Objectives: Cerebral venous sinus thrombosis (CVST) is a disease with potentially serious consequences. The clinical presentation and outcomes of these patients have not been described in Oman. We sought to describe the clinical characteristics and outcomes of patients with CVST. Methods: We conducted a retrospective study in two tertiary care centers in Oman, which included all Omani adults with radiologically confirmed CVST. We recorded and analyzed patients’ demographic, clinical, and outcome data. Results: Fifty-four patients had radiologically confirmed CVST. The commonest presenting feature was headache (85.0%), followed by focal motor deficits (48.0%) and seizures (27.0%). In this cohort, 24.0% were pregnant or postpartum, 11.0% had an inherited thrombophilia, 11.0% were on hormonal therapy, and 11.0% had systemic lupus erythematous; 38.9% of patients had multiple sinus thrombosis while 35.2% had sigmoid and transverse sinus thrombosis. Antiphospholipid antibody syndrome and infection accounted for 7.0% and 13.0% of causes, respectively, while cancer accounted for 2.0%. No cause was identified in 33.0% of cases. Only 1.9% of patients died, while 29.6% had a residual neurological deficit at hospital discharge. Age was a predictor for residual neurological deficit (p = 0.003). Conclusions: Pregnancy and postpartum were the most common predisposing factors for CVST in our cohort. Although the mortality rate is low, the risk of residual neurological deficit remains high. We recommend a prospective study for better characterization and outcome assessment.
