Curious case of reversible left ventricular dysfunction in a young woman.

A 27-year-old woman presented with breathlessness on exertion of 3 months duration and was treated as dilated cardiomyopathy elsewhere. On evaluation, she was found to have left ventricular hypertrophy with ventricular dysfunction. CT angiogram revealed a peripheral-enhancing mass with central necrosis in the aortocaval region. Elevated serum metanephrine and uptake in 131iodine metaiodobenzylguanidine scan lead to the diagnosis of paraganglioma. Patient underwent open surgical excision of the tumour. Left ventricular function became normal and left ventricular hypertrophy resolved after surgery.
