SUMMARY: Abnormally decreased T2/T2 FLAIR signal can be seen on brain imaging of patients who are experiencing clinical or subclinical seizures and can be associated with various intracranial pathologies. Bone marrow edema is typically a response to an injury such as a fracture or conditions such as osteoarthritis. The case shows a false-positive result of opposed-phase imaging of bone marrow, which was a postinflammatory cause resulting in marrow fibrosis that mimicked neoplastic marrow infiltration and necessitated biopsy for definitive diagnosis. Such a finding would not be expected with edema or inflammation, so biopsy was ordered. Our website services, content, and products are for informational purposes only. Normal bone marrow consists of cells that become red cells, white cells and platelets. The leukaemias typically affect the metaphyses > diaphyses > epiphyses.

Objective: Histiocytosis is a systemic disease that usually affects the central nervous system. Given that serial MRI was used to follow the case presented here, it provided an excellent opportunity to show a potential pitfall of opposed-phase imaging (also known as chemical shift imaging or in- and out-of-phase imaging) of the bone marrow. Permissions, Authors Their proportions are determined by the overall distribution of fat and water, which ultimately determines the magnetic resonance imaging (MRI) signal intensity. Tumors form when your body starts to produce too many plasma cells. This can lead to bone loss and a decreased ability to fight infections.

Since treatment is rapidly improving, its possible that survival rates are better than these figures indicate. 68,69. Changes of signal intensity in bone marrow are frequently observed in radiological routine and its diversity can cause a suspicion of pathologic findings.
