Ameloblastoma is a benign odontogenic tumor characterized by slow growth causing painless facial swelling. The tumor can behave locally aggressively, and may have direct destructive effects on the surrounding soft and hard tissues. This paper reports the unique case of a female patient with giant ameloblastoma of the mandible. Computed tomography (CT) revealed an enormous swelling of the left side of the face, resorption of the affected hemi-mandible, left maxilla, and tissues of the temporal, infratemporal, and pterygopalatine fossae. Pressure from the tumor resulted in displacement and destruction of the facial skeleton, upper aero-digestive tract structures, and some structures of the neck. The patient was treated by radical hemimandibulectomy with removal of the tumorous mass. Precise knowledge of the anatomical structures, and their locations and topographical relationships is required in the diagnosis and treatment plan for each surgical procedure in cases of giant ameloblastoma. CT imaging can be used to determine the extent and exact location of the lesion, revealing other important details that may help in selecting appropriate treatment.
