Tuberous sclerosis is a genetic disease with autosomal dominant inheritance, 
associated with hamartomas in several organs and various skin findings. A case 
of a ten year old boy is presented here to highlight the multisystem involvement 
in tuberous sclerosis. The child had seizures, facial papular naevi and 
peri-ungual fibromas. MRI revealed cortical tubers, white matter lesions and 
subependymal nodules. Orbital ultrasound showed retinal hamartoma on the left 
side. Ultrasound of the abdomen revealed a soft tissue mass at the upper pole of 
left kidney with a small cyst in right kidney.
