Right craniotomy for subependymal giant cell astrocytoma resection POD 1 in a patient with tuberous sclerosis complex. There are recent postoperative findings related to right foramen of Monro region tumor resection, with crescentic T1 hyperintensity and susceptibility effect in the resection bed, which likely represents blood products, as well as mild surrounding vasogenic edema, but no evidence of gross residual tumor. There is a small amount of hemorrhage in the occipital horns of the lateral ventricles and scattered pneumocephalus. The lateral ventricles are no longer dilated. There is no significant change in the numerous other bilateral lateral ventricular subependymal nodules and appearance of the ventricular system. Likewise, the numerous scattered cortical and subcortical tubers appear unchanged. There is no evidence of acute infarction or hemorrhage. The cerebral flow voids are grossly unremarkable. There are bilateral mastoid effusions. The skull and orbits appear unchanged.
