12-year-old girl with pineal abnormality, follow-up scan. There is artifact in the maxillofacial region, presumably possibly to braces, which limits evaluation of portions of the brain on some sequences. There is redemonstration of complex appearing multicystic lesion in the pineal region, with focal enhancement along the posterior aspect which may represent normal pineal tissue. The lesion again measures 9 mm transverse by 13 mm AP by 9 mm CC, essentially unchanged since baseline exam. There is again minimal if any flattening of the tectal plate; the cerebral aqueduct remains open. The brain parenchyma is grossly unremarkable within the limitations of artifact. The ventricles are normal in size and configuration.
Stable mildly complex pineal cyst dating back to 3/2/2012.
