A Rare Case of Frontal Lobe Cavernous Malformation Mimicking Meningioma.

Cavernous venous malformations are benign vascular lesions that commonly occur in the brain parenchyma. These when present in the extra-axial or superficial cortical location can be mistaken for meningioma. Magnetic resonance imaging (MRI) can help in the detection and easy differentiation of the two entities and thus aid in preoperative diagnosis and preventing intraoperative complications. We present a case of an 18-year-old male patient suffering from seizures, which was initially diagnosed as meningioma. However, detailed evaluation with MRI raised a possibility of cavernous malformation and it was considered as a differential.
