Fatal malignant cerebral vasospasm following pediatric craniopharyngioma resection: A case report and literature review.
Article in Surgical neurology international, 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: Cerebral vasospasm is a rare but devastating complication following intracranial tumor surgery, particularly in pediatric suprasellar lesions such as craniopharyngiomas. Delayed cerebral ischemia secondary to postoperative vasospasm remains insufficiently recognized and may result in fatal neurological injury. Case Description: We report the case of a 5-year-old girl who underwent gross total resection of a cystic suprasellar craniopharyngioma through a subfrontal approach without intraoperative vascular injury. The immediate postoperative course was uneventful. On postoperative day 6, the patient developed sudden refractory status epilepticus associated with rapid neurological deterioration and bilateral fixed mydriasis. Brain computed tomography (CT) revealed extensive left hemispheric ischemia with severe cerebral edema. CT angiography demonstrated marked narrowing of the A1 + M1 segment of the left middle cerebral artery, consistent with malignant cerebral vasospasm. Despite intensive care management, the patient progressed to brain death and subsequently died. Conclusion: Delayed malignant cerebral vasospasm following pediatric craniopharyngioma resection is an unpredictable and potentially fatal complication that may occur even in the absence of intraoperative vascular injury. Prompt recognition of delayed neurological deterioration and early vascular imaging are crucial to improve diagnostic and therapeutic management.
