CSF dissemination of EGFR-mutant lung cancer present as cranial nerve injury and masticator muscle denervation: a case report and literature review.
Article in Oxford medical case reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Lung cancer with central nervous system metastases are troublesome clinical scenarios. Rare and diagnostically challenging presentations with subtle image findings may delay diagnosis. We report one case with advanced non-small cell lung cancer. A 48-year-old female present with chewing difficulty, diplopia and facial asymmetry. Magnetic resonance imaging of the brain revealed edematous swelling and abnormal enhancement over bilateral masticator muscles, and faint enhancement over origins of cranial nerves near brainstem. Therefore, masticator muscle denervation related to cranial nerve injury was diagnosed. Symptomatic and disease control was achieved after double dose osimertinib which provide novel insights in the treatment of EGFR-mutant lung cancer with cranial nerve involvement. Chewing difficulty is an exceptional clinical presentation in lung cancer and may lead to delayed diagnosis in case of unawareness. In addition, radiological detectable bilateral masticator muscle denervation is rarely seen and has not been published in the field of lung cancer.
