Headaches, ventricular shunt, hydrocephalus, and prior resection of a colloid cyst. There are postoperative findings related to right transfrontal resection of a colloid cyst with susceptibility from chronic blood products along the surgical approach, but no evidence of colloid cyst recurrence. There is a right transparietal ventricular catheter that termites in the posterior left lateral ventricle. The lateral ventricles remain disproportionately dilated with respect to the rest of the ventricular system. The brain parenchymal signal is otherwise unremarkable and there is no evidence of acute infarct. There is no midline shift or herniation. The major cerebral flow voids are intact. The orbits are grossly unremarkable.
1. Persistent disproportionate dilatation of the shunted lateral ventricles. 2. No evidence of recurrent colloid cyst.
