Adrenal insufficiency secondary to adrenal hemorrhage. Two case reports and a review of cases confirmed by computed tomography

We report two cases of adrenal hemorrhage and review 17 others that were confirmed by hormone measurements and computed tomography. Precipitating factors included heparin therapy, surgery, hypotension, and sepsis. Heparin-associated thrombocytopenia may be an underappreciated cause of adrenal hemorrhage. Despite the availability of computed tomography, adrenal hemorrhage mimics many other diseases, and an early diagnosis remains difficult.
