Tuberous sclerosis with an atypical radiological skull change: case report.

The authors describe a case of tuberous sclerosis with atypical radiological skull change in a 8-year-old Japanese child. A plain roentgenogram showed thinning and convolution of the left occipital bone, and a cortical tuber adjacent to the thinned bone was shown by computed tomography. This kind of skull change may suggest the existence of a cortical tuber in patients with tuberous sclerosis, although this finding has not been reported previously. The mechanism of this skull change is discussed.
