Abstract:
Fever complicated by delirium is a common problem in emergency departments and inpatient wards. There are various possible causes that must all be contemplated. Infections are prominent causes due to acuteness and severity, but when generating a differential diagnosis, other causes may be life-threatening and require swift diagnosis and management. We present here a case of a 58 year old man presenting at the emergency department with fever and delirium. After comprehensive history-taking and examination, alongside targeted testing, the correct diagnosis was ascertained, leading to appropriate treatment.
