A Rare Cause of Acute Dysphagia: Listeria Rhombencephalitis.
Article in European journal of case reports in internal medicine, 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: Acute dysphagia is a common presentation to hospital and requires a structured diagnostic approach to distinguish between oropharyngeal and oesophageal causes. Although oesophageal pathology is often suspected, central neurological causes must be considered, particularly in atypical presentations. Case report: A 37-year-old male presented with acute onset dysphagia and an inability to manage oral secretions following a short prodrome of fever and gastrointestinal symptoms. Initial evaluation suggested oesophageal obstruction; however, urgent endoscopy was unremarkable. His condition deteriorated with aspiration pneumonitis and persistent dysphagia. In the presence of reduced lingual sensation and impaired gag reflex, neuroimaging and lumbar puncture were performed, confirming Listeria rhombencephalitis. Despite targeted antimicrobial therapy, he developed multiple cranial nerve deficits and required a tracheostomy for airway protection. With prolonged intravenous antibiotics and multidisciplinary care, he demonstrated gradual neurological recovery and was discharged for ongoing rehabilitation. Conclusion: This case highlights the importance of a systematic diagnostic framework in acute dysphagia and maintaining a high index of suspicion for alternative causes to avoid diagnostic anchoring. Early recognition of oropharyngeal features and neurological signs should prompt timely neuroimaging and lumbar puncture. Central causes including Listeria rhombencephalitis should be considered early, as prompt targeted therapy is essential to improve outcomes. LEARNING POINTS: Acute dysphagia requires a structured and careful diagnostic approach to differentiate between oropharyngeal and oesophageal dysphagia.Investigation of acute dysphagia should occur in parallel across differential diagnoses, with a high index of suspicion maintained in atypical presentations.Listeria rhombencephalitis should be considered in immunocompetent patients with suggestive clinical signs and symptoms.
