Respiratory epithelial adenomatoid hamartoma (REAH) is a rare benign nonneoplastic sinonasal lesion that usually presents unilaterally. We report an unusual case of bilateral olfactory fossa REAHs mimicking an olfactory neuroblastoma that originated from the superior aspect of the middle turbinates. To our knowledge, only 1 similar case has been reported to date. Rhinologists and skull base surgeons should be aware of this rare entity to prevent unnecessary radical surgical interventions. Complete removal can be performed using a minimally invasive endonasal endoscopic approach.
