The magnetic resonance imaging (MRI) appearance of an “established” bone marrow infarct is well-known, consisting of an area of preserved bone marrow signal surrounded by a serpiginous line. We report the uncommon observation of the very early phases of appearance of a bone marrow infarct, showing its progressive de novo appearance on MR images paralleling clinical symptoms and high-dose systemic steroid administration in a young female patient, presenting with acute knee pain. The initial knee MR examination performed one week after pain onset showed no abnormality. One week later, a second examination showed subtle ill-defined dotted signal abnormalities of the bone marrow of uncertain significance, of high signal on PDFS sequences. A third MR study obtained again one week later showed more evident findings with confluence of the high signal “dots” into a serpiginous line with a geographical appearance of the lesion, corresponding to the typical MRI presentation of bone marrow infarcts. Follow-up MRI at seven weeks showed definitive stability of this bone marrow infarct. A whole-body MRI performed for whole skeleton screening revealed multiple bone marrow infarcts typical for systemic avascular necrosis. This case represents a novel observation of the “birth” of a bone marrow infarct, from early intriguing changes to its typical ring-shaped appearance on MR images. It also reminds of the key role of MRI for early diagnosis of bone marrow infarcts and illustrates the emerging role of whole-body MRI for the detection of multifocal, asymptomatic skeletal involvement by ischemic lesions in systemic osteonecrosis.

Whole Body Mri

Recently, the assessment of the muscles using limb MRI and whole body MRI has become widely available and more frequent. In cases of muscular dystrophies it may help to select the optimal muscles for biopsy, because the severely atrophic and degenerated muscles are not suitable for histological tests. It is also known that the pattern of muscle involvement is characteristic for a certain neuromuscular disease, and clinically silent muscle damage can be visualized, as well. Therefore, imaging of muscles is helpful in neuromuscular differential diagnosis and planning genetic tests. Orv. Hetil., 2011, 152, 1362–1367.

AbstractWhole-body magnetic resonance imaging (WB-MRI) is a powerful tool increasingly used to assess oncologic and nononcologic diseases. WB-MRI provides information about diffuse multifocal pathologies with excellent anatomical definition through high soft tissue contrast and spatial resolution as well as valuable functional information from diffusion-weighted images. In addition to its roles in establishing the diagnosis and assessing the extent and severity of disease, WB-MRI is also useful for monitoring the response to treatment for malignant and benign systemic diseases affecting the musculoskeletal system. This article reviews and updates the applications of WB-MRI in current practice, discussing the role of this helpful tool in various conditions involving the musculoskeletal system including bone metastases, hematologic cancers, inflammatory processes, infections, and multisystemic-multifocal bone, nerve, vascular, and muscle/soft tissue disorders, as well as other idiopathic conditions.
