Primary central nervous system lymphoma (PCNSL) mimicking a falx meningioma with increasingly massive intracerebral hemorrhage.
Article in Radiology case reports, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
When using imaging to diagnose brain tumors, it is important to determine whether the tumor is intra- or extra-parenchymal. An 80-year-old man was found on magnetic resonance imaging to have an enhanced mass that appeared to be in the falx and a massive hematoma in the left frontal lobe; the provisional diagnosis was falx meningioma. However, the tumor and hematoma were found intraoperatively to be completely intraparenchymal. Additionally, the falx was intact and not adherent to brain tissue. Malignant lymphoma was diagnosed histologically on the basis of abnormal proliferation of atypical CD20-positive lymphocytes. Cerebral hemorrhage is an extremely rare presentation of primary central nervous system lymphoma. To the best of our knowledge, only 7 cases have been reported. All the reported cases had enhancement in the hematoma; however, in our case, there was definite enhancement outside the hematoma, making the correct diagnosis of lymphoma difficult.
