Summary
Inflammatory pseudotumor is a rare bone lesion. This case report details a sacral tumor initially misdiagnosed as fibrosarcoma, highlighting the importance of considering this benign entity.
Area of Science:
- Oncology
- Pathology
- Rheumatology
Background:
- Inflammatory pseudotumor (IP) classification remains debated, with limited reports in bone.
- Distinguishing IP from malignant bone tumors is clinically significant.
Observation:
- A 31-year-old male presented with inflammatory symptoms and a sacral osteolytic lesion.
- Initial imaging and biopsy suggested fibrosarcoma, but surgical resection confirmed IP.
- Symptoms resolved post-surgery, suggesting a paraneoplastic phenomenon.
Findings:
- Technetium scintigraphy indicated sacroiliac joint involvement.
- Non-response to anti-inflammatory and sulfasalazine treatment.
- Histopathological examination post-resection was crucial for definitive diagnosis.
Implications:
- This case expands the known skeletal locations for IP.
- Highlights diagnostic challenges and the potential for paraneoplastic syndromes.
- Emphasizes the need for thorough evaluation to differentiate IP from malignancy.
