Gastric Ewing Sarcoma identified on a Meckel's scan.

Ewing Sarcoma is a malignant small round blue cell tumor most commonly found in bones and soft tissues of the axial skeleton and extremities. The Ewing family of tumors, including peripheral neuroectodermal tumor, represent the second most common malignancy in the pediatric population and second most common primary bone tumor after osteosarcoma. In a majority of Ewing Sarcoma cases, there is a translocation between chromosomes 11 and 22.

Exposure to, understanding of, and interest in interventional radiology in American medical students.

Rationale And Objectives: The purposes of this study were to determine the degree to which medical students are exposed to interventional radiology (IR) in medical school, to assess their knowledge of the field, and to gauge their interest in IR as a career choice.

Materials And Methods: An institutional review board-approved survey was generated using the website www.surveymonkey.

Spindle-cell sarcoma of the popliteal fossa mimicking a benign vascular lesion.

Spindle-cell sarcomas are a group of aggressive malignant soft-tissue tumors with diverse clinical presentations. While some of these tumors may represent de novo malignant transformation of benign entities, others may present with a long indolent course before their invasive nature is apparent. We report the case of a previously healthy 73-year-old female with spindle-cell sarcoma of the left popliteal fossa who initially presented with a painless mass of several months' duration.

Three dimensional active contours for the reconstruction of abdominal aortic aneurysms.

An aneurysm is a gradual and progressive ballooning of a blood vessel due to wall degeneration. Rupture of abdominal aortic aneurysm (AAA) constitutes a significant portion of deaths in the US. In this study, we describe a technique to reconstruct AAA geometry from CT images in an inexpensive and streamlined fashion.

An unusual complication of an infiltrated intravenous catheter: heterotopic ossification in a newborn.

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.
