Pseudotumoral ureteral kinking: a computed tomography pitfall.
The Journal of Computed Tomography
|July 1, 1984
Summary
Kinking of a large ureter on computed tomography can mimic a ureteral tumor. This imaging pitfall is likely caused by intraluminal ureteral wall folds.
Area of Science:
- Radiology
- Urology
- Medical Imaging
Background:
- Computed tomography (CT) is a key imaging modality in urological diagnosis.
- Accurate interpretation of CT scans is crucial for patient management.
- Distinguishing benign findings from malignant tumors is a common challenge.
Observation:
- Large ureters exhibiting kinking on CT scans were observed.
- These findings presented a potential diagnostic challenge.
Findings:
- The kinking of a large ureter can create an appearance suggestive of a ureteral tumor on CT.
- This false positive finding is attributed to the intraluminal protrusion of ureteral wall folds.
Implications:
- Radiologists and urologists should be aware of this CT imaging pitfall.
- Understanding this phenomenon can prevent misdiagnosis of ureteral tumors.
- This knowledge aids in accurate CT interpretation for ureteral abnormalities.
