Most commonly, it involves the nasal sinuses or orbital bone. It is very important to differentiate it from other fibro-osseous lesions because these lesions have overlapping clinical features. Even though it is a benign condition, it is locally aggressive and rarely extends intracranially. A complete surgical resection is the key to avoid recurrence. We are presenting a case of JPOF in a 16-year-old boy with a large tumor involving the ethmoidal sinuses with large intracranial component.<\/jats:p>","DOI":"10.1055\/a-2779-6238","type":"journal-article","created":{"date-parts":[[2025,12,30]],"date-time":"2025-12-30T23:58:06Z","timestamp":1767139086000},"page":"e6-e12","source":"Crossref","is-referenced-by-count":0,"title":["A Rare Case of Intracranial Extension of Ethmoidal Sinus Juvenile Psammomatoid Ossifying Fibroma"],"prefix":"10.1055","volume":"87","author":[{"given":"Sagar","family":"Gawali","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, L.
