1. Patient 2.
Patient 2. A 62-year-old man with headache and recurrent subdural hemorrhage following evacuation, found to have imaging findings of SIH. Axial CTM (A) and MRM (B) images at the T9–T10 level. Spinal diverticula are evident on both examinations. The MRM demonstrates an extra-arachnoid contrast collection and ill-defined increased T1 signal surrounding the enlarged right spinal diverticula. Subsequent CT performed for epidural blood patch planning with a localization grid in place (C) shows the spinal diverticula; the extra-arachnoid contrast collection is not evident. The patient reported symptomatic relief following directed blood patch and was without headache as of the 2-month follow-up note.
