[Difficulty in diagnosis of a cardiogenic shock with thrombotic and sub-occluded LAD. A train can hide another one!].

The pheochromocytome is a localized tumor at the level of the medullosurrenale in 85% of the cases. The clinical presentation is very variable. Severe Heart failure presentation can be the mode of revelation in 2% of the cases. We present the case of a patient admitted for refractory cardiogenic shock correlated to pheochromocytome tumor. The difficulty of this rare clinical presentation was to confirm rapidly and in emergency this diagnosis in the same time when the patient presents a persistante and severe cardiogenic chock after finding a sub-occluded and thrombotic LAD coronary artery and which was treated by thrombectomy and coronary revascularization. The surgical treatment of this tumor is considered to be a quickly saving treatment. It allows a fast recovery of the cardiac function.
