Summary
Epithelioid angiomyolipoma, a rare kidney tumor variant, can be malignant. This report details imaging findings in two diverse patient cases, highlighting its potential for aggressive growth.
Area of Science:
- Nephrology
- Oncology
- Radiology
Background:
- Epithelioid angiomyolipoma is a rare renal tumor variant.
- It can occur with or without tuberous sclerosis complex.
- Potential for malignancy exists.
Observation:
- Two cases of epithelioid angiomyolipoma are presented.
- Case 1: Tuberous sclerosis complex patient with tumor in horseshoe kidney extending into inferior vena cava and right atrium.
- Case 2: 62-year-old hypertensive male with epithelioid angiomyolipoma.
Findings:
- Imaging findings of epithelioid angiomyolipoma are described.
- Demonstrates potential for extensive vascular invasion.
- Highlights varied clinical presentations.
Implications:
- Early and accurate diagnosis is crucial for patient management.
- Understanding imaging characteristics aids in surgical planning.
- Further research into epithelioid angiomyolipoma behavior is warranted.
