Klinik für Rheumatologie, Universitätsspital Zürich.

Chronic Periaortitis The term chronic periaortitis encompasses several fibroinflammatory diseases that manifest on or around the abdominal aorta which may be associated with aneurysm formation. Formerly distinct entities are grouped together, such as idiopathic retroperitoneal fibrosis (Ormond's disease), inflammatory aortic aneurysm, and perianeurysmal retroperitoneal fibrosis. They may also occur IgG4-related. Read More

Thinking Beyond Acute Kidney Injury.

Case Rep Nephrol Dial 2022 Jan-Apr;12(1):16-21. Epub 2022 Mar 10.

Division of Nephrology, Department of Medicine, University of South Alabama, Mobile, Alabama, USA.

Acute kidney injury (AKI) can be a significant clue to solving a puzzling patient presentation. Postrenal AKI should be suspected if imaging shows any degree of hydronephrosis and can be caused by a variety of conditions. Diagnosis of urinary obstruction without significant dilatation of the pelvic-ureteral system requires a higher degree of suspicion, and hence, its identification can become late. Read More

Spontaneous ureteric rupture due to high pressure chronic retention.

JRSM Open 2022 Mar 9;13(3):20542704221077556. Epub 2022 Mar 9.

Department of Urology, Princess Royal University Hospital, King's College Hospital NHS Foundation Trust, Farnborough Common, Orpington BR6 8ND, UK.

Spontaneous ureteric rupture is a rare phenomenon which can be traumatic or non-traumatic that may arise from ureteric obstruction, trauma, mucosal inflammation from urolithiasis, connective tissue disease or retroperitoneal fibrosis. High pressure chronic retention is characterised by noctural enuresis, a tense palpable bladder, hypertension, progressive renal impairment, bilateral hydronephrosis and hydroureter on imaging. Obstructive urological symptoms are typically absent in uncomplicated cases. Read More

Performance characteristics of F-fluciclovine positron emission tomography/computed tomography prior to retroperitoneal lymph node dissection.

Can Urol Assoc J 2022 Mar;16(3):E167-E172

Department of Urology, UT Southwestern Medical Center, Dallas, TX, United States.

Introduction: We aimed to determine whether anti-1-amino-3-F-fluorocyclobutane-1-carboxylic acid (F-fluciclovine) positron emission tomography/computed tomography (PET/CT) can accurately detect residual non-seminomatous germ cell tumor (NSGCT) prior to retroperitoneal lymph node dissection (RPLND). There is no reliable way to differentiate between fibrosis/necrosis, teratoma, and viable germ cell tumor in patients receiving post-chemotherapy RPLND. Functional imaging, including F-fludeoxyglucose (18F-FDG) PET/CT, has been disappointing. Read More

Imatinib-induced retroperitoneal fibrosis in a child with chronic myeloid leukemia: a case report.

Am J Blood Res 2021 15;11(6):600-604. Epub 2021 Dec 15.

Tata Memorial Centre, Homi Bhaba National Instituite Mumbai, India.

A 12 year old boy with chronic myeloid leukemia (CML) presenting with bilateral pitting pedal edema and abdominal distension after about 41 months of imatinib therapy and was diagnosed to have retroperitoneal fibrosis (RPF) based on imaging and biopsy findings. He was found to have bilateral hydroureteronephrosis needing double-J stenting to the more severely affected right ureter. Imatinib was briefly interrupted and restarted later due to rising transcript levels and unavailability of other alternatives at that time which was later substituted by dasatinib once generic versions became available.

Department of Internal Medicine/Dutch National Center of Expertise Retroperitoneal Fibrosis, Albert Schweitzer Hospital, PO Box 444, 3300 AK, Dordrecht, The Netherlands.

Although much debated, an exaggerated inflammatory response to advanced atherosclerosis has been implicated in the pathogenesis of idiopathic retroperitoneal fibrosis (RPF). Clinical presentation, infrarenal abdominal aortic diameter and RPF mass thickness were retrospectively analyzed in 166 patients with idiopathic RPF seen at our referral center between April 1998 and December 2019. Patients were stratified to their infrarenal abdominal aortic diameter at presentation (i. Read More

Clin Exp Rheumatol 2021 11 11. Epub 2021 Nov 11.

Academy of Athens, Greece.

Objectives: Retroperitoneal fibrosis (RPF) is mostly idiopathic (iRPF); however, it can be secondary to drugs, malignancies, infections, or, as recently recognised, can be part of the IgG4-related diseases. The aim of our study was i) to describe the presenting clinical/laboratory/imaging features and treatment modalities used in patients with iRPF and ii) to evaluate factors potentially associated with disease relapse.

Methods: The medical records of patients diagnosed with iRPF and followed in four tertiary medical units in Athens, Greece from 2000 to 2018 were retrospectively evaluated. Read More

The Use of Systematic Clinical Approach in Diagnosing Rare Cases of Secondary Hypertension: A Case Report of Mid Aortic Syndrome in a Young Patient.

Cureus 2021 Nov 2;13(11):e19215. Epub 2021 Nov 2.

Trauma and Surgical Critical Care, University of Florida College of Medicine, Gainesville, USA.

Mid aortic syndrome (MAS) is a rare disease that occurs in children and young adults. The most important clinical feature reflecting vascular involvement is the presence of systemic hypertension. The diagnosis is usually made during the imaging assessment of secondary hypertension when routine echocardiography fails to identify the characteristic morphological or Doppler flow patterns associated with thoracic arch coarctation in the presence of the clinical features of aortic vascular obstruction.

Aortitis is an inflammatory phenomenon involving one or more layers of the aorta and can have infectious or noninfectious etiologies. Complications of aortitis include aneurysm, dissection, and rupture, which can lead to ischemic organs and ultimately death. Noninfectious aortitis is often secondary to trauma or results from a systemic inflammatory process.

Renal Involvement in Retroperitoneal Fibrosis: Prevalence, Impact and Management Challenges.

Int J Nephrol Renovasc Dis 2021 29;14:279-289. Epub 2021 Jul 29.

Department of Rheumatology, Kanazawa University Hospital, Kanazawa, Japan.

Retroperitoneal fibrosis (RPF) is a rare disorder consisting of idiopathic and various secondary forms and characterized by chronic inflammatory infiltrates and marked fibrosis in the retroperitoneal space. In idiopathic RPF (IRPF), 35-60% of cases have been reported to be IgG4-related RPF, the retroperitoneal lesions of IgG4-related disease (IgG4-RD). IRPF can frequently lead to renal insufficiency mediated by urinary tract obstruction and hydronephrosis irrespective of being IgG4-related or not. Read More

State of the art of F-FDG PET/CT application in inflammation and infection: a guide for image acquisition and interpretation.

Clin Transl Imaging 2021 10;9(4):299-339. Epub 2021 Jul 10.

Regional Center of Nuclear Medicine, Department of Translational Research and Advanced Technologies in Medicine, University of Pisa, Pisa, Italy.

Aim: The diagnosis, severity and extent of a sterile inflammation or a septic infection could be challenging since there is not one single test able to achieve an accurate diagnosis. The clinical use of 18F-fluorodeoxyglucose ([F]FDG) positron emission tomography/computed tomography (PET/CT) imaging in the assessment of inflammation and infection is increasing worldwide. The purpose of this paper is to achieve an Italian consensus document on [F]FDG PET/CT or PET/MRI in inflammatory and infectious diseases, such as osteomyelitis (OM), prosthetic joint infections (PJI), infective endocarditis (IE), prosthetic valve endocarditis (PVE), cardiac implantable electronic device infections (CIEDI), systemic and cardiac sarcoidosis (SS/CS), diabetic foot (DF), fungal infections (FI), tuberculosis (TBC), fever and inflammation of unknown origin (FUO/IUO), pediatric infections (PI), inflammatory bowel diseases (IBD), spine infections (SI), vascular graft infections (VGI), large vessel vasculitis (LVV), retroperitoneal fibrosis (RF) and COVID-19 infections.
