Maxillary Tumor in the Base of the Skull

Abstract

A large bony swelling in the region of body of maxilla with extension to nasal, zygomatic and palatal region suspected to be a malignant tumor or aggressive benign tumor is clinically recorded and investigated. Conventional radiograph of skull reveals that a radiopacity in the region of body of maxilla obliterating the maxillary antrum with areas of radiolucency. The radiopacity extends to nasal, zygomatic, palatal and lateral wall of the nose. Computerized Tomography image revealed in both coronal and axial view, a well-defined soft tissue mass with areas of calcifications. The mass extended to the base of the skull towards the lateral part of the sphenoid sinus. The margins are well defined and not infiltrative in nature. Biopsy revealed that it was a cemento-ossifying fibroma. Thus a swelling clinically appeared as malignant tumor was diagnosed as benign tumor with extension to the base of the skull without any complications. The case is presented and discussed.
