title: Is a benign meningioma always an indolent tumor?
abstract: Meningiomas are considered to be slow-growing tumors that compress the brain without invading it. The development of metastases is uncommon, with a predilection for the lungs, liver, lymph nodes, and bone. We report the case of a 58-year-old man, diagnosed with a solitary pulmonary nodule in the left lower lobe that was resected through a thoracotomy. The pathology revealed lung metastases of an undiagnosed meningothelial meningioma. The evolution of the patient's case, the second case in the literature of this kind of benign tumor that has developed pleural metastases, was unsatisfactory.
