摘　　要：骨斑点症属硬化性骨发育异常，临床上极罕见，本文报告16例（男10例，女6例），X线表现具有特征性，通常为多数边缘清楚、密度均匀、成串的、小的圆形或椭圆形致密斑点，对称分布于关节端的松质骨内，最好发于长管骨的骨骺和干骺区，腕、跗骨、骨盆和肩胛骨，肋、销骨和脊柱罕见，CT扫描能明确显示斑点所在骨内的部位，病灶大多位于松质骨内，并与骨小梁的分布一致，少数可位于骨皮质内，或紧贴骨皮质的内或外表面，在儿童期，随访片显示病灶大小和多少，可增加或减少以至消失，对其发病机理、合并症和鉴别诊断等进行了讨论。Osteopoikilosis is an asymptomatic osteosclerotic dysplasia that is extremely rare clinically. 16 cases (10 male, 6 female) of this disorder were analysed in this paper. X-ray findings are diagnostic. Numerous small, well -defined, homogeneous circular or ovoid foci of increased radiodensity are clustered in periarticular osseous regions. A symmetric distribution is observed, with a predilection for the epiphyses and metaphyses of long tubular bones, carpus, tarsus, pelvis and scapulae; involvement of the ribs, clavicles and spine is rare. CT scan distinctly reveals the locations in bone of the patches which are seen mostly within the spongiosa, the distribution of the lisions is identical to the direction of the bone trabecula. The foci may be rarely located within the cortical bone or in contact with the surface of the inner or the outer cortex. On serial radiographs, the radiopaque areas can increase or decrease in size and number or disappear in childhood. The complications and differential diagnosis were also discussed.
