Fast micrographia: An unusual but distinctive sign

Abstract

Fast micrographia is a rare clinical sign, which is reported in patients with pallidal pathology. A 68-year-old male presented with hypophonia and short shuffling gait with decreased arm swing. About 3 weeks before, he had an acute myocardial infarction and a period of hemodynamic and respiratory distress during which he required mechanical ventilatory support. He was found to have a fast handwriting with micrographia from the outset. His rapid alternating hand and finger movements were normal. Magnetic resonance imaging (MRI) of the brain showed features of hypoxic ischemic encephalopathy including hyperintensities on T1 and T2 weighted images in the globus pallidus, and putamen bilaterally.
