Abstract
CBCT is considered by some to be the gold-standard diagnostic imaging in the field of oral radiology. However, this modality of imaging has important limitations. Of these limitations, interpreting ill-defined radiolucent areas proves to be a challenge. Case 1 presented with palatal gingival inflammation and a periodontal defect in the maxillary right lateral incisor area. CBCT depicted an ill-defined radiolucent area surrounding the crown and coronal half of the root of the impacted maxillary right canine with disruption of the cortices of the incisive foramen and surrounding bone. Case 2 presented with a semi-compressible soft tissue mass in the maxillary left posterior vestibule area of an extensively restored dentition. CBCT depicted an ill-defined radiolucent area at the apices of the maxillary left second molar with disruption of the cortex of the maxillary sinus. Rarefying osteitis was considered unlikely as no sclerotic reaction around the lesions was noted. Thus, the CBCT images were more consistent with malignant neoplasms. Histopathologically, Case 1 revealed a cystic wall of edematous stratified squamous epithelium and underlying connective tissue with scattered inflammatory infiltrates consistent with an inflamed dentigerous cyst. Case 2 revealed sheets of pleomorphic enlarged lymphocytes with frequent mitoses, tangible body macrophages and apoptosis. Immunohistochemical staining led to a diagnosis of non-Hodgkin’s lymphoma, diffuse large B-cell. As demonstrated, interpretation of ill-defined radiolucent images using only CBCT images continues to be a diagnostic challenge.
