Endoscopic Endonasal Surgery for a Pterygopalatine Fossa Hydatid Cyst.

Background: Cystic echinococcosis is a manifestation of a zoonosis caused by larvae of the tapeworm Echinococcus granulosus sensu lato and pterygopalatine fossa cases are extremely rare. Clinical Presentation and Findings: A 45-year-old Caucasian female with a history of repeated surgeries for HC was referred to our center for treatment of a cystic mass of the pterygopalatine fossa. Multiorgan dissemination was noted on preoperative imaging. Interventions: An endonasal endoscopic procedure was carried over under general anesthesia and the CE completely removed. Etiology was confirmed by molecular diagnostics. Three weeks after the skull base procedure, the patient underwent a combined abdominal/urological procedure for treatment of other cysts.
Conclusion: This case shows that the pterygopalatine fossa HC are amenable to surgical treatment using the endonasal endoscopic approach. Extensive preoperative workup is essential to assess the extent of the disease. © The Association of Oral and Maxillofacial Surgeons of India 2021.
