What is reactive marrow changes?

Reactive marrow changes refer to alterations in the bone marrow's cellular composition and structure in response to various stimuli, such as infection, inflammation, anemia, or other stressors. These changes may include increased production of blood cells or alterations in the types of cells present, reflecting the body's attempt to compensate for underlying issues. Such changes can be observed through imaging or biopsy and are often indicative of the body's adaptive responses to pathological conditions.
