ABSTRACT
OBJECTIVES:
The aims of this study are to describe the radiological appearance of two common odontogenic lesions (keratocystic odontogenic tumor and ameloblastoma) arising in the same patient simultaneously with their radiological differences and histological correlates, and to describe challenges in radiological diagnosis.DESIGN:
Single case report.SETTING:
Tertiary referral center.PARTICIPANTS:
Forty-one year-old African-American male patient. MAIN OUTCOMEMEASURE:
Lesion appearance on computed tomography (CT) scan and pathological correlates.RESULTS:
A 41year-old African-American male presented with asymptomatic right maxillary swelling. A CT scan of the maxillofacial skeleton showed and expansile and cystic lesion of the right hemimaxilla with trabecular osseous expansion, and a left cystic lesion in the left hemimaxilla expanding into the pterygopalatine fossa. Biopsy confirmed the suspected diagnoses of right ameloblastoma and left keratocystic odontogenic tumor.CONCLUSION:
Although they are among the most common odontogenic tumors, the presence of concurrent ameloblastoma and KOT is an exceedingly rare occurrence in the same patient. The appearance on CT scan may help in distinguishing ameloblastoma from KOT by looking at bone expansion and high density areas, although the gold standard diagnostic test remains open biopsy.
