 Redemonstrated is a primarily T2 hyperintense mass lesion in the parietal lobe containing some central T2 hypointense components. On recent comparison brain MRI this demonstrated ring enhancement with adjacent vasogenic edema. There is no significant associated mass effect. The ventricles are unchanged in size or shape. Expected vascular flow voids are demonstrated. Mucosal thickening is again noted within the right maxillary sinus and a single anterior left ethmoid air cell. The remaining paranasal sinuses and the mastoid air cells are clear.Incidental note is made of a 5 mm transverse x 5 mm AP x 7 mm craniocaudal focus within the posterior sella which is T1 hypointense and T2 hyperintense. This is unchanged when compared to the 2 prior comparison studies. Although not mentioned previously, it is felt to represent a benign entity such as a pars media or Rathke's cleft cyst.
