Extrarenal retroperitoneal angiomyolipoma with unusual evolution

Area of Science:

• Urology
• Surgical Oncology
• Radiology

Background:

• Angiomyolipomas are benign tumors typically found in the kidney.
• Extrarenal angiomyolipomas are rare, with retroperitoneal location being even less common.
• Unusual tumor evolution and presentation can pose diagnostic and therapeutic challenges.

Observation:

• A patient presented with an extrarenal retroperitoneal angiomyolipoma.
• The tumor exhibited unusual behavior by herniating through the inguinal canal, creating an extraperitoneal hernia.
• Associated findings included ureteral duplicity and hydronephrosis, adding complexity to the case.

Findings:

• Surgical intervention involved en bloc removal of the tumor and the right kidney.
• The patient experienced a favorable postoperative recovery.
• Long-term follow-up demonstrated no recurrence of the tumor seven years after surgery.

Implications:

• This case highlights the importance of considering rare presentations of common tumors.
• Early and accurate diagnosis is crucial for effective management of complex retroperitoneal masses.
• Successful surgical management can lead to long-term positive outcomes even in challenging cases.
