Abstract

Respiratory epithelial adenomatoid hamartoma (REAH) in the head and neck is a rare benign lesion containing glandular tissue covered with ciliated respiratory epithelium. In the head and neck, REAH of the nasal cavity, paranasal sinuses, and nasopharynx have been reported in literature. Due to rareness of REAH and insufficient knowledge of its imaging features, the diagnosis can be challenging when we encounter a non-specific cystic mass at an uncommon site in the head or neck. Here, we report the case of a pathologically confirmed REAH showing a cystic mass centered at the buccal space (retromaxillary fat pad) with CT and MRI findings.

두경부의 호흡상피 선종양 과오종은 섬모호흡상피로 둘러싸인 선조직으로 구성된 드문 양성종양이다. 두경부의 비강, 부비동 또는 비인강의 호흡상피 선종양 과오종이 현재까지 보고되었다. 호흡상피 선종양 과오종은 드물고 특징적인 영상 소견이 잘 알려져 있지 않기 때문에 흔하지 않은 위치에 비특이적인 낭성종물로 발생한 경우 영상의학적 진단을 내리기가 쉽지 않다. 저자들은 볼쪽공간(상악후방 지방층)에서 낭성종물의 형태로 나타난 병리적으로 진단된 호흡상피 선종양 과오종의 CT 및 MRI 영상 소견을 증례 보고하고자 한다.
