Choreiform-ballistic movements have often been associated with lesions in basal ganglia and sub-thalamic nucleus. For a patient with dancing movements, hyperglycemia might be an initial presentation. We report a rare case of 19 years old Asian girl who had type I diabetes mellitus and Developed choreiform-ballistic type movements. She had ketoacidosis secondary to uncontrolled hyperglycemia along with hypocalcaemia secondary to either pseudo hypoparathyroidism??? On CT brain plain basal ganglia were heavily calcified. We optimized her diabetes management along with calcium and vitamin D analogues (calcitriol or alfacalcidol) and her symptoms got improved dramatically without using any specific antidopaminergic therapy or nerve stabilisers. Adults with mixed endocrine deficiencies can present with unique symptoms like choreiform-ballistic type movements that can be improved with exogenous administration/replacement of deficient harmones' analogues like in above mentioned case with insulin as well as calcium and vitamin D analogues supplementation.
