What does mass effect mean on head CT?

As the intracranial volume cannot change, any intracranial lesion which is ‘space-occupying’ may increase intracranial pressure and displace the soft tissues of the brain. This is known as ‘mass effect’. Intracranial pathological processes, such as masses and haemorrhage, can cause mass effect.

What is mass effect on head CT?

The local pressure from a tumor or bleeding (hematoma) on adjacent parts of the brain. Mass effect is diagnosed by an MRI or CT scan which shows where the mass is and what it is pushing on.

Does mass effect mean tumor?

In medicine, a mass effect is the effect of a growing mass that results in secondary pathological effects by pushing on or displacing surrounding tissue. In oncology, the mass typically refers to a tumor.

What does mass effect mean on cervical MRI?

Lesions or processes that cause compression, distortion, and/or displacement of intracranial contents may be said to have “mass effect.” One important concept to understand is that mass effect is a manifestation on imaging of various intracranial processes (including tumor, hemorrhage, ischemia, and trauma) and not a

What causes mass effect in brain?

As the intracranial volume cannot change, any intracranial lesion which is ‘space-occupying’ may increase intracranial pressure and displace the soft tissues of the brain. This is known as ‘mass effect’. Intracranial pathological processes, such as masses and haemorrhage, can cause mass effect.

What is mass effect on bladder?

A mass (tumor) that is found on the bladder – the muscular sac in the pelvic region that stores urine – can sometimes be indicative of bladder cancer.

How does Mass Effect present in a brain injured patient?

Mass effect is a phenomenon in which a focal lesion or contusion causes surrounding areas of brain tissue or brain structures to be compressed and injured due to the degree of space that leaking blood, cerebrospinal fluid, or edema takes up within the restricted skull space.

What does mass effect on spinal cord mean?

Spinal cord compression occurs when a mass places pressure on the cord. A mass can include a tumor or bone fragment. Compression can develop anywhere along the spinal cord from the neck to the lower spine.

What is mild Foraminal narrowing?

Foraminal narrowing is a specific type of spinal stenosis, a back condition that occurs when the open spaces within the spine narrow. The foramina are bony passageways located between the vertebrae in the spine.

What is disk protrusion?

Disc protrusion is a type of spinal disc herniation. Disc herniation is a common form of intervertebral disc damage that’s caused by age, natural wear and tear, traumatic accidents (falls, car accidents, sports collisions), overuse or repetitive use injuries, obesity and genetics.
