ABS TRACT Non-ketotic hyperglycaemic hemichorea is a rare syndrome characterized by a triad of hemichorea, hyperglycemia, and peculiar imaging abnormalities. Regression of symptoms is typically associated with normalisation of serum glucose levels and plasma osmolality. An 85 year-old female was admitted to the neurology clinic with left-sided involuntary movements. Magnetic resonance imaging of brain demonstrated hyperintensity on T1 weighted images. She was treated with clonazepam (12. 5 mg/ day) for symptomatic therapy. Hyperglycaemia was controlled using a combined therapy with insulin aspart and insülin glargine. The patient showed prompt improvement in her involuntary movements in a day. Acute or subacute onset of unilateral involuntary movements should suggest non-ketotic hyperglycaemic hemichorea, the recognition of which may result in prompt control of the symptoms by normalization of blood glucose.

Radiation myelopathy (RM) is a rare but serious complication of radiotherapy. Small vessel ischemia and demyelination are some of the more remarkable indications of RM's pathophysiology. The RM is a diagnosis of exclusion. In the differential diagnosis, infectious causes, tumors, rheumatic diseases, and paraneoplastic syndromes are the main diseases that should be excluded. Contrast-enhanced magnetic resonance imaging (MRI) is a useful method for diagnosis. We present a report on 3 patients diagnosed with radiation myelitis. All the patients presented with late paraparasia and paresthesia. Despite high-dose steroids, hyperbaric oxygen, and physical therapy, there was no clinical improvement at the follow-up one year later.
