A case of extreme hemodynamic lability and hypocalcemia.

An epinephrine-secreting pheochromocytoma can present with a confusing picture of hemodynamic lability with rapid fluctuations between hypo- and hypertension. They are challenging to manage and diagnose. We herein present the case of a 44-year-old patient who presented with extreme hemodynamic lability due to an epinephrine-secreting tumor. We discuss the initial management, diagnosis, and definitive therapy of this relatively rare type of pheochromocytoma.
