Patient demographics, imaging findings, symptoms, treatment, and outcomes

Patient	Age	Sex	Other Imaging Findings	CTM Findings	Symptoms	Treatment	Outcome
1	28	F	High-probability brain MR imaging	T12-L1 CVF on left; T11-12 on right; contrast in the renal collecting system	Orthostatic headache, multifocal pain	T11 nerve root ligation	Initial relief with subsequent recurrence of symptoms in the setting of Marfan syndrome
2	50	M	Intermediate-probability brain MR imaging	CVF at left L2-3 and contrast in the renal collecting system	Orthostatic headache	Blood patch, transvenous embolization of the left L2 paraspinal vein	Dramatic symptom improvement following embolization
3	52	M	High-probability brain MR imaging, positive cisternogram findings	Right T10 distal nerve root sleeve tear with extradural contrast first detected at L2-3	Orthostatic headache, vision changes, pulsatile tinnitus	Hemi-laminectomy right T10-11, repair of CSF leak	Complete symptom resolution sustained for at least 1 year
4	34	F	Intermediate-probability brain MR imaging	Focus of CSF leak arising from the right lateral thecal sac at T7-8 thought to represent dural tear; contrast in the renal collecting system	Orthostatic headache, facial and hand paresthesia	Three targeted blood patches	Improvement after 3 targeted blood patches with recurrence of symptoms
5	50	F	Multiple nerve root diverticula on spine MR imaging	Faint linear hyperattenuation extending from a right T11-12 nerve sleeve diverticulum thought to represent CVF	Orthostatic headache, vision changes	Two targeted and 1 multifocal blood patch	Transient improvement after 2 targeted and 1 multifocal blood patch
