A 24-year-old man with hereditary multiple exostoses had numbness of the lower extremities and difficulty walking. CT displayed a calcified extradural mass lesion within the spinal canal at T-8 causing cord compression. MR imaging showed it to be contiguous with the upper endplate of T-8, suggesting the diagnosis of osteochondroma, a rare cause of cord compression, and distinguishing the lesion from a calcified disk fragment.
一名患有遗传性多发性骨软骨瘤的24岁男性出现下肢麻木和行走困难。CT显示T8椎管内有一个钙化的硬膜外肿块病变,导致脊髓受压。磁共振成像显示其与T8椎体上终板相连,提示诊断为骨软骨瘤,这是一种导致脊髓受压的罕见原因,并将该病变与钙化的椎间盘碎片区分开来。
