RT Journal Article SR Electronic T1 A young man with a dizzy spell and acute abdominal pain JF Clinical Medicine JO Clin Med FD Royal College of Physicians SP 520 OP 521 DO 10.7861/clinmedicine.13-5-520 VO 13 IS 5 A1 Hassan Mohamed Saeed Elasha A1 Farees Anjum A1 Mussa H Almalki YR 2013 UL http://www.rcpjournals.org/content/13/5/520.abstract AB Isolated adrenocorticotropic hormone (ACTH) deficiency is a rare cause of secondary adrenal insufficiency and its presentation with adrenal crisis is rather rare. Acute adrenal insufficiency (adrenal crisis) can be an elusive diagnosis, particularly in previously undiagnosed patients. As in this patient, the presentation of adrenal crisis with acute abdominal pain was misdiagnosed as an acute surgical abdomen, leading to a delay in the diagnosis and in the initiation of life saving treatment.
