Hypertrophic pachymeningitis caused by Schizophyllum sp.: a novel case report.
Article in Infection, 2021. 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
backgroundThe pathogenic fungus Schizophyllum sp. can cause allergic fungal rhinosinusitis and allergic bronchopulmonary mycosis in humans. Sinus and lung infections due to Schizophyllum sp. have been reported globally; however, no case of hypertrophic pachymeningitis due to this pathogen has been reported yet. Herein, we describe for the first time, a case of hypertrophic pachymeningitis due to Schizophyllum sp. CASE PRESENTATION: A 69-year-old woman visited the hospital with chief complaints of headache, right trigeminal neuralgia (third branch), ataxic gait, and deafness in the right ear. Magnetic resonance imaging revealed a tumor in the right sphenoidal sinus and thickening of the dura mater surrounding the right porus acusticus internus. Endoscopic sinus surgery and neuroendoscopic biopsy were performed to remove sinus lesions and intracranial lesions, respectively. Both pathological specimens showed findings indicative of filamentous fungi on Grocott's staining. DNA sequencing with the sinus specimen revealed Schizophyllum sp. as the causative pathogen, consistent with the diagnosis of fungal sinusitis and hypertrophic pachymeningitis. Intravenous liposomal amphotericin B was started, but owing to lack of improvement, the treatment was switched to intravenous voriconazole. We observed improvements in both radiological findings and symptoms. However, the symptoms exacerbated again when the trough level of voriconazole decreased. Upon increasing the voriconazole dose, a higher trough level was obtained and the symptoms improved.
conclusionOur study suggests that when symptoms of central nervous system infection due to Schizophyllum sp. do not improve with liposomal amphotericin B, voriconazole can be administered at high trough levels to improve the symptoms.
