This study describes the radiographic, CT, and MR imaging features of surface osteomas of the appendicular skeleton in four patients without Gardner's syndrome or tuberous sclerosis and reviews the incidence and management options of this uncommon tumor.
On imaging (best seen on CT), the osteomas were homogeneously dense-as dense at the periphery as the base-and without an accompanying soft-tissue mass, cortical destruction, or intramedullary invasion. The margins of each osteoma were smooth or smoothly lobulated. When the correct diagnosis was considered in two patients, close clinical follow-up or marginal excision were the management options chosen. Histologic examination of the tumors revealed dense sclerotic lamellar bone with haversian systems that showed features similar to those of normal cortical bone. During a follow-up period of 6 months to 5 years, patients have had no local recurrences or metastases.
本研究描述了4例无加德纳综合征或结节性硬化症的四肢骨骼表面骨瘤的X线、CT和MR成像特征，并回顾了这种罕见肿瘤的发病率及治疗选择。
在影像学检查中（CT显示最佳），骨瘤密度均匀，周边与基底部密度相同，无软组织肿块、皮质破坏或髓内侵犯。每个骨瘤的边缘光滑或呈光滑分叶状。当两名患者被考虑正确诊断时，密切的临床随访或边缘切除是选择的治疗方案。肿瘤的组织学检查显示有致密硬化的板层骨和哈弗斯系统，其特征与正常皮质骨相似。在6个月至5年的随访期内，患者无局部复发或转移。
