Summary
Retroperitoneal bleeding caused by renal angiomyolipoma occurred in an anticoagulated patient. Discontinuing anticoagulation successfully stopped the bleeding, highlighting a critical management consideration for this rare tumor.
Area of Science:
- Nephrology
- Oncology
- Radiology
Background:
- Renal angiomyolipoma is a rare benign renal tumor.
- It is often associated with tuberous sclerosis complex.
- Spontaneous bleeding is a rare but serious complication.
Observation:
- An 81-year-old woman on oral anticoagulation presented with flank pain, anemia, and irregular pulse.
- Imaging revealed a medium-sized renal angiomyolipoma causing retroperitoneal bleeding.
- Bilateral renal angiomyolipomas were identified, without evidence of tuberous sclerosis.
Findings:
- Discontinuation of anticoagulant therapy led to cessation of bleeding.
- Renal angiomyolipoma, though benign, can present with life-threatening hemorrhage.
- This case highlights the importance of considering anticoagulation in patients with renal angiomyolipoma.
Implications:
- Management of anticoagulation in patients with renal angiomyolipoma requires careful risk-benefit assessment.
- Prompt diagnosis and cessation of anticoagulation can be life-saving.
- Further research into the management of anticoagulated patients with renal tumors is warranted.
