Fig 1. A, Initial CT scan through the basal ganglia shows a cyst (white arrow) and foci of calcifications (black arrows). Note also hypodensity of the white matter.
B, T2-weighted MR image through the basal ganglia shows the cysts (thin arrow), calcifications (hollow arrows), and the surrounding edema (thick arrows).
C, T2-weighted MR image through the cerebral peduncles shows the cysts (thin arrow) and the surrounding edema (thick arrows).
