Meningioma is a common brain tumor but despite its high prevalence, extracranial metastasis is really rare, as it may be seen in lung, bone, intraspinal, liver and cervical lymph nodes decreasingly. We report a case of metastases to lung incidentally founded from an intracranial recurrent atypical meningioma with superior sagittal sinus invasion previously treated with good control. This report highlights that in the rare case of unique incidentally founded pulmonary lesion and apparent control of the intracranial disease, the differential diagnosis of metastastic meningioma, primary lung meningioma or others lung tumor can be very challenging . The revision of pertinent literature suggests that the invasion of venous sinuses should be considered as a major risk factor for distant metastases.
