Radiological Comparison And Evaluation Of Faciomaxillary Tumour Or Tumor Like Lesions: A Case Series

Abstract

Background: Faciomaxillary tumors and tumor like lesions can occur at all age groups irrespective of the gender. The lesions also do not demonstrate a specific location as most of them can occur in both mandible and maxillary region with involvement of tooth. These lesions cannot be distinguished based on the radiological appearance as most of the lesions have overlapping features and hence the patient has to undergo invasive procedure to get a definitive diagnosis. (10) Materials and Methods: Study design: Retrospective observational case series in tertiary care center. Study area is Bagalkote district, in the northern part of the Indian state of Karnataka. Study population: All patients reporting to the department of Radiodiagnosis from Oral Medicine department with OPG suggesting a lytic lesion in SNMC and HSK, Bagalkot. Study Time: Study done for a period of 26months were taken into consideration from March 2021 to April 2024 Results: Over 70 percent of the lesions were found in the mandible while the rest 30 percent was in the maxillary region. Computed tomography showed that around 90% of the case were unilocular solid cystic lesions while the rest were multilocular lesions.Out of 20 cases 11 were found to have features of odontogenic keratocyst. Among these 11 cases, 5 were given a differential diagnosis of ameloblastoma out of which 3 were proven to be ameloblastoma on HPR;3 were given a differential of dentigerous cyst with 2 being histologically proven and 2 of the cases had overlapping features of periapical cysts.6 cases were given differential diagnosis of periapical cyst or dentigerous cyst. One case was found to be ameloblastoma histologically whereas rest were found to be dentigerous cysts. Conclusion: Faciomaxillary lesions cannot be distinguished based on the OPG and computed tomography appearance as most of the lesions have overlapping features and hence the patient has to undergo invasive procedure to get a definitive diagnosis
