Case ReportsNon-ketotic hyperglycemia in a young woman, presenting as hemiballism-hemichorea.
We report a 22-year-old girl presenting with acute onset left sided hemiballism-hemichorea (HH) and non-ketotic hyperglycemia (NKH). Initial brain CT revealed faint hyperdensities, sharply confined to the contralateral nucleus caudatus and putamen. ⋯ The abnormalities seen in neuroimaging are rare, but seem to be quite specific to this syndrome. We give an update on current literature regarding the possible pathophysiological processes underlying this specific clinical entity.

Gd-DTPA enhancement of cranial nerves on MR imaging. Neoplastic lesions.
This study describes a radiological finding - enhancement of cranial nerves and correlates patients' clinical findings and outcome. Seven patients with enhancement of cranial nerves on postcontrast MR were retrospectively reviewed. Cranial nerves having contrast enhancement were optic, oculomotor, trigeminal, facial, acoustic, glossopharyngeal, vagus and accessory nerves. ⋯ In 2 cases, initial symptoms were sudden hearing loss. Autopsy was done for 1 case of metastatic tumor involving cranial nerves. Contrast MR is a useful examination for depicting cranial nerve involvement with neoplastic change.
