A 67-year-old female presented with complains slowly progressing bilateral leg weakness with associated chronic low back pain. There was no bowel or bladder involvement. On examination, motor and sensory exams were normal. Lab work was unremarkable. Magnetic resonance imaging (MRI) was performed which demonstrated anterior displacement of the spinal cord with an associated kink at T6 level with cerebrospinal fluid (CSF) pulsation artifacts in the posterior subarachnoid space []. High-resolution thin slice T2-weighted imaging demonstrated subtle small focus of herniated cord through the dural defect []. The findings favored spinal cord herniation instead of a posterior arachnoid cyst. To confirm the findings, a CT myelogram was performed which showed anterior cord kink at T6 with complete opacification of CSF posterior to the kinked and anteriorly displaced spinal cord confirming spinal cord herniation and excluding arachnoid cyst [].
A 52-year-old female presented with progressive onset lower extremity weakness and gait abnormalities. Neurological exam was within normal limits. Lab parameters were unremarkable. She denied a history of trauma. MRI thoracic spine demonstrated acute ventral kink in the thoracic spinal cord at T4-5 level [].
