RESUMO
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 (AU)
El pseudotumor inflamatorio de cabeza y cuello es una entidad de naturaleza benigna y extremadamente infrecuente fuera de la localización orbitaria. Presentamos un caso de un pseudotumor inflamatorio no asociado a enfermedad relacionada con IgG4, localizado como una masa solitaria en la fosa infratemporal de una mujer joven que consultó por otalgia e hipoacusia. La imagen era evidente en una exploración PET con 18F-FDG. Una vez diagnosticado anatomopatológicamente y finalizado el tratamiento con corticoides, se realizó otra exploración PET con 18F-FDG en la que se normalizó la imagen metabólica y desapareció la masa. Se revisa la literatura sobre este tipo de lesiones (AU)
