Progressive Quadriparesis of a Toddler with a Posterior Cranial Fossa Arachnoid Cyst (AC): Illustrative Case Report and Narrative Literature Review.
Article in Children (Basel, Switzerland), 2024. 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/
objectivesIntracranial arachnoid cysts (ACs) may be congenital, primary, or secondary due to trauma. These cysts are benign, contain cerebrospinal fluid (CSF), and are classified based on location, size, and their clinical symptomatology. They are uncommon lesions in children, rarely leading to severe mass-effect neurological symptomatology.
methodsThe present report describes a 30-month-old female presenting with quadriparesis. An emergency magnetic resonance imaging (MRI) study revealed the presence of a primary intracranial arachnoid cyst of the posterior cranial fossa, exerting significant pressure on the medulla oblongata and the cervical portion of the spinal cord, displacing them dorsally, with a remnant diameter of 2.5 mm.
resultsThis benign malformation located in a crucial area might have been complicated by severe neurological deterioration and required prompt intervention, so the patient underwent a suboccipital craniectomy in a sitting position, along with a neurosurgical procedure, which established a lasting communication channel between the cyst and the basal cisterns. This led to a favorable outcome.
conclusionsUp to the present report, postoperative complete resolution of quadriparesis secondary to a posterior cranial fossa arachnoid cyst has not been reported. At present, no therapeutic modality has been established as the definitive standard of care for pediatric ACs, and their management raises a great deal of controversy among neurosurgeons. The narrative literature review of the present study integrates the various perspectives regarding ACs and their possible treatment approaches that are currently available.
