Answer

Neurofibromatosis

The most serious complication of neurofibromatosis type 1 (NF-1) is optic nerve and/or chiasm glioma (in 15% of patients).

An MRI of the orbit and brain is needed to screen for the tumor.

Sturge-Weber syndrome

In Sturge-Weber syndrome, calcium deposits located predominantly in the occipital lobe of the brain parenchyma can be detected by a CT scan. These deposits follow the cerebral convolutions and give the appearance of a railroad track.

Angiomatous malformations, decreased cerebral volume, and increased choroidal plexus volume are the other findings of Sturge-Weber syndrome. An MRI can delineate these findings better than a CT scan.
