An Inflammatory Pseudotumor Arising from Pterygopalatine Fossa with Invasion to the Maxillary Sinus and Orbital Cavity

An Inflammatory Pseudotumor Arising from Pterygopalatine Fossa with Invasion to the Maxillary Sinus and Orbital Cavity

We report a patient who had an inflammatory pseudotumor (IPT) that invaded to the maxillary sinus and orbital cavity, with the left pterygopalatine fossa as the principal site; this is a very rare case. The patient was an 83-year-old woman who suddenly became aware of impairment in the eyesight and...
