Coccidioides immitis in the gallbladder and biliary tree.

Intraabdominal coccidioidomycosis is a very rare entity and usually responds to medical therapy. Operative intervention is reserved for diagnosis or drainage of localized collections. With biliary coccidioidomycosis, medical treatment appears to be ineffective, and biliary tract drainage is necessary for optimal management. A case of coccidioidomycosis in the gallbladder and biliary tree is described and the literature reviewed.
