Sometimes when the spaces between the vertebrae (spine bones) become narrowed, the nerves that exit through these openings can get compressed (pinched or impinged) causing pain, numbness, tingling or weakness.

A lesion is an abnormality seen on an imaging test. A bone lesion may involve small to large areas of your bone(s) and the severity of the underlying condition may range from relatively minor to life-threatening. These lesions will need further work up to for a diagnosis.

An infarct (short for infarction) is a stroke caused by an interruption of a healthy blood supply to the brain. Old infarcts are not reversible. They are most commonly caused by the same risk factors that cause heart disease, including high blood pressure, poor cholesterol levels, diabetes, smoking and sometimes emboli (small particles such as blood clots or plaque that traveled from other parts of the body).

A brain lesion is an abnormality seen on a brain-imaging test. A brain lesion may involve small to large areas of your brain, and the severity of the underlying condition may range from relatively minor to life-threatening. These lesions will need further work up to for a diagnosis.

A lesion is an abnormality seen on a lung-imaging test. A lung lesion may involve small to large areas of your lung(s), and the severity of the underlying condition may range from relatively minor to life-threatening. These lesions will need further work up to for a diagnosis.

The pancreas is a long, flat gland that sits tucked behind the stomach in the upper abdomen. Its main function is to produce enzymes that help with digestion and hormones that help regulate the way the body processes sugar. Intraductal papillary mucinous neoplasm (IPMN) is a precancerous lesion of the pancreas with risk of developing into cancer over time.

The intrahepatic biliary duct is a tube that is inside the liver and transports bile in the liver. Dilatation is the expansion or widening of the duct. Dilatation of the bile duct can be due to several causes including obstruction (blockage) of the bile duct, presence of a cyst or mass in the bile duct, benign (non-cancerous) strictures or infection. Symptoms, if present, could include right upper quadrant pain and/or jaundice.

A Killian-Jamieson diverticulum, a rare type of esophageal diverticulum that develops as a protrusion of mucosa (the membrane that lines the inside of the GI tract) through a muscular defect/weakness in the esophagus.

Iron is an important nutrient that helps the hemoglobin in blood cells carry oxygen to the body's organs and tissues. Iron overload (hemochromatosis) is a disorder in which the body has too much iron build-up. This extra iron is stored in the joints and organs; if this process is not controlled, it can cause joint and organ damage and/or failure.

The intrahepatic biliary duct is a tube that is inside the liver and transports bile in the liver. Dilatation is the expansion or widening of the duct. Dilatation of the bile duct can be due to several causes including obstruction (blockage) of the bile duct, presence of a cyst or mass in the bile duct, benign (non-cancerous) strictures or infection.
