Magnetic resonance imaging (MRI) evaluation of pediatric elbow trauma with or without a visible fracture on radiography. ⋯ MRI is a sensitive and accurate method in the diagnosis of pediatric elbow injuries, especially when only an effusion is present on radiographs. Occult fractures are more common in pediatric patients with elbow injury than reported earlier.

Case Reports
PROPELLER diffusion-weighted magnetic resonance imaging of acute spinal epidural hematoma.
We present the case of an 86-year-old female with spontaneous spinal epidural hematoma. Although T1- and T2-weighted images showed the dilated posterior epidural space at the cervical spine, this finding was non-specific on conventional magnetic resonance imaging obtained 15 h after the onset of symptoms. Diffusion-weighted imaging with the use of periodically rotated overlapping parallel lines with enhanced reconstruction (PROPELLER), which clearly revealed the high intensity hematoma, was useful for detection and diagnosis of acute spinal epidural hematoma.

To evaluate a new adjunctive guidance device, a puncture guide, constructed to simplify computed tomography (CT)-guided punctures and to make the procedure more accurate and safe. ⋯ The benefits of the puncture guide were the artefact pointing at the target, the needle support, and accuracy when performing CT-guided punctures.

Bronchobiliary fistula (BBF) is a rare disorder consisting of a passageway between the biliary ducts and the bronchial tree. Many conditions may give rise to this development. Management of these fistulas is often difficult and can be associated with high morbidity and mortality rates. We present a case of BBF developing after hemihepatectomy in a 74-year-old man treated with endoscopic biliary drainage and illustrate MRCP findings.

Case Reports
Pneumomediastinum as a complication to treatment of mediastinal (thymic) large B-cell lymphoma.
Mediastinal (thymic) large B-cell lymphoma (Med-DLBCL) is a subtype of diffuse large B-cell lymphomas (DLBCL) with a typical radiological appearance of bulky anterior mediastinal mass, often with areas of necrosis. We report a case of Med-DLBCL with unusual radiological findings and clinical development. ⋯ To our knowledge, air-fluid levels inside Med-DLBCL have not been previously described. This finding, in combination with necrotic sputum, may indicate communication between the tracheobronchial tree and the tumor.
