Hyperdense cerebral lesion in childhood tuberous sclerosis: computed tomographic demonstration and neuropathologic analysis.
A child with focal intractable seizures and electroencephalographic evidence of a highly epileptogenic focus was found to have a high-density, wedge-shaped lesion in the left parietal region on cerebral computed tomography. The lesion extended from the ventricular to the pial surfaces and did not enhance after contrast infusion. Biopsy confirmed the diagnosis of tuberous sclerosis. Atypical features of tuberous sclerosis on computed tomography are reviewed and the possible pathogenesis of the lesion is discussed.
