Glossary

a non-progressive injury to the central nervous system occurring during gestation or in the perinatal period

Congenital heart disease.  A disorder or defect in the heart affecting blood circulation that is present at birth.  This can affect the heart’s valves, walls or its surrounding blood vessels.

Congestive heart failure. A chronic, usually progressive failure of the heart to pump an amount of blood needed by the body.  This results in a “back-up” of blood that in turn causes fatigue, shortness of breath, and a build-up of fluid or “edema” in the extremities, lungs and other locations.

of or resembling chitin (A tough, protective, semitransparent substance, primarily a nitrogen-containing polysaccharide, forming the principal component of arthropod exoskeletons and the cell walls of certain fungi.)

A specific type of involuntary, abnormal muscle contraction characterized by a sudden, rapid, jerking pattern 0f movement.

Choroid Plexus Papilloma

Cranial or Cephalic Index. The ration of the head’s width to its length. It is calculated by dividing the maximal head width by the maximal head length and multiplying the resulting quotient by 100.

Constructive Interference in Steady State: A MRI imaging technique that produces high-resolution  images. CISS accentuates the contrast between fluids, such as cerebrospinal fluid (CSF), and surrounding structures. This enables precise visualization of intricate structures within the nervous system, including the brain, spinal cord, and inner ear. Its ability to provide heavily T2-weighted images sets it apart as a valuable tool for detailing soft tissues and distinguishing fine structures.

Clivus-Vertebral Angle – Also termed the craniovertebral or clivi-canal angle is the angle of the intersection of line drawn along dorsal surface fo the clivus and the upper cervical ventral spinal canal. this angle is generally 150 deg or greater.

Involuntary, rhythmic muscle contractions due to a lesion of the upper motor neurons.  An extreme state of hyperreflexia.
