Pilar cyst near cranial suture just left of midline. Does cyst communicate through suture? Brain or eye involvement? Subjective complaints of "my eyes hurt". Brain: There is a well-defined, partially enhancing, low T1 and T2 signal mass in the left apical scalp that measures 20 mm. There are multiple other punctate low signal foci within the scalp diffusely. There is no evidence of intracranial hemorrhage, mass, or acute infarct. The brain parenchyma and pituitary gland appear unremarkable. There is no abnormal intracranial enhancement. 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. There is mild scattered paranasal sinus mucosal thickening.Orbits: The bilateral globes and ocular adnexa are unremarkable. There is no evidence of abnormal intraorbital enhancement or mass lesions.
1. A left apical scalp mass, as well as multiple other punctate low signal foci within the scalp diffusely, may represent pilomatrixomas or related skin adnexal lesions, without evidence of skull erosion or intracranial extension.2. The orbits are unremarkable.
