Computerized Axial Tomography in Family Members of Patients with Tuberous Sclerosis

The diagnosis of unsuspected TS has been reached with the aid of computerized axial tomography. Most cases are sporadic, but incomplete forms of the disease may be difficult to detect. We have, therefore, studied nine immediate family members of four cases with TS. The results were negative in all of them, confirming the earlier notions that, in the absence of adenoma sebaceum in either parent, the disease is most probably sporadic.
