A rare case of giant infrasellar craniopharyngioma with extensive invasion of the pterygopalatine fossa: A case report and literature review.
Article in Surgical neurology international, 2025. 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: Craniopharyngiomas are benign epithelial tumors that arise along the craniopharyngeal duct, commonly located in the sellar or suprasellar region. Infrasellar extension is a rare variant and may involve the nasopharynx, sphenoid sinus, clivus, and pterygopalatine fossa. Case Description: A 66-year-old male patient is presented to the otorhinolaryngology service due to a complaint of left ear obstruction for the past 4 months. After no response to clinical treatment, investigation with computed tomography and magnetic resonance imaging showed a heterogeneous lesion with areas of calcification and bone destruction located in the sphenoid sinus region, which projected inferiorly and laterally invading the clivus in its entirety, the petrous apex, middle fossa, pterygopalatine, and infratemporal fossae with no involvement of the sellar/suprasellar region. The patient was referred to a multidisciplinary skull base surgery group that performed an extended transpterygoid endoscopic endonasal approach with gross total resection. The anatomopathological study was consistent with adamantinomatous craniopharyngioma. Conclusion: We present a rare case of a giant infrasellar craniopharyngioma with extensive invasion of the skull base without involvement of the sella or the pituitary gland.
