[Show abstract][Hide abstract] ABSTRACT: We report on a 9-year-old boy who developed subependymal giant-cell astrocytoma associated with tuberous sclerosis. Apart from a few hypopigmented skin patches, the boy's clinical picture was completely unremarkable until the onset of diplopia and vertigo reflecting increased intracranial pressure. Magnetic resonance imaging of the brain revealed subcortical hamartomas in addition to the intraventricular tumour. Seizures and mental retardation were absent. The boy's mother had suffered from seizures during childhood and presented with typical skin lesions. The importance of thorough examination and regular follow-up even in patients with oligosymptomatic variants of tuberous sclerosis is emphasized.
[Show abstract][Hide abstract] ABSTRACT: We report on a 9-year-old boy who developed subependymal giant-cell astrocytoma associated with tuberous sclerosis. Remarkably, the boy was not mentally retarded and never had suffered from seizures. Apart from white skin patches symptoms of increased intracranial pressure were the presenting symptoms. The boy's mother, who was present at the boy's admission, presented with skin lesions typical of tuberous sclerosis. The importance of thorough examination of apparently asymptomatic relatives of patients with tuberous sclerosis is emphasized.

[Show abstract][Hide abstract] ABSTRACT: MR examinations of bone marrow variations in the spine after radiotherapy were performed on 24 patients in the thoracic and lumbar vertebral column. The actinically affected bone marrow showed a characteristic increase of signal intensity in T1-weighted sequences in the sagittal plane, due to conversion of red marrow to fatty marrow. The dose in the well-defined radiation areas was between 28 and 70 Gray (Gy). The lowest dose, applied to the bone-marrow bordering on the defined radiation areas, where we still could find an increase of signal intensity, was below 2.6 to 5 Gy. MR imaging was performed between 6 and 9 month after radiotherapy.
