Osteomyelitis of the Clivus Secondary to Mucormycosis

Osteomyelitis of the clivus secondary to mucormycosis is a rare infection of the clivus bone due to infiltration by fungi of the genus Mucor. Immunocompromised patients and/or those with diabetes mellitus are most at risk of developing this disease. Here, we present the case of a 63-year-old male patient with findings of gas within the clivus on computed tomography angiography. Diagnosis of mucormycosis osteomyelitis was confirmed after endoscopic biopsy and histopathologic examination. Furthermore, as this condition is very difficult to detect on imaging, we emphasize the discussion of typical radiology findings associated with this disease based on this and other case reports in the literature.
