The following 3 imaging studies are usually undertaken in patients with TSC:

  • Computed tomography scanning or magnetic resonance imaging of the brain: Performed to identify SEGAs before obstructive hydrocephalus occurs; they also identify the extent and number of cortical tubers present [2]

  • Renal ultrasonography: Performed to assess change in AMLs or cysts, in the hope that this will allow operative intervention prior to the development of renal failure

  • Echocardiography: Performed as part of the baseline evaluation in a patient with newly diagnosed or suspected TSC
