Metastatic High-Grade Serous Ovarian Carcinoma Presenting as a Temporal Lobe Glioblastoma Mimic: A Diagnostic Pitfall.
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
High-grade serous ovarian carcinoma (HGSOC) is the most common subtype of ovarian cancer, known for its aggressive nature and unique pattern of metastasis. Brain metastases from ovarian carcinoma are uncommon, with HGSOC rarely presenting with multifocal lesions that radiographically mimic the multi-centric growth pattern of a primary glioblastoma, particularly following a prolonged period of clinical remission, leading to diagnostic ambiguity. We report the case of a 69-year-old woman with a prior history of HGSOC who presented with new-onset cognitive and language deficits. Neuroimaging indicated a prominent temporal lobe mass radiologically suggestive of glioblastoma. Histopathological examination and immunohistochemistry demonstrated features consistent with metastatic HGSOC, showing strong paired box gene 8 (PAX8) positivity and absence of glial markers. This case highlights the importance of considering a range of differential diagnoses for intracranial lesions in patients with a history of malignancy by using a multidisciplinary approach to interpret clinical, radiologic, and histopathologic data, while emphasizing the crucial role of immunohistochemistry in distinguishing metastatic disease from primary brain tumors.
