Glossary

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

Choroid Plexus Papilloma

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.

Capillary Malformation-Arteriovenous Malformation Syndrome.  A rare disorder involving small blood vessels (capillaries), usually of the face and limbs.  These lesions are typically 1-2 cm in diameter and multiple.  There can also be high-flow AVMs in the skin, muscle, bone and brain in this condition. These AVMs can result in bleeding, heart failure and neurologic deficits.

Compound motor (muscle) action potential. The composite electrical activity in a muscle that has been simultaneously stimulated by a group of motor neurons (nerve fibers) within a motor nerve.

Cystometrogram.  A diagnostic procedure used to evaluate bladder function.  It measures the pressure within the bladder as a function of the volume of fluid within the bladder.

Cytomeglovirus or human herpesvirus-5
