Orbital mucopyoceles. Two cases and a review.

Two patients with superior orbital masses that were initially diagnosed as orbital cellulitis with abscess formation had orbital mucopyoceles, from which Enterobacteriaceae was cultured. Both patients had frontal sinus involvement and one had massive destruction with posterior extension abutting the frontal lobes. The radiology, computerized tomography, surgical procedures, and histopathologic findings pertaining to each case and the disease entity are reviewed. Antibiotic usage is discussed.
