Intraosseous ganglia are occasionally found affecting the carpal bones of the hand and should be considered in the differential diagnosis of chronic wrist pain. They have characteristic radiographic findings of a cyst with a thin sclerotic rim. This case report illustrates an unusual presentation of a cyst in the lunate with successful treatment. Standard of care includes curettage and bone grafting with minimal recurrence reported.
