Pheochromocytoma and paraganglioma are being reported in association with cardiomyopathy, a condition affecting the heart. These tumors can cause catecholamine-induced crises, leading to various complications, including multiorgan failure, arterial thrombosis, and hypertensive crises. The condition may present with atypical manifestations and diagnostic challenges, but treatment, such as tumor resection, can lead to improvement in cardiomyopathy.
