Ameloblastoma is a benign but locally invasive odontogenic tumor. It is found most often in the posterior mandible and occurs as a slow growing painless mass. Diagnosis is made based on the clinical, radiographic and histopathologic features. Newer imaging modalities such as cone beam computed tomography offer massive advantage over traditional radiography thereby helping in better diagnosis an...

BACKGROUND To identify baseline radiographic features that predict hip osteoarthritis (HOA) progression, and to explore differences in these associations by race. METHODS Radiographs from the community-based Johnston County OA Project were scored using Kellgren-Lawrence (KL) grade and for presence and location of joint space narrowing (JSN), osteophytes, and subchondral changes. Associations ...

cent hemithorax is seen at frontal chest radiography are often encountered. Because such an abnormality is related to various conditions, including radiographic artifacts, chest wall abnormalities, pulmonary vascular disorders with reduced perfusion, and lung parenchymal abnormalities with air trapping or compensatory overexpansion, a radiographic finding of increased radiolucency involving one...

Hot tub lung (HTL) is a granulomatous lung disease thought to occur as a result of a hypersensitivity response to non-tuberculous mycobacteria (NTM). Typical radiographic findings are diffuse micronodular and/or ground glass opacities. We report an interesting case of HTL that presented with unique radiographic features, making its diagnosis a predicament. A 56-year-old immunocompetent female w...

osteosarcoma (os) is a malignant mesenchymal tumor, which rarely occurs in the maxilla. although variable histologic and radiographic features of os have been reported previously, in the majority of the cases painful swelling of the jaw is mentioned as the first clinical presentation. furthermore, early diagnosis and wide surgical resection of the tumor are the most important determinant factor...

We report two cases of epithelioid hemangioma (EH) manifested in the thoracic spine with associated clinical, radiographic, and pathological findings. Epithelioid hemangioma is a benign vascular tumor that can involve any bone (including the spine in a subset of patients). Although recognized as a benign tumor by the WHO, it can display locally aggressive features. Within the spine, these featu...
