Hyperdense (more dense): If an abnormality is bright (white) on CT , we describe it as hyperdense. On the image above, both arrows point to areas of hyperdensity. The solid arrow points to an area of right frontal and parietal intraparenchymal hemorrhage. The dashed arrow points to blood in the left lateral ventricle.

This is easy to appreciate because part of the lesion is extrarenal. The cystic lesion next to it is totally intrarenal, which makes it harder to appreciate, but there is wall tickening. So both lesions have to be excised, whether there is enhancement of the wall or not. hyperdense brain lesion.

Lesions 1-2 cm in patients without cancer history are probably benign. You may consider 12 month FU. In all other indeterminate lesions perform a dedicated adrenal CT or MRI to diagnose lipid-poor adenomas. These need no follow up. If the lesion is not a lipid-poor adenoma, the …

During a CT scan, this area will light up, but the finding of a hypodense mass does not necessarily indicate tumors or cancerous lesions. Instead, it means that the color of the scan had changed to indicate the presence of some type of mass. In contrast to typical astrocytic tumors that show hypodense areas on computed tomographic images, some intracranial tumors show hyperdense areas on CT images. The major reasons for hyperdensity on CT images are hypercellular lesions, intratumoral calcification, and intratumoral hemorrhage. The diagnosis and management of these radiopaque/hyperdense lesions could be challenging to the endodontist. These bone alterations could be neoplastic, dysplastic or of metabolic origin.

The appearance consists of a lucent nidus that is sometimes calcified, associated with surrounding sclerosis. The typical triad of pain, worse at night and relieved by salicylates, is seen in 30%–50% of patients with osteoid osteoma. Lesions are common in the femur and tibia.
