Bilateral frontal arachnoid cyst rupture associated with chronic subdural hematoma following traumatic brain injury: a case report and literature review.
Article in International journal of surgery case reports, 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
Introduction: Chronic subdural hematoma (CSDH) and arachnoid cyst (AC) are distinct intracranial entities that may coexist, particularly following trauma. Although ACs are generally benign, their rupture can result in significant complications, including hemorrhage. Presentation of case: A 52-year-old male with bilateral frontal ACs and a history of epilepsy sustained a traumatic brain injury from a road traffic accident. One month later, he developed a severe headache, drowsiness, and syncope. Brain CT revealed bilateral CSDH secondary to cyst rupture. The patient underwent unilateral burr hole drainage, achieving complete hematoma evacuation and full neurological recovery. Follow-up MRI at 6 months showed no recurrence. Discussion: The association between AC rupture and CSDH likely involves trauma-induced tearing of bridging veins or cyst membranes. Early surgical management via burr hole drainage is typically curative, while craniotomy is reserved for refractory cases. Conclusion: Prompt recognition and minimally invasive treatment yield excellent outcomes in traumatic AC rupture with CSDH, though further studies are required to conclusively document these therapeutic outcomes in complex bilateral cases.
