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).
