Advanced Imaging Techniques in Skull Base Osteomyelitis Due to Malignant Otitis Externa

Curr Radiol Rep. 2018;6(1):3. doi: 10.1007/s40134-018-0263-y. Epub 2018 Jan 22.


Purpose of review: To give an up-to-date overview of the strengths and weaknesses of current imaging modalities in diagnosis and follow-up of skull base osteomyelitis (SBO).

Recent findings: CT and MRI are both used for anatomical imaging, and nuclear techniques aid in functional process imaging. Hybrid techniques PET-CT and PET-MRI are the newest modalities which combine imaging strengths.

Summary: No single modality is able to address the scope of SBO. A combination of functional and anatomical imaging is needed, in the case of newly suspected SBO we suggest the use of PET-MRI (T1, T2, T1-FS-GADO, DWI) and separate HRCT for diagnosis and follow-up.

Keywords: CT; MRI; Malignant otitis externa; PET-CT; PET-MRI; Skull base osteomyelitis.
