The inflammatory pseudotumour of the head and neck is a benign lesion, extremely rare outside the cranial orbits. A case is presented of an inflammatory pseudotumour not associated with the IgG4-related disease. The pseudotumour was found as a solitary mass in the infratemporal fossa of a young woman who complained of otalgia and hearing loss. A clear image of the lesion was obtained using an 18F-fluoro-deoxy-glucose (18F-FDG) PET. After the histopathological diagnosis, and treatment with corticosteroids, a second 18F-FDG PET was performed. The metabolic image had returned to normal, and the previously observed mass disappeared. A brief review is presented of the studies examining this type of lesion.

When performing a radiologic examination, it is important for the clinician to follow a diagnostic sequence. Specific viewing principles are necessary to create the proper physical environment to obtain the most information from the radiographs. The selection of radiologic examination must be based on the ALARA (As Low As Reasonably Achievable) principle, and the clinician should use a method approach to radiologic interpretation.
