Intradural dermoid cysts may rupture and subsequent subarachnoid dissemination of lipid droplets has been described before. However, the rupture of a spinal dermoid cyst into the central spinal canal is a rare entity. In this context, dissemination of fat into the intracranial subarachnoid space with local progression is a peculiar finding that, to the best of our knowledge, has not been published so far. We describe the case of a 28-year-old man with a dermoid cyst at the upper lumbar level as part of a complex congenital craniospinal malformation, presenting with new unspecific neurologic symptoms. CT and MRI revealed disseminated intraventricular and subarachnoid lipid droplets intracranially and in the spine not present on previous CT and MRI scans obtained eight years earlier. Thus, repeated rupture of a spinal dermoid cyst with subarachnoid spread and/or secondary proliferation should be suspected.
硬脊膜内皮样囊肿可能会破裂，之前已有关于脂质小滴随后在蛛网膜下腔播散的描述。然而，脊髓皮样囊肿破裂进入中央椎管是一种罕见的情况。在这种情况下，脂肪播散至颅内蛛网膜下腔并伴有局部进展是一种特殊的发现，据我们所知，迄今为止尚未见相关报道。我们描述了一名28岁男性病例，其腰上段存在一个皮样囊肿，是复杂先天性颅脊柱畸形的一部分，出现了新的非特异性神经症状。CT和MRI显示颅内和脊柱内存在脑室和蛛网膜下腔播散的脂质小滴，而八年前的CT和MRI扫描未显示这些情况。因此，应怀疑脊髓皮样囊肿反复破裂伴蛛网膜下腔播散和/或继发性增殖。
