Ovarian cancer screening for clinical trial: fatigue. There is no evidence of intracranial hemorrhage, enhancing mass, or acute infarct. There is an arachnoid cyst in the right middle cranial fossa with extension to the Sylvian fissure and associated mass effect upon the adjacent temporal and frontal lobes. There is mild scattered nonspecific cerebral white matter T2 hyperintensity, mainly in a periventricular distribution. The ventricles and basal cisterns are normal in size and configuration. There is no midline shift or herniation. The major cerebral flow voids are intact. The orbits, skull, paranasal sinuses, and scalp soft tissues are grossly unremarkable.
1. No evidence of intracranial metastases. 2. Right middle cranial fossa arachnoid cyst with extension to the Sylvian fissure and associated mass effect upon the adjacent temporal and frontal lobes.
