Summary
A rare psoas muscle tumor was found in a young patient. Pathological analysis revealed it was a benign angiomyolipoma, an uncommon retroperitoneal finding.
Area of Science:
- Oncology
- Pathology
- Radiology
Background:
- Retroperitoneal tumors are rare, especially in young individuals.
- Diagnostic imaging modalities like ultrasound (US), urography, and computed tomography (CT) can be used for initial assessment.
- Preoperative diagnosis of retroperitoneal tumors can be challenging.
Observation:
- A young patient presented with a subclinical retroperitoneal mass.
- Despite extensive diagnostic workup including US, urography, and CT, the tumor's nature remained indeterminate.
- Surgical intervention was deemed necessary due to suspicion of malignancy.
Findings:
- Post-surgical pathological analysis confirmed the retroperitoneal mass as an angiomyolipoma.
- The angiomyolipoma was located within the psoas muscle, an unusual anatomical site for this tumor type.
- This represents a benign tumor in an uncommon location.
Implications:
- This case highlights the diagnostic challenges associated with subclinical retroperitoneal masses.
- Angiomyolipomas, typically found in the kidney, can occur in extrarenal sites like the psoas muscle.
- Reporting such uncommon presentations aids in expanding the understanding of tumor diversity and diagnostic considerations.
