Diffusion-weighted MRI of van der knaap leukoencephalopathy. A case report

An eight-month-old girl was admitted with signs and symptoms of deterioration of motor functions. Cranial MRI demonstrated widespread bilateral increased signal of cerebral white matter on T2-weighted images accompanying bilateral cyst-like structures at the subcortical location of frontal and parietal lobes and bilateral cysts at the temporal lobes. On diffusion MRI, increased diffusion with high ADC values were detected. The patient was diagnosed as an MLC subtype of Van Der Knaap Leukoencephalopathy with clinical and radiological findings. Cranial MRI and diffusion MRI findings are discussed in this paper.
