Part 3 of a three-part series reviewing the effects of radiation on the brain. Join in on this grand finale as we review brain tumor development in a pilot who had logged many hours flying aircraft at high altitudes. High altitude pilots at the edge of the Earth's protective atmospheric shield, and astronauts just beyond it,... Continue Reading →
The most common tumors found in the central nervous system and dura (i.e. the dense fibrous covering that envelops the brain) are those that have traveled from other body sites in a process called metastasis. Depicted here is hepatocellular carcinoma (HCC), a cancer of liver cells, that has metastasized to the dura overlying the anterior pole of the right frontal lobe. Microscopically, the neoplastic liver... Continue Reading →
Not a trick of the eyes. This brain with a pronounced green discoloration belonged to an adult with marked jaundice due to acute and severe liver disease. Jaundice occurs when the blood carries higher than normal levels of bilirubin, a substance that is usually processed by the liver into bile which is then eliminated via the stool and urine. Liver disease... Continue Reading →
Meningiomas, like the one pictured here, typically show whorling architectural pattern and nuclear pseduoinclusions. The vast majority of meningiomas are low grade (WHO Grade 1) dura-based tumors with good prognosis following complete resection. However, recent studies have suggested that endothelial cell hypertrophy and/or microvascular proliferation in an otherwise typical meningioma are correlated with shorter progression free...
