J. Neuroradiol.2010 Feb 01; 31 AB - SUMMARY: REAH is a rare benign lesion of the sinonasal tract. The nasal cavity, particularly the posterior nasal septum, is the most common site of involvement. It usually occurs unilaterally and can be cured with conservative surgical resection. We present an unusual case of adenomatoid hamartoma involving bilateral olfactory recesses and discuss the importance of distinguishing this from other neoplastic processes that may lead to overly aggressive treatment.
