Hypertensive brainstem encephalopathy with isolated headache and blurred vision: A case report.
Article in eNeurologicalSci, 2026. 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
Background: Headache with papilledema is a critical neurological symptom that necessitates prompt evaluation for underlying central nervous system pathology. While often associated with conditions such as aneurysmal subarachnoid hemorrhage, hypertensive emergencies can also present with similar features and require immediate management to prevent end-organ damage. Case presentation: A 41-year-old man with no significant medical history presented with acute severe headache, vomiting, and blurred vision in the left eye. His blood pressure was markedly elevated at 200/130 mmHg. Fundoscopic examination revealed optic disc swelling, flame-shaped hemorrhages, and exudates in both eyes. Brain MRI demonstrated asymmetric hyperintensities in the brainstem, consistent with hypertensive brainstem encephalopathy (HBE). Lumbar puncture revealed elevated intracranial pressure without evidence of infection or hemorrhage. Blood pressure control with intravenous calcium channel blockers resulted in rapid symptom resolution, and subsequent antihypertensive therapy led to complete recovery of brainstem lesions and significant improvement in papilledema. Conclusion: HBE can present with severe headache and papilledema but minimal neurological deficits despite striking MRI abnormalities. Early recognition through neuroimaging and prompt blood pressure management are crucial in preventing irreversible damage and optimizing patient outcomes.
