Anterior hypopituitarism due to primary empty sella syndrome in a critically unwell patient.

A previously fit and well male in his early 40s, presented to the emergency department, hypotensive, bradycardic and hypothermic with reduced levels of consciousness after being found diaphoretic and unwell at his home. Despite fluid resuscitation with warmed saline, he remained hypotensive and required vasopressor support leading to intensive care admission. Initially, the patient was managed for suspected meningoencephalitis but was later found to have hypopituitarism leading to secondary hypothyroidism and adrenal insufficiency.
