Summary
A rare double-nidus osteoid osteoma in the index finger was diagnosed after initial misdiagnosis. Surgical removal of both nidi led to complete symptom resolution, confirming this rare presentation of osteoid osteoma.
Area of Science:
- Orthopedic Surgery
- Oncology
- Radiology
Background:
- Osteoid osteoma is a benign bone tumor typically presenting with a single nidus.
- Diagnosis can be challenging, especially in small bones like those in the hand.
- Recurrent or persistent symptoms after initial treatment may indicate an incomplete diagnosis.
Observation:
- A patient presented with persistent finger pain, initially diagnosed as osteoid osteoma.
- Histological confirmation was obtained postoperatively, but symptoms recurred.
- Radiographic re-evaluation revealed a second, previously undetected nidus.
Findings:
- The definitive diagnosis was a double-nidus osteoid osteoma.
- Surgical en bloc resection of the second nidus was performed.
- Histological examination confirmed the second nidus as osteoid osteoma.
Implications:
- This case highlights the importance of thorough radiographic analysis for diagnosing complex bone tumors.
- Double-nidus osteoid osteoma is a rare entity that can lead to diagnostic challenges and treatment failures.
- Complete surgical resection of all nidi is crucial for successful management of osteoid osteoma.
