Isolated Intraventricular Metastatic Melanoma: 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
Isolated intraventricular melanoma is an infrequent disease presentation that poses unique diagnostic and management challenges. Of the few cases reported in the literature, each has a unique management plan. We present the case of a 64-year-old female with a history of gallbladder melanoma in remission after multiple cycles of chemotherapy and immunotherapy. After eight years, the patient was presented to the emergency department due to cognitive changes, memory issues, headaches, and vomiting. Imaging showed diffuse, bulky, nodular enhancement of bilateral ependyma of the lateral ventricles of unclear etiology. Systemic imaging revealed no additional sites of metastatic disease. Cytologic evaluation through multiple cerebrospinal fluid (CSF) aspirations via lumbar punctures produced unremarkable results. An external ventricular catheter was subsequently placed directly into the right lateral ventricle with no CSF able to be aspirated. Through modulated suction and aspiration, a biopsy sample was obtained through this catheter. Molecular testing of the specimen facilitated the initiation of targeted, combination chemo- and immunotherapies in conjunction with whole-brain radiation therapy. This multidisciplinary, personalized treatment plan ultimately resulted in considerable regression of her ventricular disease burden. This very rare disease presentation, along with our novel approach for tissue sampling, highlights the importance of obtaining specimens for molecular testing to guide targeted therapies that optimize patient outcomes, particularly in instances in which lumbar CSF fails to result in diagnostic yield.
