Facetal cysts are usually encountered as incidental radiological findings in spinal imaging studies. Only rarely can neurological symptoms be attributed to them. These cysts are lined by vascularized synovial tissue. There are few reports in literature of hemorrhagic transformation in these cysts with sudden increase in size precipitating symptoms acutely. We report one such case where the existence of a hitherto undiagnosed cyst was unmasked by the haemorrhage. There is a need to be aware of this complication in patients with untreated or incidentally diagnosed cysts so that any sudden neurological deterioration can be dealt with promptly.
小关节囊肿通常是在脊柱影像学检查中偶然发现的。只有极少数情况下，神经症状可归因于这些囊肿。这些囊肿内衬有血管化的滑膜组织。文献中很少有关于这些囊肿发生出血性转变且囊肿大小突然增加并急性引发症状的报道。我们报告了这样一例病例，其中一个此前未被诊断出的囊肿因出血而被发现。对于未治疗或偶然诊断出囊肿的患者，有必要意识到这种并发症，以便能及时处理任何突然出现的神经功能恶化情况。
