Diagnosis: Osteitis Condensans of the Clavicle
Full history:
33 year-old woman with three month history of left medial clavicular pain. There was no history of known trauma, fever, arthritis or intravenous drug abuse.
Radiopharmaceutical:
Tc-99m MDP i.v.
Findings:
Moderately increased focal uptake is seen in the medial ends of both clavicles, left greater than right. The computed tomographic examination confirmed sclerosis in the clavicular heads, left greater than right. These findings, coupled with the clinical presentation, are most consistent with osteitis condensans of the clavicles.
Discussion:
Osteitis condensans of the clavicles tends to occur in women with an average age of 40 years. It is characterized clinically by pain and swelling over the medial end of the clavicle. Bony sclerosis and eburnation may occur, but the sternoclavicular joint remains intact. The etiology of this disorder is unclear, but it may represent a response to mechanical stress. Differential diagnostic possibilities include ischemic ncecrosis of the medial clavicular epiphysis, sternocostoclavicular hyperostosis and septic arthritis of the sternoclavicular joint. Clinical information usually helps to distinguish among these possibilities.
