Pulmonary atresia with ventricular septal defect (PA-VSD) is a rare complex congenital heart defect. Major artery-pulmonary collateral arteries (MAPCAs) are characteristic of PA-VSD. Prenatal diagnosis can be achieved in most cases of PA-VSD with recent advances in echocardiograp...

Typical myxomatous fibroadenomas have a small depth/width (D/W) ratio on ultrasonography. The small D/W ratio of fibroadenomas is speculated to be caused by the softness of the mass and its orientation along the longitudinal aspect of the ductal elements without adhesion to the s...

Aneurysms of the sinus of Valsalva are characterized by dilatation of at least one of the three aortic sinuses. We experienced a case with unruptured aneurysm of the right sinus of Valsalva, in which serial imaging studies were useful in assessing a rare complication after surgic...

We report a monochorionic diamniotic twin pregnancy with prenatal diagnosis of aortopulmonary septal defect combined with type B interrupted aortic arch in one of the fetuses. The mother was referred for fetal echocardiography at 24 weeks’ gestation due to suspected congenital he...

Purpose Tolvaptan is the first approved treatment for autosomal dominant polycystic kidney disease (ADPKD) that targets a mechanism directly contributing to the development and growth of renal cysts. We investigated the ability of ultrasonography to predict total kidney volume (T...

Aneurysms of the left main coronary artery are rare and their optimal treatments remain unknown. A 64-year-old man without any symptoms was referred to our department for suspected coronary aneurysm. Transthoracic echocardiography demonstrated an aneurysm of the left main coronar...

A patient with slight dilatation of the main pancreatic duct was followed-up with ultrasonography every 6 months as a high-risk case of pancreatic cancer. Twelve years later, a faint hypoechoic area 13 mm in diameter was first detected on the body of the pancreas. Contrast-enhanc...

In recent years, ultrasonography has become increasingly precise in diagnosing abdominal and gastrointestinal diseases. In most cases, a definitive diagnosis for acute appendicitis, which is commonly encountered in daily practice, can be obtained by using ultrasound. In addition,...
