Abstract:
The MR findings of two patients with bleeding renal arteriovenous fistulae are presented. In each case MR demonstrated a perinephric hemorrhage in association with the distinctive finding of a discrete focal intraparenchymal hematoma.
Insights
Magnetic resonance imaging (MRI) revealed perinephric hemorrhage in two patients with bleeding renal arteriovenous fistulae. The distinctive finding was a focal intraparenchymal hematoma associated with the bleeding.
Area of Science:
- Radiology
- Medical Imaging
- Nephrology
Background:
- Renal arteriovenous fistulae (AVF) can present with significant complications, including hemorrhage.
- Accurate imaging is crucial for diagnosing and managing renal AVF.
Observation:
- This study presents the magnetic resonance (MR) findings in two patients with bleeding renal AVF.
- Both patients exhibited perinephric hemorrhage.
- A key observation was the presence of a discrete focal intraparenchymal hematoma.
Findings:
- MR imaging effectively identified perinephric hemorrhage in patients with bleeding renal AVF.
- The distinct finding of a focal intraparenchymal hematoma was consistently observed in conjunction with the hemorrhage.
- These findings highlight specific MR characteristics associated with complicated renal AVF.
Implications:
- MR imaging is a valuable tool for detecting hemorrhage and associated intraparenchymal hematomas in renal AVF.
- Understanding these MR findings can aid in the diagnosis and management of bleeding renal AVF.
- This imaging pattern may help differentiate bleeding AVF from other renal pathologies.
