Primary Intraparenchymal Solitary Malignant Melanoma of the Brain Without Dural Attachment: A Rare Case With Local Recurrence.
Article in Cureus, 2026. 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
Malignant melanoma is a neoplasm arising from the malignant transformation of melanocytes. These cells are derived from the neural crest and are found predominantly in the skin, but also in mucous membranes, the uveal tract of the eye, the leptomeninges, and other sites. A 39-year-old previously healthy male presented with a holocranial headache for two months and a single episode of a focal seizure involving his left arm. Neurological exam revealed left-sided pronator drift and gross papilledema. Contrast-enhanced magnetic resonance imaging (CE-MRI) of the brain revealed a large (4.8 x 3.9 cm) heterogeneously enhancing lesion in the right parieto-occipital region with marked perilesional edema, with the provisional diagnosis of a high-grade lesion. Complete metastatic work-up, including computerized tomography (CT) of the chest and abdomen and positron emission tomography (PET), revealed no primary lesion; hence, the lesion was planned for excision. Gross total excision (GTE) was achieved, and histopathological examination (HPE) of the resected specimen confirmed malignant melanoma. Recurrence was noted 11 months later with an even bigger lesion (6.0 x 5.0 cm) on CE-MRI, and the patient succumbed to death 45 days later under the care of oncology for adjuvant chemotherapy. Primary intracerebral malignant melanomas are extremely rare tumours of the CNS. Despite surgical and chemotherapeutic treatment options, these tumours are a clinical ordeal due to their aggressive behaviour and explosive growth rate. The primary existence of melanoma intracerebrally is an oncologic enigma and needs to be included in the differential diagnosis of primary brain lesions.
