Concurrent Computed Tomography Angiography Spot Signs in Cerebral Contusion and Subdural Hematoma Following Severe Traumatic Brain Injury: A Case Report.
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
The spot sign is a well-established radiologic marker associated with hematoma expansion and poor clinical outcomes in spontaneous intracerebral hemorrhage. However, its role in traumatic intracranial hemorrhages remains insufficiently characterized. We report the case of a 67-year-old man who sustained a severe traumatic brain injury following a collision with a bicycle-driven cart. On presentation, his Glasgow Coma Scale score was 3T, with anisocoria (right pupil 1.5 mm; left pupil 4 mm). Computed tomography angiography revealed concurrent spot signs in a left-sided acute subdural hematoma (SDH) and a right temporal contusion. Emergent left decompressive craniectomy was performed for the SDH. Due to progressive hematoma expansion, a contralateral craniectomy was subsequently required for the temporal contusion. This case highlights the rare concurrence of spot signs in two distinct traumatic intracranial hemorrhages. Recognition of this imaging feature may enhance prognostication and guide urgent neurosurgical interventions in traumatic brain injury with multiple traumatic intracranial hemorrhages.
