    Computed tomography (CT) effectively evaluates retroperitoneal fibrosis, identifying masses and fibrous sheets. While CT is valuable, it may miss limited pelvic fibrosis, but remains useful even in uremic patients.

    Area of Science:

    • Radiology
    • Medical Imaging
    • Surgical Pathology

    Background:

    • Retroperitoneal fibrosis (RPF) is a rare condition characterized by inflammatory and fibrotic processes in the retroperitoneum.
    • Accurate diagnosis and staging of RPF are crucial for effective management and treatment planning.
    • Computed tomography (CT) is a primary imaging modality for evaluating retroperitoneal abnormalities.

    Purpose of the Study:

    • To assess the diagnostic value of CT in surgically proven cases of retroperitoneal fibrosis.
    • To correlate CT findings with surgical observations in patients with RPF.
    • To identify limitations of CT in visualizing retroperitoneal fibrosis.

    Main Methods:

    • Retrospective analysis of 23 surgically confirmed cases of retroperitoneal fibrosis.

  • Evaluation of CT scans performed preoperatively (11 cases) and retrospectively (12 cases).
  • Detailed assessment of the appearance and location of fibrosis on CT, and comparison with surgical findings.

    • Main Results:

    • CT accurately depicted retroperitoneal fibrosis as a prevertebral mass or fibrous sheet in 15 patients, correlating well with surgical findings.
    • CT visualization of fibrosis was limited in 8 cases, primarily when the condition was confined to the pelvis around the distal ureters.
    • Coexisting aortic aneurysm was identified in 5 patients with retroperitoneal fibrosis.

    Conclusions:

    • Computed tomography is a valuable tool for evaluating suspected retroperitoneal fibrosis, providing direct information about the extent and characteristics of the disease.
    • CT findings correlate well with surgical findings in most cases, aiding in diagnosis and surgical planning.
    • CT is a safe and useful imaging modality for patients with retroperitoneal fibrosis, including those who are uremic.
