The utility of stereotactic biopsy of intracranial lesions in the diagnosis of leukemia complicated by central nervous system lesions.

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
backgroundLeukemia complicated by central nervous system (CNS) lesions (LCNSL) includes leukemia involving the CNS (CNSL) and CNS secondary lesions related to leukemia treatment (e.g., CNS infections, leukoencephalopathy, inflammatory demyelination, and vascular diseases). The clinical manifestations and imaging characteristics of different types of LCL are similar, increasing the possibility of misdiagnosis. This study aimed to enhance our understanding and management of LCL.
methodsWe retrospectively collected clinical data from 22 patients with LCL and analyzed their magnetic resonance imaging and pathological characteristics. Pathological diagnoses were made using stereotactic intracranial puncture biopsy.
resultsBetween April 2003 and December 2023, 22 patients with LCL were admitted, including 18 males and 4 females aged 7-71 years. Bone marrow aspiration identified 14 cases of acute lymphoblastic leukemia (ALL), one of chronic lymphoblastic leukemia, six of acute myeloid leukemia (AML), and one of chronic myelomonocytic leukemia (CMML). Most patients presented with non-specific symptoms, including headache, nausea, vomiting, limb convulsions, and changes in mental status. A few patients had localized neurological deficits, such as limb weakness and blurred vision. Common systemic symptoms included fever, night sweats, and weight loss. The pathological diagnoses of the 22 patients were CNSL in 13 patients, CNS infections in five patients, and neurodegenerative diseases in four patients. Discrepancies were found between the clinical and pathological diagnoses in eight cases.
conclusionsStereotactic intracranial lesion biopsy is minimally invasive, safe, convenient, and critical in the early and differential diagnosis of LCL. Early identification of the lesions' nature and timely implementation of accurate and precise treatments can improve patient prognosis.
