Summary
Ultrasound (US) diagnosis of renal vein thrombosis (RVT) is unclear. A specific US pattern of hyperechoic streaks in interlobular spaces may aid in diagnosing RVT in neonates and in utero.
Area of Science:
- Medical imaging
- Radiology
- Pediatric diagnostics
Background:
- Renal vein thrombosis (RVT) diagnosis using ultrasound (US) lacks specific indicators.
- Classical US features for RVT often present with low specificity.
Observation:
- Three cases of RVT demonstrated a consistent ultrasound pattern.
- This pattern involves hyperechoic streaks within the interlobular spaces of the kidney.
Findings:
- The observed hyperechoic streaks pattern in RVT has been previously reported.
- This specific ultrasound finding was noted in both neonatal and in utero cases.
- Two out of three cases also showed associated vena cava thrombosis.
Implications:
- The hyperechoic streaks pattern may serve as a specific diagnostic sign for renal vein thrombosis.
- This finding could improve the accuracy of US in diagnosing RVT, especially in pediatric populations.
- Further research is warranted to validate this sign's specificity and sensitivity in diverse clinical settings.
