title: Barium stone impaction in parkinsonism.
abstract: Autonomic symptoms such as orthostatic hypotension, abnormal sweating and constipation occur frequently in Parkinson's disease. In our case, barium meal used for upper gastrointestinal study caused barium stone formation and a paralytic-ileus-like syndrome. Therefore, attention should be paid while using barium meal for diagnostic purpose in Parkinsonism.
