Summary
A rare paraganglioma in the organ of Zuckerkandl was diagnosed in a 37-year-old female presenting with abdominal pain. This retroperitoneal tumor highlights the importance of considering extra-adrenal paragangliomas in abdominal mass diagnoses.
Area of Science:
- Endocrinology
- Surgical Oncology
- Diagnostic Imaging
Background:
- Paragangliomas are rare neuroendocrine tumors originating from extra-adrenal chromaffin cells.
- The organ of Zuckerkandl, located near the aortic bifurcation, is an uncommon site for paraganglioma development.
- Early diagnosis and surgical management are crucial for favorable outcomes.
Observation:
- A 37-year-old female presented with a symptomatic periumbilical mass and radiating lumbar pain.
- Abdominal ultrasonography and computed tomography revealed a highly vascularized retroperitoneal mass adjacent to the aorta.
- Surgical exploration identified an 8x10 cm tumor at the aortic bifurcation, involving the inferior mesenteric artery and displacing the left ureter.
Findings:
- Histopathological examination confirmed the retroperitoneal mass as a paraganglioma.
- The tumor's location and vascularity posed surgical challenges.
- Complete surgical resection was achieved.
Implications:
- This case underscores the necessity of including extra-adrenal paragangliomas in the differential diagnosis of retroperitoneal masses.
- Awareness of paraganglioma presentation near the abdominal aorta aids in timely diagnosis and treatment.
- Further research into the specific characteristics and management of organ of Zuckerkandl paragangliomas is warranted.
