Clinical and imaging information in 10 patients with chronic, partially recanalized dural sinus thrombosis

Patient	Age	Sex	Symptoms	Symptom Duration before MR Imaging^*	Follow-Up (months)	Thrombosed Segments
1	39	M	Seizures	>1 Month	None	Right MTS, right LTS, right SS, right JB, torcular

3	47	M	Headache	45 Days from initial symptoms^†	MRI (27), TOF-MRV (12)	Left LTS, left SS, left JB
4	43	F	Headache	Follow-up 198 days from initial symptoms, initial acute scan 2 days after symptom onset^†	MRI (5), TOF-MRV (5), CE-MRV (5)	Right MTS, right LTS, right SS, right JB
5	52	M	None	Asymptomatic	MRI (24)	Right MTS, right LTS, right SS, right JB
6	52	M	Headache	10 days^†	MRI (6), TOF-MRV (6)	Left MTS, left LTS, left SS, left JB
7	49	F	Headache	Chronic headaches for 10 years	TOF-MRV (30)	Horizontal SSS, vertical SSS, right MTS, right LTS
8	23	F	Headache	Follow-up 55 days after initial symptoms, initial acute scan 4 days after symptom onset^†	TOF-MRV (10), CE-MRV (10)	Left MTS, left LTS, left SS, left JB
9	67	M	Neck pain, dizziness	Unknown	None	Right MTS, right LTS
10	76	M	Vertigo, hearing loss	60 days^†	None	Right LTS, right SS, right JB

Note:—Follow-up exams included magnetic resonance imaging (MRI), time-of-flight MR venography (TOF-MRV), and elliptic centric ordered contrast-enhanced MR venography (CE-MRV). Thrombosed segments included the medial transverse sinus (MTS), lateral transverse sinus (LTS), horizontal and vertical superior sagittal sinus (SSS), sigmoid sinus (SS), and jugular bulb/upper jugular vein (JB).
* Duration of symptoms prior to MR imaging in the chronic stage.
† Patients with clear onset of referable symptoms before imaging. In the remainder, the onset of symptoms was not defined precisely but was chronic (3 patients), was not obtainable from the medical record (1 patient), or the patient was asymptomatic (1 patient).
