Musculoskeletal manifestations of sickle cell disease, diagnosis with whole body MRI

Purpose: The aim of work is to define the musculoskeletal abnormalities in patients with sickle-cell disease using whole body MRI. Patients and methods: Twenty-seven patients with known sickle cell disease were included in this study complaining of acute painful vaso-occlusive crisis. All the patients complaining of bony pain in different body regions. Some patients complaining of bony swellings and joint pain. Whole body (W.B) MRI studies were performed for all the patients. Three coronal (T1, T2, and STIR) sequences were performed for whole-body MR imaging. In selected cases, dedicated examination of certain body parts was performed. Results: Persistent red marrow, intramedullary bone hyperplasia and bone infarcts were seen in all patients. Vertebral bone infarcts were found in 23 patients. Bilateral proximal femoral head epiphysis avascular necrosis were found in 9 patients. Osteomylitis was diagnosed in 6 patients and septic arthritis in 2 patients. Conclusion: Whole body MRI can help identifying muscloskeletal abnormalities in sickle cell disease in a single session. MRI is a useful imaging tool in distinguishing acute osteomylitis and bone infarct. Knowledge of the range of imaging findings is crucial in order to accurately depict the complication and initiate appropriate therapy. (C) 2011 Egyptian Society of Radiology and Nuclear Medicine.
