Pineal cyst with headaches, evaluate for changes: follow up. There is a pineal gland cyst that measures up to 20 mm, with a small amount of susceptibility effect, which may represent chronic blood products. There is no evidence of intracranial hemorrhage or acute infarct. There is a fine surgical tract in the right frontal lobe. The cerebral parenchyma, brainstem, cerebellum, and pituitary gland otherwise appear unremarkable. There is no abnormal intracranial enhancement. There are a few unchanged scattered foci of intraventricular susceptibility effect. 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, including a right fetal PCA. The orbits, skull, paranasal sinuses, and scalp soft tissues are grossly unremarkable.
Unchanged pineal cyst and post-surgical findings without associated hydrocephalus.
