Aneurysmal Bone Cyst (ABC) are extremely rare in the head and neck region and even rare in sinuses. It’s a benign multicystic mass that is locally-destructive and rapidly expandable. The etiopathogenesis, even today, is not entirely clear. However, hemorragic fluid content and septated appearance are the characteristic feature of ABC. The clinical presentation produces symptoms due to the compression of adjacent structures or as a result of a pathological fracture and depends on localization. Most common location in this area are the mandible and maxillary bones. The complete surgical excision is the treatment of choice. There are limited reports in literature on these tumors at the sinonasal level. We present a complete review of the literature as well as an unusual localization of ABC in this district.
