Imaging studies revealed a large, diffuse radiopaque mass in the upper right posterior maxilla, with a differential diagnosis favoring fibrous dysplasia. The patient underwent surgical excision via hemimaxillectomy under general anesthesia. Histopathological examination revealed a cavernous hemangioma. No perceptible aesthetic sequelae or recurrence was observed at follow-up months after treatment.  \nClinical Discussion: In the maxillofacial area, it is a rare entity, with the intraosseous type being even rarer, accounting for less than 1% of all bony tumors. The mandible is the most commonly affected site, accounting for approximately two-third hemangiomas of the jaw. The clinical manifestations of maxillary cavernous hemangiomas are highly variable and often nonspecific, making diagnosis challenging.  \nConclusion: Cavernous hemangiomas should be included in the differential diagnosis of maxillary sinus lesions. Surgical excision is the treatment of choice and results in an excellent prognosis with low recurrence rates.  \nKeywords: cavernous hemangioma, facial deformity, intraosseous tumor, maxillary sinus, vascular malformation  \nIntroduction  \nCavernous hemangiomas are characterized by deep, irregular dermal tangles of large, slender-walled vessels or sinusoids lined with an incomplete layer of endothelial cells and separated by minimal connective tissue[1]. They are more common in the head and neck region, with the orbit and scalp being the most frequent sites; however, nasal cavity and paranasal sinus involvement is rare[2]. Hemangiomas are histopathologically classified into three main  \naBiomedical Science Department, Komar University of Science and Technology, Sulaymaniyah, Kurdistan Regional Government, Iraq, bDepartment of Oral and Maxillofacial Surgery, Baxshin Hospital, Sulaymaniyah, Kurdistan Regional Government, Iraq, cBaxshin Research Center, Baxshin Hospital, Sulaymaniyah, Kurdistan Regional Government, Iraq, dDirectorate General of Health Service, Ministry of Health and Family Welfare, Government of Bangladesh, Dhaka, Bangladesh, eSchool of Medical, Health and Applied Sciences, Central Queensland University, Rockhampton, Australia and fRockhampton Base Hospital, Central  \nQueensland Hospital and Health Service, Rockhampton, Australia Sponsorships or competing interests that may be relevant to content are disclosed at the end of this article.  \n*Corresponding author.
