Coccidioides immitis Cervical Lymphadenitis Complicated by Esophageal Fistula

الملخص EN

Coccidioidomycosis (valley fever) is caused by the dimorphic fungi Coccidioides immitis or Coccidioides posadasii.

Most infections are asymptomatic or result in self-limited pneumonia; extrapulmonary dissemination via either hematogenous or lymphatic spread is rare.

Here, we present a case of cervical C.

immitis lymphadenitis that resulted in fistula formation to the esophagus via mediastinal extension.

This case highlights a very unusual extrapulmonary manifestation of coccidioidomycosis, the difficulty in diagnosing coccidioidal infection when it is not suspected, and the importance of obtaining a thorough exposure history to assist with diagnosis.
