same cytohigstologic appearance as brain or spinal cord meninioma. It can be diagnosed as a primary pulmonary meningioma only if there is no evidence of metastasis from the brain or spinal cord meningioma. We experienced a case of primary pulmonary meningioma in a 60-year-old woman who had asymptomatic 2 cm-sized solitary pulmonary tumor in the right lower lobe. It is rather peripherally located. Fine needle aspiration cytology has suggested the possibility of either well-differentiated epithelial malignancy such as papillary adenocarcinoma or mucoepidermoid carcinoma or metastatic carcinoma such as from ductal carcinoma of the breast. Right lower lobectomy was performed. The tumor was bilobated and soild with yellowish color. pathologically it proved to be a primary pulmonary and solid with yellowish color. Pathologically it proved to be a primary pulmonary meningioma because there was no evidance of brain or spinal cord tumor. To the best of our knowledge this is the first case reported in Korea. We report this case with review of the literature.
