Preoperative Cerebellar Mutism Syndrome in an Adult Female With a Fourth Ventricle Epidermoid Cyst: A Case Report and Review of the Literature.
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
Cerebellar mutism syndrome (CMS) is typically a postoperative complication of posterior fossa tumor resection, especially in pediatric medulloblastoma. We report a rare case of preoperative CMS in a 67-year-old woman with a fourth ventricle epidermoid cyst. She presented with dizziness, gait instability, emotional lability, and speech arrest. MRI revealed a multilobulated mass occupying the fourth ventricle and extending into the cerebellar hemispheres. After total surgical resection and ventriculoperitoneal shunt placement, histopathology confirmed an epidermoid cyst. The patient progressively regained speech and gait stability, with complete speech recovery and no recurrence at three-year follow-up. This case suggests that mass effect on the dentato-thalamo-cortical pathway can produce reversible preoperative CMS in adults and that recognition of this entity is essential for surgical planning and prognosis.
