Rituximab induced cerebral venous sinus thrombosis in a patient with anti-N-methyl-D-aspartate receptor-antibody encephalitis: a case report and review of literature.
Review in Journal of medical case reports, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundCerebral venous sinus thrombosis has not been reported in anti-N-methyl-D-aspartate receptor-antibody encephalitis in the absence of an underlying thrombotic state while rituximab induced cerebral venous sinus thrombosis is rarely reported. We report a patient with anti-N-methyl-D-aspartate receptor-antibody encephalitis without a prothrombotic state who developed cerebral venous sinus thrombosis following rituximab treatment. CASE PRESENTATION: A 15-year-old Sri Lankan girl who had been in remission following an episode of anti-N-methyl-D-aspartate receptor-antibody encephalitis 2 years ago, presented with a relapse of anti-N-methyl-D-aspartate receptor-antibody encephalitis characterized by recurrent seizures, mutism, and cognitive abnormalities. Since response was inadequate to first-line immunotherapy, she was administered four doses of rituximab at weekly intervals. Two days after the fourth dose, she developed increasing headaches, and her cranial magnetic resonance venogram confirmed the development of cerebral venous sinus thrombosis. Screening for prothrombotic states were negative. She made an unremarkable recovery following anticoagulation.
conclusionThis case highlights the occurrence of the rare but serious complication of cerebral venous sinus thrombosis following rituximab in the context of anti-N-methyl-D-aspartate receptor-antibody encephalitis and informs the clinician to be wary of new onset headache in patients with anti-N-methyl-D-aspartate receptor-antibody encephalitis treated with immunotherapy.
