Radiation-Induced Maxillary Osteosarcoma and Synchronous Oropharyngeal Squamous Cell Cancer: A Rare Case Report

Lale Pasaoglu, Dinara Mamedova, Ugur Toprak and Gul Hatipoglu

Article Type: Case Report | First Published: April 21, 2017

Radiotherapy is a treatment option for nasopharyngeal cancer. However, ionizing radiation may lead to development of secondary malignancies. In this case report, we will present a case of radiation-induced osteosarcoma of the maxilla and synchronous oropharyngeal squamous cell cancer following treatment of nasopharyngeal cancer. History, latency period, physical examinations, computed tomography, magnetic resonance imaging and biopsy results are provided....

Aggressive Angiomyxoma: Two Case Reports and Review of the Literature

Min Cao, Ying Gao, Xiaoying Wang and Xuedong Yang

Article Type: Case Report | First Published: April 17, 2017

Aggressive Angiomyxoma (AA) is a kind of rare, low grade myofibroblastic neoplasm with high risk of local recurrence mainly for the character of locally aggressive and misdiagnosis as other soft tissue mass in the pelvis. The "laminated or swirled sign" of swirled strands of low-signal intensities in T2WI is the diagnostic sign for the layered configuration of AA....

Does Improved Technology in SPECT Myocardial Perfusion Imaging Reduce Downstream Costs? An Observational Study

Nicholas D Patchett, Sumeet Pawar, Aaron Sverdlov and Edward J Miller

Article Type: Original Research | First Published: February 25, 2017

Advances in myocardial perfusion imaging (MPI), including CT attenuation correction (CTAC) and advanced image reconstruction algorithms, result in improved image quality, thus reducing equivocal or false positive results. This theoretically decreases the need for downstream testing; however, there is limited access to these technologies due to their costs and the magnitude of benefit remains unclear. ...

Comparison of Arterial Spin Labeling and Dynamic Susceptibility Contrast-Enhanced MR Perfusion in Differentiating Tumor Recurrence from Treatment-Related Changes

Robert J Bert, William Colantoni III, Douglas E Ney, Denise M Damek, Bette K Kleinschmidt-DeMasters and Manuel Thomas Borges

Article Type: Original Research | First Published: February 24, 2017

MR dynamic susceptibility contrast-enhanced perfusion (DSC) has demonstrated utility in the evaluation of follow-up malignant CNS neoplasms. Preliminary studies suggest Arterial Spin Labeling (ASL) perfusion may be equivalent for this purpose. Using a retroprospective, blinded test design, we compared interpretations of ASL and DSC in tumor follow-up....

Inferior Mesenteric Arteriovenous Malformation Presenting as Ischemic Colitis After an Acute Episode of Campylobacter Jejuni Colitis

Roy Hajjar, Patrick Gilbert, Marie-France Giroux, Frank Schwenter and Herawaty Sebajang

Article Type: Case Report | First Published: January 12, 2017

An arteriovenous malformation (AVM) of the inferior mesenteric artery is a rare entity that could be associated with ischemia. We present the case of a 54-year-old male with ischemic colitis after an acute episode of Campylobacter jejuni colitis. A computed tomography (CT) angiography confirmed the presence of an AVM in the inferior mesenteric vascular region, probably causing the ischemia through a steal phenomenon. ...

The Utility and Inter-Reader Agreement in the Evaluation of Pediatric Liver Masses with Hepatobiliary Contrast Enhanced MRI

Hansel J Otero, Asef B Khwaja, Maria A Bedoya, Nancy Chauvin, Kassa Darge and Sudha A Anupindi

Article Type: Original Research | First Published: January 09, 2017

22 patients with liver lesions evaluated on Gd-EOB-DTPA-enhanced MRI were selected. Two reviewers assigned a diagnosis and stratified the hepatobiliary images as: 1) High utility; 2) Potential utility; or 3) No utility. 95% of assigned diagnoses were correct with almost-perfect agreement (κ = 0.92). Hepatobiliary images were deemed useful by at least one reviewer in 82% cases with moderate agreement (k = 0.48)....
