Intractable headache (occipital). There is no evidence of intracranial hemorrhage, mass, or acute infarct. There is patchy and scattered cerebral white matter T2 hyperintensity, which is most pronounced in the bilateral posterior periventricular regions. There is no abnormal intracranial enhancement. There are bilateral small lateral ventricular choroid plexus glomus xanthogranulomas. The ventricles and basal cisterns are otherwise 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. There is an apparent small right parotid lesion that is only depicted on the coronal T2-weighted sequence. There is a subcentimeter incisive duct cyst.
1. Probable chronic small vessel ischemia, but no evidence of intracranial hemorrhage, mass, or acute infarct. 2. Incompletely imaged apparent small right parotid lesion. An ultrasound of this region may be useful for further evaluation.
