The case of 36-year-old man is reported who fell ill with a febrile in
fection, shortly after returning from several weeks to Mexico. Examina
tion: Chest X-ray revealed a pulmonary infiltration. Also, the levels
of liver function tests (gamma-GT, alkaline phosphatase, SGOT, SGPT) w
ere clearly increased. As there were no signs of extended bile ducts i
n ultrasonics, a liver biopsy was indicated. The histology showed a gr
anulomatous hepatitis. Diagnosis: The exposure during the Mexico-trip,
the pulmonary infiltration, the histology and the significant raised
titers in specific serological tests led to the diagnosis of a general
infection by the fungus coccidioides immitis. In addition to pathogen
etic aspects of coccidioidomycosis the diagnostic approaches and relev
ant therapeutic strategies are discussed.
