Angiomatoid fibrous histiocytoma (AFH) is a rare soft tissue tumor most commonly occurring in children, adolescents, and young adults. Clinically and radiographically the lesion is easily confused with a hematoma, soft tissue hemangioma, or malignant fibrous histiocytoma. While the lesion is rare, due to the potential for local recurrence and metastasis, it(More)
OBJECTIVE The purpose of this study was to describe the clinical, imaging, and surgical findings in the cases of four neonates with radiographic findings suggesting duodenal atresia (double-bubble sign) who were subsequently found to have malrotation with midgut volvulus. CONCLUSION When the surgical treatment of a patient with the double-bubble sign is(More)
PURPOSE To determine the accuracy of unenhanced magnetic resonance (MR) imaging in the detection of acute appendicitis in patients younger than 50 years who present to the emergency department with right lower quadrant (RLQ) pain. MATERIALS AND METHODS The institutional review board approved this retrospective study of 403 patients from August 1, 2012, to(More)
OBJECTIVE A meta-analysis was performed to determine the accuracy of MRI in the diagnosis of acute appendicitis in the general population and in subsets of pregnant patients and children. MATERIALS AND METHODS A systematic search of the PubMed and EMBASE databases for articles published through the end of October 2014 was performed to identify studies(More)
Heterotopic ossification refers to formation of lamellar bone in soft tissues. The etiology is diverse and includes genetic, post-traumatic, and metabolic causes. Elicitation of bone morphogenic proteins are thought to play a key role in the pathogenic process. Initially, heterotopic ossification presents a clinical and radiographic challenge in that it can(More)
Properly placed central venous catheters have been effective in establishing prolonged access for total parenteral nutrition infusion in ill neonates. However, malposition of the catheter may lead to lethal complications. Malposition and infusion into the epidural venous plexus is most commonly diagnosed on the basis of radiographs and has been confirmed by(More)
OBJECTIVE Radiologists are taught that pyogenic osteomyelitis in children rarely crosses the growth plate because terminal vessels of nutrient arteries loop at the physis, predisposing the metaphysis to hematogenous infection. However, we note that MRI frequently shows osteomyelitis involving both sides of the physis. The purpose of this article is to(More)
We report the case of a 16-year-old female with genetic immunodeficiency in whom pulmonary coccidioidomycosis became disseminated. Most infections due to Coccidioides immitis are self-limited and resolve over a period of weeks to months without specific treatment. In rare cases, especially those associated with immunodeficiency, the disease is found outside(More)
