Abstract:
:We present the CT and MRI findings of a patient with Chédiak-Higashi syndrome in the accelerated phase with marked white-matter abnormalities. Pathologic and clinical features allow diagnosis of this condition, which in this case had dramatic neuroradiographic manifestations not well described in previous reports.
