- A 3-year-old asymptomatic girl was noted to have a heart murmur. Chest X-ray showed a curvilinear shadow along the right heart border (Fig. 1A) characteristic of the Scimitar sign. Echocardiography revealed a Scimitar vein (SV) draining the entire right lung to the inferior vena cava (IVC) which was stenosed at the junction with SV (Fig. 1B; arrow). CT angiography and hepatic venography revealed a 1.5 cm-long segment of stenosis in the IVC proximal to the insertion of the SV, resulting in outflow obstruction of short hepatic veins (HVs) with resultant intrahepatic veno-venous collaterals which coursed to the IVC above the level of stenosis (Fig. 2).
- A 17-year-old female presenting to respiratory clinic with 4 months history of mild cough. Her physical examination is unremarkable. A chest radiograph showed a left-sided peri-hilar high-density tubular structure, thought to be a vascular malformation (Fig. 1). A computed tomography pulmonary angiogram (CTPA) revealed an unusual venous drainage of the left lung. The tubular structure was a meandering unilateral single pulmonary vein draining the left upper-lobe (Fig. 2a) then tortuously descending to cross the oblique fissure and join the left lower-lobe pulmonary vein before directly merging into the left side of the left atrium (Fig.
- A 49-year-old lawyer underwent an exercise test for an insurance physical. In recovery, he had frequent premature ventricular complexes and asymptomatic runs of monomorphic non-sustained ventricular tachycardia (NSVT) not preceded by ST segment shift or chest pain, suspicious for non-ischemic, anterior fascicular VT.
- Shone complex is a rare combination of valvular or supravalvular aortic stenosis, supra-valvular mitral membrane, parachute mitral valve, and coarctation of the aorta. This article presents an unusual case of a 40-year-old woman who presented with a history of progressive dyspnea. We describe the main imaging features and protocol used for visualizing this syndrome using various imaging modalities.
- We report the case of a 6 year old girl with Turner Syndrome and Aberrant Right Subclavian Artery with an incidental finding of PAPVR on contrast-enhanced, high-pitch, 128-slice, electrocardiographic-gated dual source CT. There is value of using high-pitch DSCT in pediatric patients for diagnostic images with minimal radiation exposure.
- Electrocardiographic-gated 64-slice multidetector computed tomography (MDCT) was performed on a 30-year-old man who presented with a complete endocardial cushion defect (ECD) and severe pulmonary hypertension diagnosed when he was 3 years old. Multiplanar reconstruction image showed the common atrium without an atrial septum, a large ventricular septum defect, and a small right ventricle due to a complete atrioventricular canal defect. Three-dimensional CT volume-rending imaging showed a patent ductus arteriosus, dilation of the ascending aorta, and an anomalous-origin right coronary artery.
- A 34-year-old woman with previous aortic coarctation repair at the age of 5 years was referred for review. She was in good health. On clinical examination, there was no blood pressure difference between the arms, but pedal pulses were weak. A contrast-enhanced 64-slice thoracic CT scan was performed to assess the coarctation repair.
