Abstract

We present CT findings in a unique case of horseshoe maxillary sinus harboring a cholesteatoma. CT showed interconnected maxillary sinuses with an isthmus anteriorly at the level of hard palate forming a horseshoe-shaped sinus. An expansile soft tissue density mass was seen occupying both maxillary sinuses and the bridging cavity between them. To our knowledge, this is the first report of a horseshoe maxillary sinus.
