An infantile case of posterior fossa arachnoid cyst presenting with marked engorgement of contralateral supraorbital vein.

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
A 6-month-old, previously healthy boy presented with poor feeding and vomiting for 2 weeks. At presentation, his left supraorbital vein was found to engorge considerably. A cranial computed tomography (CT) scan revealed a large cyst in the posterior fossa with a prominent left superior ophthalmic vein (SOV). Magnetic resonance imaging delineated the well-demarcated cyst markedly compressing the right cerebellar hemisphere. The patient underwent microscopic fenestration of the cyst wall through lateral suboccipital craniotomy. The cyst wall, comprising multi-layered, opacified membranes, was extensively resected and communicated with the prepontine cistern. The histological appearance of the cyst wall was consistent with an arachnoid cyst. Engorgement of the left supraorbital vein resolved immediately after surgery. A postoperative CT scan did not identify the SOV in the left orbit. In the present case, engorgement of the supraorbital vein might reflect the increased venous pressure of the SOV caused by compression of the contralateral cerebellar hemisphere.
