Dermoid cysts represent a rare group of tumors manifesting predominantly in adulthood. Rupture of these tumors is well described with it being symptomatic more commonly intracranially as compared to central canal rupture of intraspinally located dermoid tumor which not only is uncommon, but also frequently asymptomatic. The authors report an unusual case of asymptomatic conus dermoid in a young male diagnosed when investigated for a symptomatic isolated central canal rupture. Fatty contents within the central canal may be a harbinger of an underlying dermoid tumor and a whole spine MRI should be performed in such cases to rule out this bizarre presentation.
皮样囊肿是一组罕见的肿瘤，主要在成年期出现。这些肿瘤的破裂已有充分描述，与脊髓内皮样肿瘤的中央管破裂相比，其症状更常见于颅内，脊髓内皮样肿瘤的中央管破裂不仅不常见，而且常常无症状。作者报告了一例年轻男性无症状圆锥皮样囊肿的罕见病例，该病例是在对有症状的孤立性中央管破裂进行检查时被诊断出来的。中央管内的脂肪成分可能是潜在皮样肿瘤的先兆，在这种情况下应进行全脊柱磁共振成像以排除这种奇特的表现。
