Abstract

Anaplasmosis is a now common tick-borne illness that is characterized by the presence of fever, myalgias, thrombocytopenia, and elevated liver function tests. We report 4 cases with an atypical presentation with pulmonary symptoms and imaging findings, along with the characteristics of each patient, clinical course, and response to therapy.

Keywords: anaplasma phagocytophila; anaplasmosis; pneumonia; pneumonitis; tick-borne illness.
