Discal cysts are extremely rare pathologies that occur most often in the lumbar region. The clinical symptoms of discal cysts are indistinguishable from those of a lumbar disc herniation. The aetiology and pathogenesis of discal cysts remain unknown. The optimal treatment of discal cysts also remains controversial. Most cases of lumbar discal cysts are treated surgically, while some cases regress spontaneously. In this article, we report a case of a lumbar discal cyst treated surgically by microdiscectomy. We discuss the treatment options for discal cysts in the context of the literature.

A case of isolated brucella disk infection mimicking fragmented disk herniation is presented. MRI studies were performed two times in 6 months, both of which did not show any signs of spondylitis. Since brucella infections are seen along with spondylitis, this case has attracted our attention. We focused on radiological findings in this pure brucella disk infection.

Vertebral Eosinophilic Granuloma (EG) is a frequently reported disease, but further dissemination rarely occurs when the initial lesion is in the lumbar region. We present a case of EG, initially located in L5 vertebra, which disseminated to the skeletal bones and pulmonary system months after total excision in an adult.

In this study, there was a prolongation of T2 indicating regeneration in the nucleus pulposus after laser therapy and these results were found to be consistent with VAS measurements after a long-term follow-up. This study, which demonstrates the quantitative efficacy of laser therapy, indicates that MRG can be more effectively used in the future.
