Two Cases of Retroperitoneal Liposarcoma Diagnosed Using Endoscopic Ultrasound-Guided Fine-Needle Aspiration (EUS-FNA)
This report describes our experience with two cases that were ultimately diagnosed as retroperitoneal liposarcoma using endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA). Case 1 is that of a 54-year-old woman with chief complaints of nausea and abdominal distention. Computed tomography (CT) and magnetic resonance imaging (MRI) revealed a large (15 cm diameter) tumor, which was signi...
متن کاملEUS-FNA for the Diagnosis of Retroperitoneal Primitive Neuroectodermal Tumor
Primitive neuroectodermal tumor (PNET) is a rare "small round blue cell tumor" that is diagnosed by open biopsy or percutaneous biopsy of the lesion under radiologic guidance. In this case report, we present a novel approach to the diagnosis of a retroperitoneal PNET by endoscopic ultrasound- (EUS-) guided fine needle aspiration (FNA). A 35-year-old man presented with the history of left-sided ...

متن کاملEUS Guided Pancreatic Duct Drainage: When? How?
Despite advances in endoscopy, EUS-guided pancreatic duct drainage (EUS-PDD) remains a technically challenging procedure. There is still a high rate of adverse events ranging from 15-60% and the procedure can be life threatening. Until recently, a significant difficulty with this technique was the absence of dedicated devices. Proper patient selection is of utmost importance; EUS-PDD should be ...
متن کاملWhen Can Martingales Avoid Ruin?
We provide conditions that guarantee for a discrete time martingale Mn, either limn→∞Mn exists, or both lim supn→∞Mn = ∞ and lim infn→∞Mn = −∞, a.s. on sample paths. A sufficient condition on the martingale is a uniform control on the ratio of the L2 and L1 norms of the increments. Near-symmetry of the increments provides an alternative condition. We also discuss a counterexample when these con...
