MR imaging of heat stroke: external capsule and thalamic T1 shortening and cerebellar injury.
نویسندگان
چکیده
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.

Heat stroke: increased signal intensity in the bilateral cerebellar dentate nuclei and splenium on diffusion-weighted MR imaging.
Cerebellar Dentate Nuclei and Splenium on DiffusionWeighted MR Imaging Heat stroke is a critical illness characterized by hyperthermia (elevated core body temperature 40°C) with accompanying life-threatening complications. Previous MR imaging findings of heat stroke included diffuse atrophy of the cerebellum; hyperintense lesions in the cerebellum, external capsule and adjacent lateral putamen,...
متن کاملMR imaging assessment of myelination in the very preterm brain.
BACKGROUND AND PURPOSE MR imaging was performed in very preterm infants by using an MR imager in the neonatal intensive care unit. The aims of this study were to assess the development of myelination in the preterm brain based on MR imaging findings and to compare the ability of T1-weighted conventional spin-echo, inversion recovery fast spin-echo, and T2-weighted fast spin-echo MR imaging to s...

BACKGROUND AND PURPOSE DTI can provide information about brain ultrastructure by quantifying water diffusion. Our objective was to assess the value of DTI in detecting the acute effects of alcohol on healthy human brains. MATERIALS AND METHODS Sixteen healthy volunteers were studied with conventional MR imaging and DTI before and 0.5, 1, 2, and 3 hours after the initiation of acute alcohol ad...
متن کاملProfound asphyxia in the premature infant: imaging findings.
PURPOSE To investigate imaging findings in premature infants who had profound asphyxia. METHODS CT (three patients), MR (three patients), and ultrasonography (four patients) studies of five patients who had profound asphyxia before the postconceptional age of 32 weeks were retrospectively reviewed. The patients ranged from 1 day to 4 months old at the time of the imaging studies. An autopsy r...

PURPOSE To investigate the imaging and pathologic characteristics of acute encephalopathy with bilateral thalamotegmental involvement in infants and children. METHODS Five Japanese children ranging in age from 11 to 29 months were studied. We performed CT imaging in all patients, 10 MR examinations in four patients, and an autopsy in one patient. RESULTS The encephalopathy affected the thal...
