    Previous history – Bilateral L5 pars defects 7mm spondylolisthesis L5 on S1 amd mild posterior disc bulge result in minor narrowing of the anterior thecal sac.

    Recent severe back pain and a subsequent MRI reading as per below please help me understand what it means
    Sagittal localiser sequences through the cervical spine demonstrate an enlarged midline posterior fossa CSF space, most in keeping with a developmental mega cisterna magna or arachnoid cyst. Segmentation anomaly at the C4/5 level with partial fusion of the posterior vertebral bodies and posterior of the posterior elements bilaterally resulting in cervical malalignment with straightening through this region. Nominal posterior disc osteophyte complexes involving the C2/3 and C4/5 level, without significant central canal or neural compressive foraminal stenosis.

    Your report is confusing. You note a previously diagnosed isthmic spondylolisthesis at L5-S1 with a 7mm slip. You then note a cervical MRI with findings. I assume this is for a new pain unrelated to your lumbar disorder.

    In regards to your cervical spine, you have an enlarged spinal canal and foramen magnum (hole in the skull where the spinal cord exits). This is associated with Klippel Feil syndrome (see website) a congential fusion of C4-5. Klippel Feil syndrome along with the enlarged canal is typically assocated with some genetic anomolies. As long as the cervical spine is stable, this should lead to no significant concerns in the short term.
