BACKGROUND AND PURPOSE The falcine sinus has been considered as a rare variation of the venous pathway between the dural layers of the falx cerebri. The purpose of this study was to evaluate the incidence of falcine sinus and its anatomic characteristics by using CTA. MATERIALS AND METHODS A total of 586 consecutive patients were enrolled in this study. A falcine sinus on CTA was defined as a...
Introduction Wolff-Parkinson-White (WPW) syndrome is characterized by a short PR interval, wide QRS complex, and paroxysmal supraventricular tachycardia. An accessory atrioventricular connection is known to be the underlying mechanism of this syndrome. Accessory pathways (APs) are mainly located along the tricuspid or mitral annulus, accounting for 10%– 20% and 50%–60% of cases, respectively. M...
Persistent left superior vena cava (PLSVC) is rare but important congenital vascular anomaly. It results when the left superior cardinal vein caudal to the innominate vein fails to regress. It is most commonly observed in isolation but can be associated with other cardiovascular abnormalities including atrial septal defect, bicuspid aortic valve, coarctation of aorta, coronary sinus and ostial ...
We present a case of an incidentally discovered holohemispheric developmental venous anomaly (DVA) in a 12 year old, conclusively characterized by 3D T2* multi-echo sequence susceptibility weighted angiographic imaging (SWAN). For the evaluation of head trauma, abnormal right intraparenchymal and periventricular vascularity was identified by a non contrast head CT scan. Conventional MRI sequenc...
PURPOSE To report 5 cases of orbital lymphangioma. METHODS All patients underwent ophthalmological, clinical and neuroradiological evaluation. RESULTS At presentation all patients (4 children and one adult patient) had unilateral proptosis. Restricted eye movement was present in 3 patients, ptosis and amblyopia in 2. Compressive optic neuropathy with visual loss was noticed in one patient. ...
Persistent left superior vena cava (PLSVC) is a congenital anomaly of the thoracic venous system resulting from the abnormal persistence of an embryological vessel that normally regresses during early fetal life. This anomaly is often discovered incidentally during surgery, cardiovascular imaging or invasive cardiovascular procedures. In most cases, a PLSVC drains into the right atrium through ...
Abnormal connection of the right superior caval vein to the left atrium is an uncommon systemic vein drainage anomaly, with only a few cases reported among congenital heart disease (CHD), around 20 cases published in the medical literature. The inferior vena cava connection with the left atrium, also very rare, can appear directly or in heterotaxy. Clinical suspicion arises due to the presence ...
A 21-year-old man with a history of Ebstein anomaly and atrial fibrillation who had previously undergone tricuspid valve repair, pulmonary venous isolation, and the Cox maze III procedure was referred from an outside institution for the evaluation of an acute onset of left-sided upperand lower-extremity weakness. The patient had initially presented 3 years earlier with abdominal pain and sympto...
Background Heterotaxy syndrome (HS) is characterized by a wide variety of cardiac and extra-cardiac malformations, including pulmonary valve stenosis, interruption of the inferior vena cava, total anomalous pulmonary venous connection (TAPVC), asplenia, polysplenia, intestinal malrotation, and preduodenal portal vein (PDPV). We report the case of a heterotaxic infant with an infracardiac TAPVC ...
Cor Triatriatum Sinistrum is a congenital anomaly in which the left atrium is divided into 2 parts by a fold of tissue, a membrane, or a fibromuscular band. Classically, the proximal (upper or superior) portion of the left atrium receives the venous blood, whereas the distal (lower or inferior) portion is in contact with the atrioventricular valve and contains the atrial appendage and the true ...
