ABSTRACT
Multimodality imaging of the brachial plexus is essential to accurately localize the lesion and characterize the pathology and site of injury. A combination of computed tomography (CT), ultrasound, and MR imaging is useful along with clinical and nerve conduction studies. Ultrasound and MR imaging in combination are effective to accurately localize the pathology in most of the cases. Accurate reporting of the pathology with dedicated MR imaging protocols in conjunction with Doppler ultrasound and dynamic imaging provides practical and useful information to help the referring physicians and surgeons to optimize medical or surgical treatment regimens.

Chronic recurrent multifocal osteomyelitis is a rare noninfectious inflammatory bone disease diagnosed based on the synthesis of clinical, radiological, and pathological findings. The differential diagnostic considerations are led by multifocal infectious osteomyelitis and multifocal neoplasms. We report a case of a 9-year-old girl who emergently presented with worsening back pain, inability to walk, and normal vital signs. C-reactive protein and erythrocyte sedimentation rate were elevated, whereas the white blood cell count was normal. Initial radiographs and MRI of the spine showed multiple edematous vertebral body lesions. Subsequent whole-body MRI demonstrated multiple additional edematous bone lesions in the right half of the body, including the scapula, femur, and tibia. The lack of symmetrical bone lesion distribution indicated image-guided percutaneous core biopsy to exclude neoplastic disease. Pathological examination of an osseous core biopsy specimen showed a noninfectious osteomyelitis pattern with no findings of Langerhans cell histiocytosis, malignancy, or infectious osteomyelitis. The synthesis of clinical, radiological, and pathological findings was diagnostic of asymmetric right-sided chronic recurrent multifocal osteomyelitis, representing an atypical presentation that deviates from the typically symmetrical bilateral chronic recurrent multifocal osteomyelitis pattern.
