Giant Arachnoid Cyst Presenting With Transient Facial Paresthesia: A Case Report.
Article in Cureus, 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
Arachnoid cysts are benign, cerebrospinal fluid-filled lesions that are frequently discovered incidentally on neuroimaging. Although most remain asymptomatic, large cysts may occasionally be associated with neurological symptoms due to mass effect or compression of adjacent structures. We report the case of a 61-year-old man who presented with transient numbness of the left side of the face. Brain computed tomography (CT) revealed a large right parieto-occipital arachnoid cyst with cerebrospinal fluid-like density, smooth margins, and thinning of the overlying calvaria, consistent with a long-standing lesion. The patient's symptoms resolved spontaneously, and no additional neurological deficits were observed during follow-up. This case illustrates the frequent dissociation between the striking radiologic appearance of giant arachnoid cysts and their limited clinical expression. Despite its size, the lesion was associated only with mild and self-limited symptoms, supporting a conservative management approach. Giant arachnoid cysts may remain clinically silent or present with transient symptoms. Clinical management should be guided by symptom severity and evolution rather than imaging findings alone in order to avoid unnecessary interventions.
