Summary
A rare abdominal hemangiopericytoma, a soft tissue tumor, was identified. This tumor mimicked an accessory spleen on imaging studies, highlighting diagnostic challenges.
Area of Science:
- Oncology
- Radiology
- Pathology
Background:
- Hemangiopericytoma is a soft tissue tumor originating from pericytes.
- These neoplasms can occur in various body locations, including soft tissue and bone.
Observation:
- A case of abdominal hemangiopericytoma is presented.
- The tumor was histologically confirmed.
Findings:
- The abdominal hemangiopericytoma mimicked an accessory spleen.
- Diagnostic imaging, including Tc-99m sulfur colloid scans, contributed to this misinterpretation.
Implications:
- This case underscores the importance of considering rare soft tissue tumors in abdominal imaging differential diagnoses.
- Accurate histological examination is crucial for definitive diagnosis of hemangiopericytoma.
