A 48-year-old man has felt discomfort and fullness of left eye for 4 months. He noticed left infraorbital mass 2 months ago and visited our clinic. The corrected visual acuity was 1.0 in both eyes. Exophthalmometry showed 12mm in the right eye and 14mm in the left eye (bar:100mm). A hard, non tender, immobile mass was palpable in the infraorbital area of the left eye. Computed axial tomography showed low density cystic mass with rim enhancement which extended from the anterior wall of the maxillary sinus to the infraocular area. At operation, the cystic mass had yellowish mucopurulent material and eroded the anterior wall of maxillary sinus and the orbital floor. The mass was not connected with the maxillary sinus. On the light microscopic examination, the cystic mass was lined with pseudostratified ciliated columnar epithelium and diagnosed as mucopyocele. Occasionally the sinus is congenitally divided by bony septa into two more or less separate cavities. In this case, the mucopyocele was thought to be originated from congenitally septated maxillary sinus presenting as infraorbital mass.
Key Words: infraorbital mass;mucopyocele;septated maxillary sinus
