Reversible reduction of apparent diffusion coefficient values in bilateral internal capsules in transient hypoglycemia-induced hemiparesis.

چکیده
A woman aged 68 years who experienced recurrent right hemiparesis caused by hypoglycemia was admitted to our hospital. When she was experiencing a low level of glucose, diffusion-weighted MR imaging showed the presence of hyperintensity lesions in the bilateral internal capsule. Diffusion-weighted MR imaging has been infrequently performed in patients with hypoglycemia. We report the reversible hyperintensity lesions on diffusion-weighted MR imaging in a hypoglycemic period in a patient with reversible hemiparesis. A reduction of apparent diffusion coefficient in a hypoglycemic period was clearly shown.

Localized reversible reduction of apparent diffusion coefficient in transient hypoglycemia-induced hemiparesis.
BACKGROUND AND PURPOSE The pathophysiology of hypoglycemia shares a common mechanism with cerebral ischemia, but so far, little is known regarding MRI of humans with hypoglycemia. METHODS We report a patient with left hemiparesis and dysarthria associated with a blood glucose level of 1.7 mmol/L. The patient recovered completely after glucose infusion. RESULTS The initial diffusion-weighted...
متن کاملSevere Hypoglycemia-induced Right Hemiparesis with Reversible Diffusion Restriction in the Left Internal Capsule Due to Combination Therapy Using Disopyramide and Clarithromycin
Severe hypoglycemia is known to cause acute focal neurological symptoms. In cases with a medical history of diabetes mellitus (DM), the diagnosis and treatment of hypoglycemia-induced neurological symptoms are simple. However, severe hypoglycemia can occur in patients who are not taking hypoglycemic agents such as insulin or long-acting sulfonylurea drugs. We describe a 95-year-old man with sud...

A 41-year-old man with a 7-year history of insulindependent type I diabetes mellitus complained of right hemiparesis and was referred to our stroke center. Neurological examination revealed that his consciousness was alert, and he had dysarthria and right hemiparesis. Laboratory test values were within normal limits except for plasma glucose level (46 mg/dL). The dysarthria and right hemiparesi...

Case Report A 78-year-old woman with no history of stroke was taken to the Guro Hospital emergency department after being found dysarthric and less responsive at home. Her husband noted that on the day of admission she developed diaphoresis and tremulousness after not having two consecutive meals, followed by dysarthria, right-sided weakness, and somnolence. She was diagnosed as having type 2 d...
متن کاملDiffusion anisotropy of the internal capsule and the corona radiata in association with stroke and tumors as measured by diffusion-weighted MR imaging.
BACKGROUND AND PURPOSE Diffusion-weighted MR images have enabled measurement of directionality of diffusion (anisotropy) in white matter. To investigate differences in the anisotropy for various types of pathologic findings and the association between the anisotropy of tracts and neurologic dysfunction, we compared the anisotropy of the posterior limb of the internal capsule and the corona radi...
