Tectal Plate Glioma Presenting With Intratumoral Hemorrhage.
Article in Cureus, 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
Tectal gliomas are rare brainstem tumors. These tumors typically cause obstructive hydrocephalus due to mass effect on the cerebral aqueduct; however, intratumoral hemorrhage is exceedingly rare, with only one previously documented case to our knowledge. Patients typically present with symptoms of hydrocephalus, including headaches, nausea, and visual disturbances. We report the case of a 43-year-old man with a known tectal plate glioma who presented with acute obstructive hydrocephalus secondary to intratumoral hemorrhage. Following the patient's rapid neurological decline, computed tomography (CT) and magnetic resonance imaging (MRI) confirmed the diagnosis. The patient underwent an endoscopic third ventriculocisternostomy (ETV) for cerebrospinal fluid diversion, along with an endoscopic biopsy of the tectal mass. The patient's postoperative course was favorable, with gradual resolution of symptoms, including diplopia and headaches. A follow-up MRI revealed reduced tumor size and stable ventriculomegaly. Histopathological analysis suggested the tumor to be of glial origin and low-grade in nature, based on its contrast enhancement on MRI and the patient's clinical trajectory. This case illustrates a rare presentation of intratumoral hemorrhage in tectal gliomas, emphasizing the need for heightened clinical suspicion in such cases. ETV remains an effective treatment for obstructive hydrocephalus, though the potential for hemorrhagic complications warrants close monitoring.
