[Simultaneous Diagnosis of Emphysematous Osteomyelitis and Superimposed Bony Metastasis in a Patient with Colon Cancer: A Case Report]

Emphysematous osteomyelitis is a particularly rare disease diagnosed by the presence of intraosseous gas and positive bone culture results. Radiologically, this disease is characterized by irregular intraosseous air density patterns. In particular, emphysematous osteomyelitis caused by Clostridium septicum has been reported in only two cases worldwide, one of which occurred in a patient with colon cancer. However, concurrently occurring emphysematous osteomyelitis with bone metastasis has not been described yet. Here, we report a case of emphysematous osteomyelitis accompanied by bone metastasis, focusing on the radiologic findings.
