Acute elbow trauma in children: role of ultrasonography.

Background: The diagnosis of occult elbow fracture in children is often challenging due to equivocal or negative repeated radiographic findings.

Objective: To evaluate the potential diagnostic role of US in children who have sustained elbow trauma with an elbow joint effusion but no fracture seen on initial radiographs.

Materials And Methods: The study included 14 consecutive children (age range 5-15 years) with elbow trauma whose elbow radiographs showed an effusion without fracture who underwent emergency imaging (within the first 72 h) with US and MRI.

[Diagnosis of thoracic outlet syndrome. Value of angiography in the sitting position].

Purpose: Thoracic outlet syndrome includes arterial, venous or neurological symptoms. Frequently difficult to diagnose clinically, confirmatory imaging studies are usually required. The purpose of this study is to review the diagnostic work-up during management of patients with thoracic outlet syndrome and demonstrate the value of angiography in the sitting position.

[Traumatic complete isthmic rupture of horseshoe kidney].

The authors report the case of a 14-year-old boy with complete isthmic rupture of a horseshoe kidney after a bicycle accident. The imaging diagnosis was difficult because of the presence of a massive retroperitoneal haematoma. However, sonography and CT should be sufficient to detect associated signs, such as malrotation of the renal hila and low-lying kidneys.

[Intramedullary metastases and syringomyelic cavities].

Intramedullary metastases from a non neurogenic cancer are relatively rare, representing approximately 1-2,1% of metastatic sites according to published autopsy reports. Their association with syrinx is extremely rare. Four cases have been described in the last 30 years.
