chronic headache, old history of pituitary tumor. No evidence of acute ischemic or hemorrhagic lesion.The ventricles, sulci and cisterns are symmetric and unremarkable.There is no mass, mass effect, edema, midline shift, intra or extra-axial fluid collection/hemorrhage, restricted diffusion/acute ischemia, or abnormal contrast enhancement. Although this study is not a dedicated study for pituitary gland, the left side pituitary gland appears to be resected and does not show enhancement on post Gad study.The midline structures and cranial-cervical junction are normal. Normal flow voids are identified in the major intracranial vessels. The mastoid air cells are clear.Bilateral maxillary sinuses show retention cysts.3D time of flight MOTSA MRA brain images with maximum intensity projections of the anterior/posterior intracranial circulation demonstrate normal ICAs, MCAs and ACAs. Vertebrobasilar system appears to be normal.
1. No evidence of acute ischemic or hemorrhagic lesion. No abnormal enhancement.2. Post left pituitary gland resection status. 3. No evidence of intracranial arterial aneurysm, or arterial stenosis.
