Flank Pain: Imaging Findings Doctors May Look For

Flank pain can reflect kidney, ureter, musculoskeletal, or referred abdominal causes. Imaging is used when stone disease, obstruction, infection, or another structural issue is suspected.

Educational overview only. Imaging findings, clinician review, and the full clinical picture matter more than a symptom page alone.

Analyze My Report

Educational only. RadDx helps explain report wording and does not replace clinician guidance.

Works with CT, MRI, ultrasound, and X-ray reports.

Possible causes doctors may consider

  • Kidney cyst or renal finding

    Many renal findings are incidental, but some may be discovered during a flank pain workup.

  • Renal mass

    A renal mass is usually not the most common explanation for flank pain, but it is an imaging finding doctors would evaluate carefully.

  • Spine-related referred pain

    Lower thoracic or lumbar spine issues can sometimes overlap with flank discomfort.

When imaging may be ordered

  • When there is concern for kidney stone, obstruction, or infection
  • When symptoms persist or recur
  • When clinicians need to distinguish renal from musculoskeletal causes
