How do you diagnose skull base osteomyelitis?

Several image-based techniques should be used to diagnose SBO. CT is the best option for evaluating bone erosion and demineralization, MRI can help delineate the anatomic location and extent of disease, and nuclear imaging is useful for confirming bone infection with high sensitivity.

Rarely, skull base osteomyelitis may be caused by paranasal infections. Infectious organisms are usually Aspergillus, Pseudomonas, Salmonella, and Staphylococcus species.
