Abstract:
Objective To investigate the imaging signs of osteoid osteoma(OO)of short tubular bone.Methods A retrospective analysis was conducted on clinical and imaging data from 19 cases pathologically confirmed of OO in short tubular bones,and a com-parision was made with the imaging findings of 67 cases of long tubular bones.Results Among the 19 cases of OO in short tubular bones,73.70%of cases were under 30 years old.There were 16 cases involved the hand's short tubular bones,with 14 cases in the phalanges(1 in the thumb,4 in the index finger,5 in the middle finger,2 in the ring finger,2 in the little finger)and 2 cases in the metacarpals.Three cases involved the short tubular bones of the foot,all in the metatarsals.Five cases reported increased pain at night,three cases experienced relief with nonsteroidal anti-inflammatory drugs,and two cases did not take any medication.All lesions were osteolytic,with mineralisation within the nidus and varying degrees of surrounding bone sclerosis,bone marrow edema,and soft tissue edema.Compared to OO in long tubular bones,OO in short tubular bones more frequently exhibited expansile and discontinu-ous cortical bone features,but the degree and extent of bone sclerosis were less pronounced.Conclusion Short tubular bones are a rare location for OO,often lacking typical clinical symptoms,which can easily lead to misdiagnosis.Therefore,close attention should be paid to its imaging characteristics.
