title: [Inflammatory pseudotumor of the paranasal sinuses].
abstract: The inflammatory pseudotumor of the head and of the neck is a lesion of unknown etiology which affects the orbita more frequently but cases have also been described in the paranasal sinuses, larynx, mouth, cervical column and by direct extension from the orbita in the Central Nervous System. In the majority of cases, it behaves as a limited benignant inflammation within the osseous walls of the area where it is to be found; other times it destroys the osseous limits and invades the surrounding areas, behaving as a neoplasia. It must be distinguished from sinusitis, granulomatous inflammations, vasculitis, diseases of the collagen, sarcoidosis, neoplasias and benignant tumours. We present a case of inflammatory pseudotumour, occupying the right maxillary sinus, nasal fossa and rhinopharynx. Surgical extirpation has been the treatment used.
