Editor: Large hepatic cysts may cause abdominal distension and tenderness, symptoms that can be relieved by reduction of the cyst volume. Sclerotherapy with absolute ethanol has been widely performed as a minimally invasive treatment for symptomatic hepatic cyst. We report a case of recurrent symptomatic hepatic cyst treated successfully with cyanoacrylate(More)
Complete occlusion of arteriovenous shunt is a feared complication of hemodialysis due to limited vessels suitable for reconstruction of arteriovenous shunt. For prolonged use of the arteriovenous shunt, there are many methods for restoring the function of the occluded arteriovenous shunts. So far the standard treatment for complete occlusion of(More)
We reviewed the unenhanced computer tomography (CT) scans of 53 patients with surgically proven acute cholecystitis, where 27 patients presented with hyperdense gallbladder wall. To our knowledge, this sign was never reported before. Because mucosa is highly sensitive to ischemia, early mucosal necrosis and hemorrhage may result in CT-detectable high(More)
The purpose of this study was to evaluate the presence of the hyperdense appendix in acute appendicitis. The CT scans of 183 patients with pathologically proven acute appendicitis were reviewed to determine the prevalence of a hyperdense appendix, defined as a high-attenuated appendix when compared with the adjacent cecal wall on precontrast CT. A control(More)
Urinary bladder paraganglioma is a very rare tumor, account for <0.05% of all bladder tumors. They are usually submucosal tumors most commonly located near the urinary bladder trigone. A deeply located urinary bladder paraganglioma may not be seen on cystocope, and pelvic sidewall paraganglioma may mimic urinary bladder paraganglioma. Here we present an(More)
Intussusception of the appendix is rare in worldwide studies and is difficult to recognize before operation. We report a case of a 58-year-old, previous healthy male with defecating tarry stool for 10 days with dizziness, general weakness. Double contrast colon series and abdominal computed tomography (CT) revealed a 2.5 cm pedunculated, polyp-like lesion(More)
Parachordoma is an extremely rare entity and there are only about 50 to 60 cases reported, in which there is only one definite pelvic parachordoma. We present a huge well-defined presacral tumor in a 48-year-old woman who has the symptoms of lower abdominal pain and difficulty in defecating. Radiological findings of the tumor on computed tomography and(More)
