MR imaging of heat stroke: external capsule and thalamic T1 shortening and cerebellar injury.
We present a case of increased signal intensity of the cerebrum (symmetric involvement of the paraventricular thalamus and external capsule) and cerebellum on both T1- and T2-weighted images in a patient with documented heat stroke. An ischemic and hemorrhagic mechanism is proposed, and the contributions of the direct effects of hyperthermia are discussed.
