Purpose To identify the ability of computer-derived three-dimensional (3D) computed tomographic (CT) segmentation techniques to help differentiate lung adenocarcinoma subtypes. Materials and Methods This study had institutional research board approval and was HIPAA compliant. Pathologically classified resected lung adenocarcinomas (n = 41) with thin-section(More)
While most teratomas are asymptomatic, intrathoracic teratomas can rarely rupture spontaneously causing more alarming symptoms. Ruptured teratoma is a serious clinical entity, and early recognition is crucial for avoidance of further complications and preparation of proper surgical approach. We present a case of ruptured anterior mediastinal teratoma with(More)
Intraductal papillary mucinous neoplasms (IPMN) are being diagnosed with increasing frequency, necessitating an algorithm to help stratify patients into low- and high-risk groups, for follow-up versus more invasive evaluation. New evidence concerning their natural history and overall risk of malignancy has emerged since the 2006 International Association of(More)
As CT use steadily rises, concern over potential risks of radiation exposure from medical imaging has received increasing attention. Since May 2011, the ACR Dose Index Registry (DIR) has been open for general participation and has been collecting CT radiation dose data from an increasing number of facilities of various types. In this introductory review, we(More)
PURPOSE This study aims to compare tubular pancreatic ductal adenocarcinoma (tPDAC) and colloid subtype pancreatic ductal adenocarcinoma (cPDAC) associated with intraductal papillary mucinous neoplasms (IPMNs) on computed tomography. METHODS An institutional review board-approved retrospective study included patients with either IPMN tPDAC or cPDAC.(More)
Historically, cancer treatment has emphasized measures for the “cure” regardless of the long-term consequences. Advances in cancer detection and treatment have resulted in improved outcomes bringing to the fore various quality of life considerations including future fertility. For many young cancer patients, fertility preservation is now an integral(More)
Kawasaki disease is an acute, self-limited, febrile vasculitis typically seen in early childhood. Pulmonary involvement is uncommon and is not part of the conventional diagnostic criteria. We add to the literature a unique case of a 22year-old male with Kawasaki disease and pulmonary involvement. It illustrates the importance of recognizing unusual(More)
An 82-year-old Japanese nonsmoking man presented with persistent dry cough and small left apical pneumothorax. High resolution CT scan of the chest demonstrated bilateral upper lobe pleuroparenchymal thickening and architectural distortion. Serial imaging revealed mild progression and development of small bilateral pneumothoraces, and pneumomediastinum. A(More)
