Skull radiographs may show the classic double-lined gyriform pattern of calcifications paralleling cerebral convolutions referred to as “tram-track” (also called tramline, trolley-track, or railroad track) calcifications. These were considered pathognomonic for SWS in the era prior to modern neuroimaging, but they are often a late finding and may not be present initially.

Wilms et al reported tram-track calcifications in tuberous sclerosis with calcification located in extensive cortical tubers [59] ; Borns and Rancier reported these in childhood leukemia. [60]
