Roentgenographic abnormalities in Rocky Mountain Spotted Fever.

Rock Mountain spotted fever (RMSF) is a tick-borne rickettsial disease which produces a widespread vasculitis. A mortality of 7% to 13% has been reported in the United States which is due at least in part to delay in diagnosis and appropriate treatment. The classic features of this disease include a history of tick bite with the clinical presentation of skin rash and fever in association with thrombocytopenia. Few reports have emphasized the radiologic chest abnormalities in this disease or their relationship to thrombocytopenia. We review 70 cases of RMSF with abnormal roentgenographic features and their pathologic correlation.
