Osteoid osteoma is a benign bone tumor forming mature bone, often causing nocturnal pain. Diagnosis and location are confirmed by CT, with treatment ranging from NSAIDs to surgical options like radiofrequency ablation.
Area of Science:
- Orthopedics
- Oncology
- Radiology
Background:
- Osteoid osteoma is a benign bone-forming tumor, comprising 5% of all bone tumors and 11% of benign ones.
- It predominantly affects the appendicular skeleton, particularly long bones, and is classified as a stage-2 lesion.
- Common symptoms include nocturnal pain responsive to NSAIDs and salicylates.
Purpose of the Study:
- To provide a comprehensive overview of osteoid osteoma.
- To discuss diagnostic modalities and treatment options for osteoid osteoma.
Main Methods:
- Literature review on osteoid osteoma epidemiology, clinical presentation, diagnosis, and management.
- Emphasis on the role of CT in diagnosis and localization.
Main Results:
- Osteoid osteoma is characterized by direct formation of mature bone by tumor cells.
- CT is the primary imaging modality for diagnosis and lesion localization (cortical, subperiosteal, medullary).
- Treatment options include non-operative management (NSAIDs) and surgical interventions such as RF ablation, percutaneous excision, and en bloc resection.
Conclusions:
- Osteoid osteoma is a benign tumor with a characteristic presentation and imaging findings.
- Treatment is guided by symptom severity and response to conservative measures, with minimally invasive options available.
