Male, 8 years old, with neurologic deterioration. Assess for cerebellar degeneration or cerebral atrophy. Diagnosis of hereditary ataxia, unspecified. Patchy areas of white matter T2 hyperintensity seen on prior examinations have essentially resolved. Perivascular spaces are noted within the periatrial regions but this is within normal limits. The pattern of white matter myelination is mature. No areas of parenchymal edema or mass effect are seen. No intracranial hemorrhage or abnormal extra-axial fluid is seen. Ventricles are normal in size and morphology. The cerebral sulci are questionably and subjectively more prominent than on prior examinations. The cerebellar fissures more clearly seem to show progressive widening when compared to the prior exams.Patchy mucosal thickening and/or secretions are noted within the paranasal sinuses.
1.Mild interval progression in loss of cerebellar volume is seen.2.Questionable progressive prominence of the cerebral sulci could also indicate some very mild loss of cerebral volume, though this finding is equivocal.3.No acute intracranial abnormality.
