| Patient No. | Age (yr) | Sex | Opening Pressure (cm H2O) | Leak Detected on CTM | Leak Detected on MR Myelogram | Time Difference (h:min) | Extent of Extra-Arachnoid Contrast | Same-Day Blood Patch | Suspected CSF Leak Etiology |
|---|---|---|---|---|---|---|---|---|---|
| 1 | 66 | Female | 5 | No | Yes | 0:37 | T6–T12 | No | Unclear; spinal diverticula C6–C7 through L2–L3 |
| 2 | 62 | Male | 7 | No | Yes | 1:14 | T9–L1 | Yes | Bilateral T9–T10 spinal diverticula |
| 3 | 27 | Male | 10 | Yes | Yes | 0:55 | L2–L5 | No | Dural ectasia; marfanoid features |
| 4 | 52 | Male | 7 | No | Yes | 1:14 | T6–T12 | Yes | Bilateral T9–T10 and left T11–T12 spinal diverticula |
| 5 | 32 | Female | 0 | No | Yes | 0:29 | C3–L1 | No | No source of leak detected; T2–T3 leak seen on subsequent fluoroscopic subtraction myelogram |
| 6 | 37 | Female | 6 | Yes | Yes | 5:14 | T10–L1 | Yes | T11–T12 disk osteophyte; blood patch performed before MRM |
| 7 | 55 | Male | 8 | No | Yes | 0:49 | T5–T6 and T9–T10 | No | Right T5–T6 and left T9–T10 spinal diverticula |
| 8 | 55 | Male | 6 | No | Yes | 0:12 | T7–T8 | Yes | Right T7–T8 spinal diverticula |
| 9 | 58 | Female | 0 | Yes | Yes | 0:46 | C7–T4 | No | T1–T2 secondary to disk protrusion and dural tear |
↵a The time difference reflects the time stamp difference between CTM acquisition and the beginning of MRM. A same-day blood patch was performed when logistically possible and a clear source of leak was identified.
