Headache and history of pseudotumor cerebri. MRI: The images are partially degraded by dental brace artifact. There is no definite evidence of intracranial hemorrhage, mass, or acute infarct. The brain parenchyma appears grossly unremarkable. The pituitary gland appears unchanged, with a partially-empty sella configuration. There is no abnormal intracranial enhancement. The ventricles and basal cisterns are normal in size and configuration. There is no midline shift or herniation. MRA: The images are partially degraded by dental brace artifact. There is an unchanged 2 mm outpouching in the region of the right ACOM complex at the origin of the orbitofrontal artery. There is no discernible evidence of significant steno-occlusive lesions.
1. No definite evidence of acute intracranial hemorrhage, mass, or acute infarct, although the images are partially degraded by dental brace artifact. 2. Unchanged partially-empty sella suggestive of pseudotumor cerebri.3. Unchanged 2 mm outpouching in the region of the right ACOM complex, which may represent a prominent infundibulum or small aneurysm.
