MRI evaluation and follow-up of bone necrosis after meningococcal infection and disseminated intravascular coagulation.

Disseminated intravascular coagulation (DIC) is a serious complication of meningococcal septicaemia. It often results in infarction of various tissues namely the skin, adrenal glands, kidneys, brain and, much less commonly, bones. We describe a patient who presented bone lesions after meningococcal septicaemia. In addition to plain radiography and scintigraphy the lesions were evaluated with MRI and have proved to be extensive and still progressive, approximately 18 months after the onset of the disease.
