Levodopa-induced pseudopheochromocytoma
Pseudopheochromocytoma is a pathological condition presenting with paroxysmal hypertension with normal or moderate elevation in catecholamines and metanephrine levels, but no evidence of a tumoural cause. Imaging studies and I-123 metaiodobenzylguanidine scintigraphy are essential for exclusion of pheocromocytoma.
