Overview

CT scans are very useful on diagnosing tuberous sclerosis due to the vast possible findings that patients may present.

CT

CT scan may be helpful in the diagnosis of tuberous sclerosis. It can diagnose:

• Cortical or subependymal tubers;
• White matter abnormalities;
• Subependymal hamartomas;
• Subependymal giant cell astrocytomas;
• Renal angiomyolipomas;
• Renal cysts;
• Renal cell carcinoma (associated with tuberous sclerosis);
• Retroperitoneal lymphangiomyomatosis;
• Gastrointestinal polyps;
• Pancreatic neuroendocrine tumors;
• Lymphangioleiomyomatosis;
• Multifocal micronodular pneumocyte hyperplasia;
• Cardiac rhabdomyomas.

CT Examples of Tuberous Sclerosis

This CT image shows randomly arranged cysts in both lungs. The patient had TSC and a renal AML.

This is an image from a contrast-enhanced computed tomography (CT) scan of the abdomen in another patient with TSC.
