Osteoid Osteoma of the Triquetrum Bone in a Child: A Rare and Often Misdiagnosed Cause of Chronic Wrist Pain

Key Points

To explore a case of osteoid osteoma in a child presenting with chronic wrist pain and highlight the diagnostic process.
An 11-year-old girl presented with left wrist pain and underwent MRI and CT imaging.
MRI showed nonspecific bone marrow edema; CT identified a small nidus in the triquetrum.
Surgical excision was performed to confirm the diagnosis and treat symptoms.
Imaging indicated osteoid osteoma of the triquetrum, which was confirmed via surgical excision.
The patient experienced complete symptom resolution post-surgery.
Diagnosis via CT was crucial for identifying the underlying condition.

Abstract

An 11-year-old girl presented with 9 months of left wrist pain, worse at night and partially responsive to NSAIDs. Imaging showed nonspecific bone marrow edema on MRI, but CT revealed a small nidus in the triquetrum. Surgical excision confirmed osteoid osteoma, with complete symptom resolution. Osteoid osteoma of the triquetrum, though rare, should be considered in children with chronic wrist pain. CT is essential for diagnosis, and surgical excision leads to excellent outcomes.
