Sacral CSF-venous fistula diagnosed using single-day bilateral decubitus myelography: A rare case and a novel technical modification.
Article in Radiology case reports, 2026. 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
CSF-venous fistulas are a common cause of spontaneous intracranial hypotension, a disease that can cause debilitating orthostatic headaches and a wide range of other symptoms. The vast majority of CSF-venous fistulas occur in the thoracic spine. Sacral CSF-venous fistulas are exceptionally rare but have been reported. While all CSF-venous fistulas require decubitus myelography with special modifications for detection, sacral CSF-venous fistulas can be particularly challenging to detect. Here, we describe a patient with a right S2 CSF-venous fistula. Additionally, we detail the specific myelographic technique that was necessary to detect this fistula. The case provides unique insights into a challenging radiologic diagnosis.
