Lumbar angiomatous meningioma: how to manage this rare entity? A case report.

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
introductionSpinal meningiomas (SM) are rare intradural extramedullary tumors arising from arachnoid cells of the leptomeninges. They are most commonly found in the thoracic region, with angiomatous subtypes being even rarer and carrying a high hemorrhagic risk. Diagnosis and treatment are guided by clinical presentation and imaging, with surgery being the primary therapeutic approach. Recurrence is uncommon, occurring in 1.3 % to 6.4 % of cases, and decisions between surgery and adjuvant treatments like radiotherapy depend on factors such as tumor location, histological subtype, and the surgeon's expertise. This case aims to explore the radiological features and treatment strategies for SM. CASE PRESENTATION: A 58-year-old man with a history of disc herniation surgery presented with lower back pain, bilateral sciatica, cruralgia, and sphincter dysfunction. Spinal MRI revealed an intra-dural, extra-medullary tumor, which was surgically removed and the patient had an uneventful postoperative recovery. Histopathological examination confirmed an angiomatous meningioma (WHO Grade 1). CLINICAL DISCUSSION: SM are rare tumors, often causing pain and neurological issues. Imaging is crucial in assessing tumor extent and vascularization, helping in treatment decisions. Although recurrences aren't common, they are usually treated surgically, with adjuvant therapies like radiotherapy being considered for high-grade or inoperable tumors. Further research is needed to refine the understanding and management of spinal meningiomas.
conclusionSM are exceptional, mostly benign, slow-growing tumors, with surgical resection remaining the primary treatment and offering low recurrence rates. Adjuvant therapies, including radiotherapy and molecular-targeted treatments, remain largely investigational, with no established clinical application.
