Coronary artery anomalies are rare, and their incidence varies from 0.6% to 1.3%. Conventional angiography is a commonly used modality for the assessment of coronary artery anomalies, but it may not identify and define the anatomy of anomalous arteries due to the complexity of the course and three-dimensional orientation of the arteries. We present a rare case of duplicated right coronary arter...

Hemoptysis is the expectoration of blood that originates from the lower respiratory tract. It is usually a self-limiting event but in fewer than 5% of cases it may be massive, representing a life-threatening condition that warrants urgent investigations and treatment. This article aims to provide a comprehensive literature review on hemoptysis, analyzing its causes and pathophysiologic mechanis...

The advent of multislice computed tomography (CT) has revolutionised the performance of body CT and allowed the development of CT angiography (CTA). CTA is a robust and minimally invasive method of visualizing the arterial vascular system. The newer generation of multidetector scans has allowed for shorter scanning times with no respiratory misregistration at peak vascular opacification followi...

OBJECTIVE In this study, we evaluated the utility of 16-slice MDCT (multidetector computed tomography) to assess stent patency after coronary artery stenting. MATERIALS AND METHODS Retrospective ECG-gated CT-angiography using 16-slice MDCT was performed in 52 consecutive patients with coronary artery stents. Qualitative assessment of 61 coronary stent lumens by MDCT is reported, and the reaso...

O ne million patients undergo invasive coronary angiogra-phy (CA) in the United States every year. 1 In view of its invasive nature and related costs, noninvasive imaging of coronary imaging has the theoretical appeal to improve comfort for patients, reduce cost, and refine patient selection to limit invasive procedures to patients requiring treatment for ischemic coronary artery disease (CAD)....

BACKGROUND Coronary artery anomalies are evaluated by using catheter-based angiography. Multidetector row-computed tomography (MDCT) is a new noninvasive imaging technique that has excellent spatial resolution for detecting the origin and course of a coronary anomalous vessel. OBJECTIVE To determine the sensitivity of multidetector computed tomography in patients who had coronary artery anoma...

Splenic injury is a rare complication following colonoscopy with fewer than 100 reported cases worldwide to date. We describe a case of splenic laceration presenting 5 days following diagnostic colonoscopy. Although hemodynamically stable, active contrast extravasation on contrast-enhanced multidetector computed tomography predicted likely failure of conservative management. Splenic artery angi...

Coronary artery fistula arising from both the right coronary artery and the circumflex coronary artery is rare. A 28-year-old woman with non-insulin-dependent diabetes mellitus and end-stage renal disease who was on regular hemodialysis complained of recent progressive exertional dyspnea. Congestive heart failure was diagnosed during work-up for simultaneous kidney and pancreas transplantation....

Congenital coronary artery fistula (CAF) with huge coronary artery aneurysm is a very rare condition. In this paper, we describe a 26-year-old asymptomatic male patient with right coronary artery (RCA) to the left ventricle fistula with a huge coronary artery aneurysm which was diagnosed by multidetector computed tomography and coronary angiography. The patient received surgical treatment for c...

Hepatic adenomatosis (HA) is characterized by more than 10 adenomas in the liver, frequently scattered within both lobes. The potential for spontaneous bleeding, rupture, and malignant transformation is known. In HA, tumors show hypervascularization on arterial angiography, computed tomography (CT), and magnetic resonance imaging. We report the case of a 32-year-old woman who presented with a l...
