An exceptional localization of esophageal cancer: metastasis to the internal auditory canal.
Article in Oxford medical 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
Metastasis to the internal auditory canal (IAC) is rare, representing less than 1% of lesions in this region. We report the case of a 76-year-old man with a history of esophageal adenocarcinoma treated with chemoradiotherapy, who presented with progressive dizziness and unilateral hearing loss. Days later, he developed acute left peripheral facial paralysis. Magnetic resonance imaging revealed an enhancing IAC lesion associated with two cerebellar nodules. Vestibular testing confirmed a complete unilateral deficit. Positron emission tomography (PET) imaging showed hypermetabolic activity in all lesions, and a stereotactic biopsy of the largest cerebellar nodule confirmed the diagnosis of metastatic adenocarcinoma consistent with the esophageal primary. Despite supportive care, the patient died within one month. This case highlights the need to consider metastatic disease in atypical audiovestibular presentations in patients with a cancer history.
