Bone marrow edema (BME) has been a topic of increasing interest in the literature in recent years. BME is associated with numerous pathologies and is becoming recognized not only as a considerable pain generator, but also as an entity which is, in some cases, significantly linked to the worsening of patient prognosis. To date, no thorough imaging review of BME has been published. ⋯ This presentation is a comprehensive discussion of different pathological conditions inducing or associated with BME. Differential diagnosis through appropriate imaging is vital to case management and could contribute to the prevention or decreased progression of certain pathologies. Continued investigation into the imaging of BME and its associated diseases, as well as the effect of BME on prognosis, is warranted.
