Atypical primary pulmonary meningioma: A report of a case suspected of being a lung metastasis

Primary extracranial and extraspinal meningiomas are very rare tumours, and primary pulmonary ones are even more uncommon. They present as a solitary pulmonary nodule, and most of them are benign, except for three cases. We describe a primitive atypical pulmonary meningioma first suspected of being a metastasis in a patient during follow-up ten years after therapy for breast cancer. © the authors; licensee ecancermedicalscience.
