Cognard Type V dural arteriovenous fistulas (dAVFs) are a unique type of cranial vascular malformation characterized by congestion of the perimedullary venous system that may lead to devastating spinal cord pathology if left untreated. The authors present the first known case of a pediatric patient diagnosed with a Type V dAVF. A 14-year-old girl presented with a 3-week history of slowly progressive unilateral leg weakness that quickly progressed to bilateral leg paralysis, sphincter dysfunction, and complete sensory loss the day of her presentation...

Transhiatal herniation of the pancreas is rare. Acute pancreatitis secondary to this phenomenon is particularly unusual. A 102-year-old woman presented with 1 day of severe chest pain, vomiting, dyspnea, and diaphoresis. Serum lipase was elevated, and computed tomography angiogram of the chest and magnetic resonance cholangiopancreatography revealed a hiatal hernia containing the pancreas, with associated findings of pancreatitis. Pancreatitis in this setting may be due to repetitive trauma or ischemia from sliding, intermittent folding of the pancreatic duct, or pancreatic incarceration...

BACKGROUND: Assessment of lung function is vital for the diagnosis of a variety of pathological conditions. Research has been proposed to study pulmonary mechanics and kinematics using two-dimensional (2D) magnetic resonance imaging (MRI). This allows estimation of regional lung tissue mechanics but is limited to 2D information. An approach based on three-dimensional (3D) contrast-enhanced MR angiogram of pulmonary blood vessels and a non-rigid image registration technique is proposed for quantification of lung regional deformations, which can potentially be used for assessment of pulmonary parenchymal mechanics and regional ventilation for disease diagnosis without ionizing radiation...

Anomalies of the coronary arteries are reported in 1-2% of patients among diagnostic angiogram. Dual origin of a circumflex from both sinuses is extremely rare among them. We report a case of a patient who underwent primary percutaneous coronary intervention for acute inferior wall myocardial infarction where left coronary injection demonstrated normal obtuse marginal and right coronary injection demonstrated normal right coronary artery (RCA). On further probing, an anomalous left circumflex (LCx) artery was seen arising from RCA ostium which was subsequently cannulated and revascularized by deployment of 2...

Percutaneous coronary intervention is a minimally invasive procedure that is usually performed under image guidance using X-ray angiograms in which coronary arteries are opacified with contrast agent. In X-ray images, 3D objects are projected on a 2D plane, generating semi-transparent layers that overlap each other. The overlapping of structures makes robust automatic information processing of the X-ray images, such as vessel extraction which is highly relevant to support smart image guidance, challenging. In this paper, we propose an automatic online layer separation approach that robustly separates interventional X-ray angiograms into three layers: a breathing layer, a quasi-static layer and a vessel layer that contains information of coronary arteries and medical instruments...

Case report of the male with an anterior STEMI to whom a primary PCI is performed. The angiogram shows a fluctuating close of the LAD and Cx than when an OCT is performed does not clearly see any pathological findings but when the IVUS is performed, it is clearly seen as a coronary haematoma at the LM, LAD and Cx. Stent at the LM-LAD and proximal Cx are implanted with final good result. After exchanging the guiding catheter for a diagnostic catheter to visualize the RCA, there is an aortic flap; the coronary haematoma was coming from an ascending aortic dissection...

INTRODUCTION: While acute myocardial infarction  (AMI) mostly is a disease of the elderly it also affects younger individuals, often with serious consequenses. In 1980-1984 a study was carried out on the incidence, risk factors, infarct location and distribution of atherosclerosis among Icelanders forty years and younger with AMI. Here we present the results of a similar study carried out for the five year period 2005-2009. MATERIALS AND METHODS: Medical and autopsy records of all individuals, forty years and younger, diagnosed with AMI (I21 in ICD-10) at Landspitali, National University Hospital 2005-2009, or suffering sudden cardiac death in Iceland during the same period were reviewed...

The following report describes the case of a 43-year-old male smoker that was referred to the rapid access lung clinic with haemoptysis, chest pain, and axillary lymphadenopathy-a clinical picture that raised concern for a possible underlying malignancy. Preliminary investigations revealed elevated D-dimers, low-volume haemoptysis, and a normal chest X-ray, which lowered the index of suspicion. However, computed tomography (CT) pulmonary angiogram identified a right hilar mass, several parenchymal cysts, and a large mediastinal mass...
