Description

Legionnaires’ disease or Legionellosis is a subtype of pneumonia caused by the gram negative bacilli, Legionella pneumophila.

L. pneumophila serogroup 1 accounts for 50-80% of Legionnaires’ disease.

Patients commonly present with fevers, chills, myalgia, cough and less commonly with confusion, nausea, vomiting, diarrhea, and/or anorexia.

Treatment primarily consists of antibiotics with supportive measures.

Renal and hepatic extrapulmonary manifestations from Legionella are rare, and often present with multisystem involvement when they do occur.

This case highlights a unique, and rare, presentation of Legionnaires’ disease mimicking alcoholic hepatitis with 2:1 AST/ALT transaminitis and physical exam findings.
