We encountered a 69-year-old woman displaying a filling defect within the left descending pulmonary artery (PA) on a chest CT scan and pulmonary angiography. A subsequent 2-[18F]fluoro-2-deoxy-D-glucose (FDG) positron emission tomography (PET) scan demonstrated focal uptake in the left hilum. A cytologic examination of transbronchial needle aspiration specimens revealed small cell carcinoma. Th...

Noninvasive detection of coronary artery stenosis with noninvasive imaging modalities (electron beam CT, MR angiography) has recently emerged. The use of helical CT in the visualization of epicardial coronary arteries is limited by cardiac motion artifacts due to long acquisition times and lack of an ECG trigger and is therefore reliable only in the determination of coronary graft patency. With...

Chronic totally occluded coronary arteries are frequently found in symptomatic patients undergoing diagnostic coronary angiography. However, the presence of such an artery has a significant impact on choice of revascularization treatment. This case report shows the potential of preprocedural multislice computed tomography coronary angiography in guiding percutaneous revascularization of chronic...

Castleman’s disease is an uncommon lymphoproliferative disorder, which occurs most commonly in the mediastinum. Sporadic reports of its occurrence in the hepatoduodenal ligament, and other extrathoracic locations have also been documented. Ultimately, Castleman’s disease can develop anywhere lymphoid tissue is found, and the preoperative diagnosis is often difficult. We report a case of hyaline...

Angiographically occult cerebrovascular malformation (AOVM) is a type of complex cerebrovascular malformation that is not visible on digital subtraction angiography (DSA). Vascular malformation coexisting with glioma is clinically rare, and glioma coexisting with AOVM is even more rare. To the best of our knowledge, the present study is the first to report glioma coexisting with AOVM in the lit...

A 57 year old female presented with acute onset headache started from 1 month before the current visit. The headache was located on the left frontotemporal area and had increased during the month. On brain CT scan, there were bilateral round hyperdense lesions in the sylvian fissure which were flow void on brain MRI indicating aneurysms. Brain DSA (digital subtraction angiography) was performed...

conclusions performing routine chest and abdominopelvic ct-scan in conscious blunt trauma patients decreases the hospitalization time but has no effect on patient complications and final outcome. using a selective approach and performing ct-scan only for symptomatic patients, would be an appropriate option to decrease radiation dose and facility overuse. nevertheless, the concern of missing occ...

we report the case of a three-year-old girl who complained from dysphagia and post-prandial vomiting since she was 6months old. several diagnostic work-ups were performed for her problem. upper gi endoscopy was normal but barium swallow revealed an external pressure effect over upper part of the esophagus (figure 1) and the ct angiography of thoracic aorta showed that this external pressure eff...

cardiovascular disease remains the principal cause of death in the modernized world.   several novel noninvasive imaging techniques have been recently developed to improve diagnosis of cardiac and coronary disease.   of these advances, multidetector computed tomographic (mdct) angiography has evolved most dramatically to transform computed tomography from a single-slice trans-axial modality to ...
