Giant cell astrocytoma in tuberous sclerosis: computed tomographic findings.
Clinical presentation and computed tomography (CT) findings in four tuberous sclerosis patients with large ventricular tumours situated near the foramina of Monro, and causing obstructive hydrocephalus are described. These tumours (so-called giant cell astrocytomas) demonstrated uniform post-contrast enhancement. This finding, along with their location, distinguished them from the much commoner cortical and subependymal tubers of tuberous sclerosis.
