To examine the impact of the presence of facet tropism on the results of transforaminal epidural steroid injection for unilateral radicular pain induced by lumbar disc herniation. ⋯ Facet tropism correlates with less success of transforaminal epidural steroid injection; therefore, facet tropism may be a worthwhile measurement in a discussion with patients of the benefits of the procedure.

To evaluate the prevalence of isolated femoral head impactions associated with acetabular fractures and to assess whether impactions may be predictive of the development of delayed major complications requiring total hip arthroplasty. ⋯ Femoral head impactions are frequently seen on CT of patients with acetabular fractures; they are independent predictive factors for the need for delayed total hip arthroplasty. They should be systematically mentioned in the CT report.

Neoplasms of the sacrum are rare. Given the non-specific imaging findings in sacral lesions, the imaging-based differential diagnosis is always difficult. This case is about an adult with primary sacral neuroblastoma and we have discussed imaging and histopathological findings of this rare tumor.

Slipping rib syndrome (SRS) affects adolescents and young adults. Dynamic ultrasound plays a potential and likely significant role; however, limited data exist describing the protocol and techniques available. It is our intent to describe the development of a reproducible protocol for imaging in patients with SRS. ⋯ Dynamic ultrasound of the ribs, particularly with crunch and push maneuvers, is an effective and reproducible tool for diagnosing SRS. Valsalva plays a limited role. In addition to diagnosing SRS, ultrasound can give the surgeon morphological data and information on additional ribs at risk, thereby assisting in surgical planning.

To determine the value of low-dose whole-body CT (WBCT) in the management of patients with multiple myeloma (MM) and precursor states. ⋯ Whole-body CT provides important information for disease monitoring and detection of incidental findings, thereby improving the management of patients with MM.
