Acute Cytotoxic Cerebellar Edema Subsequent to Fentanyl Patch Intoxication in an Infant

Figure 3

MRI at the time of presentation. (a) Axial T2-weighted image shows bilateral cerebellar edema (arrows) with effacement of the inferior fourth ventricle (dashed arrow). (b) Midsagittal T2 weighted image shows posterior fossa crowding with effacement of the inferior fourth ventricle (dashed arrow). (c) Diffusion imaging and (d) apparent diffusion coefficient (ADC) map show true restricted diffusion in the cerebellar hemispheres (arrows) in the region of T2 signal abnormality consistent with cytotoxic cerebellar injury.
