Multimodal Imaging of Constrictive Pericarditis Induced by Long-term Pergolide Treatment for Parkinson's Disease.

We herein report the first case of constrictive pericarditis (CP) induced by long-term pergolide treatment for Parkinson's disease that was assessed using multimodal imaging in a 72-year-old patient with leg edema and dyspnea. The patient was correctly diagnosed with CP using multimodal imaging and successfully treated with pericardiectomy. The treatment history of Parkinson's disease and pathological findings of the removed pericardium suggested that long-term pergolide was the cause of CP. Properly recognizing pergolide as the cause of CP and accurately diagnosing CP using multimodal imaging may contribute to the early detection and treatment of pergolide-induced CP.
