Sequestered Lumbar Disc Mimicking Psoas Abscess: 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
We present a rare case of a sequestered lumbar disc herniation mimicking a psoas abscess. A 68-year-old male with a history of tongue cancer surgery had a ring-enhancing lesion in the left psoas muscle at the L2/3 level on contrast-enhanced computed tomography (CT), raising concerns about psoas abscesses related to vertebral spondylodiscitis. Magnetic resonance imaging (MRI) revealed a well-defined mass with low signal intensity on T1-weighted images, high signal intensity on T2-weighted images, and surrounding muscle edema. CT-guided biopsy revealed degenerative intervertebral disc tissue without malignancy or acute inflammation, confirming a sequestered disc herniation as the cause. Sequestered disc herniation is a rare condition in which the disc material migrates away from its origin, presenting similarly to infections or tumors. Imaging features such as ring enhancement in contrast studies can complicate the diagnosis. This case highlights the importance of considering sequestered disc herniation in the differential diagnosis of psoas muscle masses. Further research is needed to better understand the pathophysiology and management of sequestered disc herniation in the psoas muscle.
