Radiography is a good screening tool for malignant transformation of enchondroma. Radio- logic evidence of malignant transformation includes cortical destruction, endosteal cortical erosion and zones of lucency. Biopsy should be performed on suspicious radiologic areas....
Histologically, odontogenic epithelium is present assmall islands, elongated strands, or terminal buds of peripheral ameloblast-like cellsand central stellate reticulum cells. The odontogenic mesenchyme resembles the dental papilla. Surrounding the epithelial component there is frequently a cellular hyaline ma...
A small radiolucent lesion is challenging for radiologists to make an accurate diagnosis, especially if it is asymptomatic and an incidental finding. It could go under the umbrella of the odontogenic or nonodontogenic cyst or tumor. We present a well-defined, corticated, expansile, unilocular rad...
Central odontogenic fibroma (COF) isan extremely rare benign tumorthat accounts for 0.1% of all odontogenic tumors. It appears as an asymptomatic expansion of the cortical plate of the mandible or maxilla. Radiologically it presents as a unilocular or multilocular radiolucency. What is a complex...

Left lower lobe artery is invisible because it is in the atelec- tatic lobe; it is evident a small hilum. It is possible to see also the splaying of the blood vessels in the overexpanded left upper lobe. Lateral chest radiography (C) shows an increased opacity of the pos- terior ...
Atherosclerosis is a chronic inflammatory condition complicating cholesterol accumulation within the artery wall. Inflammation is believed to play an impor
IOPA of 43, 44, 45 region showed a well defined radiolucency with small sparse pebble like calcifications seen in between the radiolucency (Fig 2a). ADENOMATOID ODONTOGENIC TUMOR OF THE MANDIBLE - EXTRAFOLLICULAR VARIETY: A RARE CASE REPORT Iopa, AIA, is a principal with Watanabe Chun Iopa...
Choroidal melanoma tends to show echolucency, whereas metastasis, hemangioma, osteoma, lymphoma, and retinal tumors frequently exhibit echodensity. Mushroom configuration is most often associated with choroidal melanoma, but has been rarely observed with nonmelanoma lesions including retinoblastoma, hemangioma...
What is PARL in dental? Introduction: Neither the prevalence ofperiapical radiolucency(PARL), a surrogate for disease, nor the prevalence of non-surgical root canal treatment (NSRCT) in elders have been subjected to systematic review. What causes Radiolucency in teeth?
