Osteoid Osteoma with Double Nidus

Abstract

This study reports the case of a 22-year-old male patient with dull pain below his right knee with osteoid osteoma, who was operated and his pains passed away. The pain increased at nights and was relieved by aspirin or nonsteroid antiinflammatory drugs. No abnormal finding was noted during his physical examination and on his laboratory blood tests. Interestingly, this osteoid osteoma case presents double nidus. It is important to share this finding, as only few osteoid osteoma cases with double nidus have been reported in the literature (2,3).
