 There is am extra-axial T2 hyperintense area in the right pineal cistern that measures 5 mm in width, but otherwise no evidence of intracranial hemorrhage, mass, or acute infarct. The brain parenchyma and pituitary gland appear unremarkable. 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, and scalp soft tissues are grossly unremarkable. There is a right maxillary sinus retention cyst and mucosal thickening in the right sphenoid sinus.
1. No evidence of acute intracranial hemorrhage, mass, or acute infarct.2. An extra-axial lesion in the right pineal region that measures up to 5 mm in width may represent a cystic structure, but is incompletely characterized. Follow up via MRI with contrast and DRIVE/FIESTA sequences may be useful.3. Right sided inflammatory paranasal sinus disease.
