Abstract:
Objective To investigate the imaging manifestations, clinical features and treatment of primary aggressive osteoblastoma (PAO)of the calcaneus.Methods The clinical data,imaging findings and treatment of PAO of the calcaneus in a young man retrospectively analyzed with literature review.The lesion was confirmed by pathology one and half years ago,and recurred after operation 10 months follow-up.Results X-ray and CT revealed expansive destruction of right calcaneus with little calcification or ossification,the bone destruction in the medial part of the calcaneus was obvious,the bone cortex was thin and incontinuous,there was no soft tissue mass or periosteal reaction.The talocalcaneal joint was not involved by the tumor.Neither other bones nor the root of Achilles' tendon showed direct tumor invasion or metastasis but neighboring swelling existed.Conclusion There are no significant differences about imaging manifestations, clinical features and laboratory analyses between primary aggressive and benign osteoblastoma of the calcaneus.The accurate diagnosis of PAO is only depending on pathology.The therapeutic effect with pure curettage and bone grafting for the lesion is not fine and tends to recur and malignant change.
