Evolutive radiological findings in a case of coccidioidal infection in an immunocompetent male: a case report

Abstract

Abstract Background Bone infections such as chronic fungal erosive osteomyelitis are uncommon forms of bone infection. The endemic dimorphic fungus Coccidioides impact generally immunocompromised patients. These infections frequently have no symptoms and the clinical signs remain undetected, allowing the infection to worsen over weeks or months. Mycotic arthritis is one of the rarest clinical symptoms; it is hard to distinguish from other types of arthritis, which slows down the diagnosis procedure. Case presentation In order to demonstrate the beginning and progression of radiological abnormalities in a case of aggressive fungal osteomyelitis, we provide the case of a 31-year-old male patient here. The man showed signs of extensive bone erosion and inflammatory involvement in his right knee and right hallux phalanx, although he had no prior history of immunodeficiency. The infection resulting from Coccidioides Immitis in his right knee and in his hallux was the reason for the injuries. Conclusions While an acute, benign, and self-eradicating lung infection is the predominant presentation for most cases of coccidioidomycosis, a small percentage of patients experience a devastating extrapulmonary condition, which can include arthritis. The pathogenic mechanism of bone involvement is unknown, and it often remains untreated. Here, we discuss radiographic evidence of particular bone inflammation during the early phase and later phases of the disease, since management of this chronic condition remains a challenge. We propose that imaging may mimic osseous neoplasia in persistent fungal diseases, such as coccidioidomycosis.
