Achromobacter xylosoxidans is an uncommon pathogen of low virulence known to cause serious nosocomial infection in the immunocompromised. Its inherent multi-drug resistance makes treatment difficult. Community-acquired infections are rare despite its ubiquitous existence. We present a 50-year-old immunocompetent woman who presented with one-month history of coughing with expectoration who was subsequently diagnosed with bilateral upper lobe pneumonia and acute adrenal insufficiency. Achromobacter xylosoxidans was isolated from sputum and bronchoalveolar lavage culture. The acute adrenal insufficiency recovered after appropriate antibiotic therapy. Amongst the myriad of presentations, we highlight the rarity of acute adrenal insufficiency triggered by the infection.
