Pheochromocytoma and Hypertrophic Cardiomyopathy Leading to Cardiac Arrest.

A 33-year-old female with no known past medical history presented to the hospital for a witnessed cardiac arrest. The patient was emergently intubated and sedated. Further investigation demonstrated an 8.5 cm x 7.6 cm mass in the adrenal region, which was subsequently found to be a pheochromocytoma by biopsy. She was transferred to a tertiary care center for further evaluation. We wish to raise awareness of this condition among clinicians and encourage further research into the connections between pheochromocytoma and further cardiac complications.
