myonecrosis
Noun: - Localized death of muscle cell fibers: Myonecrosis refers to the pathological condition where muscle tissue in a specific area dies. This is often caused by a severe lack of blood supply (ischemia), infection (such as in gas gangrene), toxins, or direct physical trauma.
The term is used in medical and scientific contexts to describe a specific type of tissue damage. - The patient developed myonecrosis following the compartment syndrome. - Clostridial infections can lead to rapid myonecrosis. - The MRI scan confirmed areas of myonecrosis in the heart muscle after the infarction.
- As a diagnostic finding: The term is often used in diagnostic reports, pathology, and medical literature to specify the nature of tissue damage.
- The biopsy results indicated extensive myonecrosis, consistent with the clinical diagnosis of necrotizing fasciitis.
- Necrosis (n): The death of most or all of the cells in an organ or tissue due to disease, injury, or failure of the blood supply. Myonecrosis is a specific subtype of necrosis.
- Rhabdomyolysis (n): A condition involving the rapid breakdown of damaged skeletal muscle, which can lead to complications. While related, rhabdomyolysis involves the release of muscle contents into the bloodstream and is not synonymous with the localized tissue death described by myonecrosis.
- Muscle necrosis: A direct synonym.
- Ischemic muscle death: Describes myonecrosis specifically caused by lack of blood flow.
Myonecrosis specifically denotes the death of muscle fibers. It is distinct from general tissue death (necrosis) or the death of other specific tissue types (e.g., hepatonecrosis for liver, osteonecrosis for bone). The "myo-" prefix explicitly ties the condition to muscle tissue.
- localized death of muscle cell fibers
