Bilateral Adrenal Hemorrhage on CT: Imaging Diagnosis, Adrenal Insufficiency, and Emergency Management
1. Clinical Hook A 39-year-old woman presented with acute generalized abdominal pain and vomiting. Her previous history included abdominal hernia surgery and a prior episode of intestinal obstruction, making an intra-abdominal surgical or gastrointestinal process an understandable initial consideration. The CT examination, however, revealed something considerably more consequential: both adrenal glands were enlarged and heterogeneous, with abnormal changes in the surrounding fat . That observation changes the clinical question. The important question is no longer simply: What is causing this patient's abdominal pain? It becomes: Could bilateral adrenal injury be causing or contributing to acute adrenal insufficiency? This distinction matters because unilateral adrenal hemorrhage is often clinically silent or self-limited, whereas extensive bilateral adrenal injury can destroy sufficient cortical tissue to produce primary adrenal insufficiency and, in severe cases, adrenal crisis.
