Operative Technique: Angiomatoid Fibrous Histiocytoma-Unique Case and Management.

Abstract

Objective  We describe the first jugular foramen angiomatoid fibrous histiocytoma (AFH) case and the first treatment with preoperative endovascular embolization. AFH is a rare intracranial neoplasm, primarily found in pediatric patient extremities. With an increase in AFH awareness and a well-described genetic profile, intracranial prevalence has also subsequently increased. Study Design  We compare this case to previously reported cases using PubMed/Medline literature search, which was performed using the algorithm ["intracranial" AND "angiomatoid fibrous histiocytoma"] through December 2020 (23 manuscripts with 46 unique cases). Patient  An 8-year-old female presented with failure to thrive and right-sided hearing loss. Work-up revealed an absence of right-sided serviceable hearing and a large jugular foramen mass. Angiogram revealed primary arterial supply from the posterior branch of the ascending pharyngeal artery, which was preoperatively embolized. Intervention  Gross total resection was performed via a translabyrinthine approach. Conclusion  The case presented is unique; the first reported AFH at the jugular foramen and the first reported case utilizing preoperative embolization. Preoperative embolization is a relatively safe technique that can improve the surgeon's ability to perform a maximally safe resection, which may decrease the need for adjuvant radiation in rare skull base tumors in young patients.
