From: Risk factors for nonresponsive hydration in patients with spinal cerebrospinal fluid leakage
A 22 year-old woman suffered from orthstatic headache after spinal anesthesia. a Axial reconstruction MRM of C-T spine indicates spinal CSF leakage at left C5–6 neural sleeve (arrow). b Axial reconstruction MRM of C-T spine indicates abnormal posterior epidural fluid accumulation (arrowhead). c Gd-T1WI sagittal MR of brain indicates pituitary hyperemia (arrow) and dural sinus engorgement (circle). d Gd-T1WI coronal MR of brain indicates pachymeningeal enhancement (arrowhead). e and f Axial reconstruction MRM of C-T spine at corresponding levels to (a and b) 1 month later indicate no spinal CSF leakage and no abnormal epidural fluid accumulation
