Symptoms of IH | headache double vision, papilledema | headache, visual disturbances | headache, visual disturbances | visual disturbances, papilledema | visual disturbances | visual disturbances | Headache, delirium |
Symptoms of previous CVST | headache, visual disturbances | isolated headache | headache, visual disturbances | isolated headache | headache, visual disturbances | visual disturbances | headache, paresis, focal seizures |
Recanalization status | partial | no recanalization | complete | partial | complete | no recanalization | partial |
