Unilateral expanding petrous apex cephalocele and contralateral vitreous hemorrhage in a young patient with intracranial hypertension.

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
purposeTo report a case of unilateral petrous apex cephalocele (PAC) and contralateral vitreous hemorrhage in a young patient with intracranial hypertension. OBSERVATIONS: A 12-year-old boy had acute visual loss in the right eye. The clinical and radiological findings were consistent with right vitreous hemorrhage with mild intracranial hypertension and left PAC. Cerebral angiography demonstrated low flow of the left inferior petrosal sinus and anterior venous high flow from the cavernous sinus to the facial vein via the superior ophthalmic vein. The presence of an expanding PAC, blocking the venous flow away from the inferior petrosal sinus, would produce an ipsilateral intraocular pressure (IOP) (20 mmHg) mildly higher than the other one (16 mmHg) although it is in the normal range, which may have caused the difference of the translaminar pressure gradient resulting from the balance between the cerebrospinal flow pressure and the IOP. CONCLUSION AND IMPORTANCE: Unilateral expanding PAC may cause intracranial hypertension with different severity of papilledema between two eyes.
