A case of Erdheim-Chester disease initially mistaken for retroperitoneal lymphoma.

Radiol Case Rep 2020 May 18;15(5):570-575. Epub 2020 Mar 18.

Radiologist Consultant, College of Medicine, Qassim University, Saudi Arabia.

Erdheim-Chester disease (ECD) is an infrequent, autoimmune disorder that is not Langerhans histiocytosis and is characterized by bilateral sclerosis of the diametaphyseal medullary regions of the long bones and possible multiorgan involvement. A mononuclear foam histiocyte infiltrate determines the condition's histopathologic form and extensive fibrosis. A case of ECD in a 52-year-old man with retroperitoneal infiltration and bone involvement is described here, in whom the diagnosis was established only after a 3-year course of multiple nonspecific symptoms.

A Rare Cause of Persistent Blood Loss after Continuous Ambulatory Peritoneal Dialysis Catheter Placement.

Case Rep Surg 2020 20;2020:1309418. Epub 2020 Feb 20.

Department of Surgery, Treant Health Care Group, Scheper Hospital, Boermarkeweg 60, 7824 AA Emmen, Netherlands.

The laparoscopic placement of a continuous ambulatory peritoneal dialysis (CAPD) catheter is a widely used method in patients with end stage renal disease (ESRD). The potential complications of this procedure include perforation of intra-abdominal organs, surgical site infection, peritonitis, catheter migration, catheter blockage, port site herniation, and bleeding. In most cases, bleeding is considered to be an early-onset complication because it mostly occurs within the first seven days after surgery. Read More

Ureterolysis with ureterotomy and omental sleeve wrap in patients with radiation induced pelvic retroperitoneal fibrosis.

Cent European J Urol 2019 16;72(3):307-311. Epub 2019 Sep 16.

University of Florida, Department of Urology, USA.

Introduction: Secondary retroperitoneal fibrosis (RPF) due to pelvic radiation alone or together with pelvic surgery is one of the causes of obstructive renal failure. Ureteral obstruction is caused by ischemic stricture and encasement by fibrotic tissue. Endo-ureterotomy alone, without vascular supply, is not successful in these cases. Read More

Left-sided portal hypertension due to retroperitoneal fibrosis treated with an oesophagus preserving, modified Sugiura procedure.

Ann R Coll Surg Engl 2020 Feb 29;102(2):e48-e50. Epub 2019 Oct 29.

La Princesa University Hospital, Madrid, Spain.

Left-sided portal hypertension is a very uncommon condition and retroperitoneal fibrosis has rarely been reported as a cause. We present the case of a 77-year-old man with retroperitoneal fibrosis obstructing the splenic vein and causing recurrent episodes of upper gastrointestinal bleeding. Computed tomography showed a retroperitoneal mass as being responsible for the obstruction of the splenic vein, splenomegaly, and diffuse varices around the gastrosplenic and gastrohepatic ligaments.

Traumatic pancreatitis.

Abdom Radiol (NY) 2020 May;45(5):1265-1276

Department of Radiology, University of Alabama at Birmingham, 619 19th Street South, JTN 456, Birmingham, AL, 35294, USA.

Post-traumatic pancreatitis can develop secondary to blunt or penetrating abdominal trauma, post-endoscopic retrograde cholangiopancreatography, or following pancreatic surgery. Clinical findings are often nonspecific, and imaging findings can be subtle on presentation. Early diagnosis of pancreatic duct injury is critical and informs management strategy; imaging plays important role in diagnosis of ductal injury and identification of delayed complications such as retroperitoneal fluid collections, pancreatic fistula, ductal strictures, and recurrent pancreatitis.
