History of brain biopsy, third ventricle and removal of EVD 3/31. Evaluate ventricles. Interval removal of right-sided ventricular catheter. A defect in the right calvarium from prior catheter placement is noted. There is stable enlargement of the lateral, third and fourth ventricles. The previously described mass in the pineal gland is of increased attenuation and measures 2.4 x 2 cm (image 13/36, series 2). When accounting for differences in technique, there is no significant change compared to the prior MRI. Calcification is seen along the superior and left anterolateral aspect of the mass.No evidence of intracranial hemorrhage or edema. No midline shift.The visualized paranasal sinuses and mastoid air cells are normally pneumatized.
Pineal region mass with associated hydrocephalus. Size of ventricles appears stable compared to the prior MRI.
