Transient parkinsonism in bilateral striopallidodentate calcinosis.

A normally developed 12-year-old female drank a cup of tea and could not sleep that night. The next morning, symptoms suggestive of parkinsonism developed, including progressive rigidity, akinesia, and a mask-like face. These signs lasted for 10 days. Brain computed tomography revealed multiple calcification, and thus she was diagnosed as having bilateral striopallidodentate calcinosis. Patients with bilateral striopallidodentate calcinosis exhibit various movement disorders. However, there have been no reports of transient parkinsonism associated with bilateral striopallidodentate calcinosis, including in children.
