Painless Osteoid Osteoma of Scaphoid Bone: An Incidental Finding

An osteoid osteoma is a small non-malignant osteoblastic tumour with characteristic radiological finding of central lucent nidus with surrounding sclerosis typically presenting as non-traumatic night pain relieved by taking Non-Steroidal Anti-Inflammatory Drugs (NSAIDs). Atypical cases without the cardinal symptoms and different radiological findings can pose diagnostic challenges and result in delayed treatment. Here, we report a rare case of painless osteoid osteoma as an incidental finding in a 60-year-old male presenting for Magnetic Resonance Imaging (MRI) for evaluation of suspected lesion on x-ray, emphasising the importance of considering this rare variant. Since the lesion was too small and asymptomatic, the biopsy was not done and the diagnosis was made on the characteristics findings on x-ray, CT, and MRI.
