A case of osteoid osteoma in the distal radius epiphysis with atypical onset

Osteoid osteoma of the wrist: Recent advances

Osteoid osteoma is a benign bone tumor usually arising in the diaphysis and metaphysis of the long bones, with male predominance (sex ratio, 2:1). Despite being the most common bone tumor in the wrist, it is still an atypical location for this lesion. The usual presentation is pain that is exacerbated at night and relieved by aspirin or non-steroidal anti-inflammatory drugs. This presentation is not always the case in the wrist, which leads to numerous differential diagnoses and often a delay in definitive diagnosis and treatment. Various imaging modalities can confirm the presence of the tumor and guide the surgical approach. Resection is the gold-standard, with radiofrequency gaining popularity in recent years.

Epiphyseal intramedullary osteoid osteoma in the distal radius: A case report and literature review

Osteoid osteoma is one of the osteoblastic benign bone tumors, which occurs frequently at the cortex of long bones, usually in the diaphysis or metadiaphysis. Although the tumor location in the bone varies, epiphyseal intramedullary osteoid osteoma has been rarely reported. Herein, we report a 14-year-old male patient with epiphyseal intramedullary osteoid osteoma, occurring at the distal radius, with magnetic resonance imaging findings.
