Valley fever

San Joaquin Valley fever; Coccidioidomycosis, Cocci; Desert rheumatism

Valley fever is an infection that occurs when the spores of the fungus Coccidioides immitis enter your body through the lungs.

Coccidioidomycosis - chest X-ray

This chest x-ray shows the affects of a fungal infection, coccidioidomycosis. In the middle of the left lung (seen on the right side of the picture) there are multiple, thin-walled cavities (seen as light areas) with a diameter of 2 to 4 centimeters. To the side of these light areas are patchy light areas with irregular and poorly defined borders. Other diseases that may explain these x-ray findings include lung abscesses, chronic pulmonary tuberculosis, chronic pulmonary histoplasmosis, and others.

Pulmonary nodule - front view chest x-ray

This x-ray shows a single lesion (pulmonary nodule) in the upper right lung (seen as a light area on the left side of the picture). The nodule has distinct borders (well-defined) and is uniform in density. Tuberculosis (TB) and other diseases can cause this type of lesion.

Disseminated coccidioidomycosis

Disseminated coccidioidomycosis is caused by breathing in the spores of a fungus found in desert regions. The infection spreads throughout the body and is especially common in immunosuppressed people. Antifungals may help but the death rate is very high.
