Rocky Mountain Spotted Fever Masquerading as Gastroenteritis: A Common but Overlooked Clinical Presentation

David S Braun et al. Cureus. .

Abstract

Rocky Mountain spotted fever (RMSF) is a tick-borne illness caused by Rickettsia rickettsii. The classic triad of fever, rash, and a recent tick bite is rarely present at diagnosis. Less known, but more common initial presentations include gastrointestinal symptoms such as anorexia, nausea, vomiting, and abdominal pain. In endemic areas, a persistent fever with gastrointestinal symptoms should prompt screening and early initiation of antibiotics to prevent the development of fulminant RMSF and its associated high mortality. This case aims to educate about the gastrointestinal and hepatic manifestations of this diagnostic enigma.

Keywords: abnormal liver function test; enteritis; fever; gastroenteritis; rocky mountain spotted fever.
