“…Hemangioma, angiofibroma, antrochoanal polyp, nasoethmoidal encephalocele, nasal glioma, inverted papilloma, giant cell reparative granuloma, ossifying fibroma, chondro-osseous respiratory adenomatoid hamartoma, and aneurismal bone cysts along with other rare benign pediatric tumors constitute the broad list of differential diagnose. [8,[20][21][22] Exclusion of nasoethmoidal encephalocele and nasal glioma in differential diagnosis is considerably important so as to avoid neurologic complications of surgical therapy. On imaging sections of nasoethmoidal encephalocele, a bone defect is almost always seen with no destruction of the anterior cranial fossa, cystic lesions show a thin peripheral halo with soft central tissue.…”
