Abstract:
Peri-aortitis retroperitoneal fibrosis is characterized by a reaction of a variable inflammatory nature while constricting the organs crossing the retroperitoneal space, notably the ureters and the blood vessels. It is difficult to diagnose such a rare disease. We bring about here six cases of periaortic retroperitoneal fibrosis diagnosed from systemic, digestive, urinary or vascular signs. Early diagnosis is often difficult and is shown to be established after an average of three months investigation. The average age of these patients, all of the male sex, is 58 years old (54 to 90). In the six cases this disease appears to be idiopathic even though in two cases it is associated to giant temporal arteritis and polymyalgia rheumatica. TDM remains the best diagnostic tool to point out the existence of this fibrosis, to observe its evolution and to investigate for any extension of the disease. The etiology of this fibrosis remains a mysterious one; however an immunologic origin has been suggested. Medical treatment by corticosteroids is often successful but the long term evolution of the disease is still uncertain.
Insights
Peri-aortitis retroperitoneal fibrosis, a rare inflammatory condition, constricts vital organs. Diagnosis is challenging, often requiring extensive investigation, but CT scans are key for identification and monitoring.
Area of Science:
- Retroperitoneal diseases
- Inflammatory disorders
- Vascular and urologic complications
Background:
- Peri-aortitis retroperitoneal fibrosis is a rare inflammatory condition.
- It constricts retroperitoneal organs, including ureters and blood vessels.
- Diagnosis is often delayed due to its rarity and varied presentation.
Observation:
- Six cases of peri-aortitis retroperitoneal fibrosis are presented.
- Patients were predominantly male, with an average age of 58.
- Idiopathic cases were common, with two associated with giant temporal arteritis and polymyalgia rheumatica.
Findings:
- Computed tomography (CT) is the primary diagnostic tool.
- CT aids in identifying fibrosis, monitoring progression, and assessing disease extent.
- Early diagnosis averaged three months of investigation across the cases.
Implications:
- The etiology remains unclear, though an immunologic origin is suspected.
- Corticosteroid treatment shows promise but long-term outcomes are uncertain.
- Further research is needed to elucidate causes and optimize management strategies.
