Necrosis means tissue has died, often because of poor blood supply, severe infection, injury, or aggressive disease.
Symptoms depend on where the tissue damage is and may include severe pain, swelling, fever, skin color change, discharge, or worsening organ-related symptoms.
Imaging helps show where tissue has died, how extensive it is, and whether there are complications such as infection, gas, fluid collection, or organ damage.
Imaging may show non-enhancing tissue, breakdown, gas, or structural destruction depending on the organ involved.
Treatment focuses on the underlying cause and may include urgent medical care, drainage, surgery, or organ-specific treatment.
