Purpose Isolated deep cerebral venous thrombosis (DCVT) may have different presentation and outcome compared to DCVT with additional sinus thrombosis. We compare clinico-radiological findings and outcomes of patients with isolated DCVT with those having additional sinus thrombosis. Methods Forty-one DCVT patients with or without additional sinus thrombosis were included. Deep CVT was diagnosed if there was thrombosis of straight sinus, vein of Galen, internal cerebral vein, or basal vein of Rosenthal on MR venography (MRV). Isolated DCVT patients were classified as Group A and those with additional sinus thrombosis as Group B. The clinical features, risk factors, MRI findings, and outcomes at 1, 3, and 6 months were compared between Groups A and B. Results Median age was 28 years, and 22 (54%) were females. Eight (19.5%) patients were in Group A and 33 (80.5%) in Group B. Group B patients had shorter duration of illness (7 vs 30 days; p  = 0.01), frequent vomiting [25 (75.7%) vs 2 (25%); p  = 0.01], and papilledema [13 (39%) vs 0 (0%); p  = 0.04]. Risk factors were comparable. MRI revealed bilateral thalamic [5 (62.5%) vs 6 (18.2%)] and basal ganglia [(4 (50%) vs 6 (18.2%)] lesions more frequently in Group A. At 1 month, 2 (6%) patients died in Group B and none in Group A, and 24 had good outcome (50% Group A and 60.6% in Group B). At 3 months, 30 had good outcome (62.5% Group A and 80.6% in Group B). Improvement after 3 months was negligible. Conclusion Isolated DCVT is rare, and additional sinus thrombosis is associated with more severe illness and death. However, long-term outcomes in the survivors are similar between the two groups.
