Apr 2, 2018 · This is a basic article for medical students and other non-radiologists. Intracranial mass effect describes what happens around a tumor in the brain. It is important to make the distinction between an abnormality that causes mass effect and compresses adjacent structures, and one that does not. Most tumors will cause mass effect on surrounding ...
Apr 21, 2023 · Mass effect is a general concept in pathology and radiology. Whilst it is most commonly encountered in the intracranial setting 1, it is certainly not restricted to the CNS. It can be used to describe any lesion in the body if it exerts displacement of adjacent structures, for example a musculoskeletal, abdominal or pelvic mass 2-4.

Intracranial pathological processes may cause mass effect - displacement or compression of the brain. Mass effect can be caused by intracranial masses, haemorrhage, and oedema. The brain is a soft tissue structure located inside the cranial vault: a finite space confined by bones of the skull. As the intracranial volume cannot change, any ...
Jan 22, 2016 · CHAPTER 4. Analysis of Mass Effect. 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 ...
Nov 2, 2023 · Mass effect in the brain is a term used in radiology reports. This term indicates that there is an abnormal space occupying lesion pushing on the brain. In this article, we will explore what mass effect in the brain means, why it’s important, and how it impacts our cognitive functions.
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 . For example, cancer of the thyroid gland may cause symptoms due to compressions of certain structures of the head and neck; pressure on the ...
Feb 15, 2020 · An informed differential diagnosis requires analyzing the imaging features in the context of the clinical presentation of the patient. A wedge-shaped cortical lesion, involving both gray and white-matter, presenting with an acute neurologic deficit is probably an ischemic infarction. Multiple cortical/subcortical round nodular enhancing lesions are likely metastatic. Large deep white-matter ...
