ABSTRACT
The patient, a 57-year-old man, had undergone repeated tumor resection for local recurrence of meningioma (WHO grade 2), but his disease had progressed. He was brought to the emergency room of our hospital due to dyspnea, was admitted with a large left pleural effusion and bilateral pleural masses, and underwent thoracic drainage. Although there were no malignant findings on pleural fluid cytology, percutaneous needle biopsy of the pleural mass revealed pleural metastasis from meningioma, and the patient was discharged after pleurodesis. This case suggests that pleural metastasis can be observed even in patients without malignant meningioma (WHO grade 3) and that pleural fluid cytology may not diagnose metastatic meningioma to the pleura. In addition, pleurodesis may be helpful for pleural effusion associated with metastatic meningioma to the pleura.
