Planum sphenoidale/tuberculum sellae meningioma. A 39-year-old-male presented with headaches, visual disturbances, and papilledema. A (coronal) and B (sagittal), T1-weighted MRIs with gadolinium show a large planum sphenoidale/tuberculum sellae meningioma with mass effect on both frontal lobes. The tumor is deforming the third ventricle, causing hydrocephalus. Also notice that both anterior cerebral arteries are stretched and deformed (A, arrows) by the tumor mass. The patient underwent a subfrontal craniotomy and interhemispheric approach for tumor resection. During the microsurgical resection, part of the tumor was extremely adhered to the roof of the third ventricle and fornices. This part of the tumor was not resected. C (coronal) and D (sagittal), postoperative MRIs show almost complete gross total resection. The patient will be managed conservatively with serial imaging.
