Figure 1
Axial T2‑weighted MRI shows a hyperintense signal in both cerebellar hemispheres and the brainstem, indicative of edema.
Figure 2
Axial ADC map demonstrates diffusion restriction predominantly in the cerebellar hemispheres and involvement of the brainstem, consistent with cytotoxic edema.
Figure 3
Sagittal T2‑weighted MRI showing an intense signal in the cerebellum, causing mass effect with anterior displacement of the medullar bulb.
Figure 4
Sagittal FLAIR‑weighted MRI image showing cerebellar atrophy following opioid‑induced toxicity. A pre‑existing cystic malformation of the posterior fossa, consistent with a Blake’s pouch cyst, remains visible.
