Spontaneous Regression of Incidental Meningioma in the Posterior Cranial Fossa: A Case Report and Literature Review.

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
We report a rare case of spontaneous regression of a meningioma located in the posterior cranial fossa. A 60-year-old female patient presented with a headache. Both physical and neurological examinations were normal. Her medical history included type 2 diabetes mellitus. MRI showed a homogeneously enhancing mass in the left cerebellopontine angle. The volume of the tumor was 1.673 cm³. Radiological features, including the dural tail sign and the cerebrospinal fluid cleft sign, suggested the presence of a meningioma. Given these characteristics, we recommended serial follow-up MRI examinations. Unfortunately, the patient was lost to follow-up. Ten years later, she returned with a headache to reevaluate the previously diagnosed tumor. The follow-up MRI revealed significant regression and increased intratumoral calcification, with the tumor now measuring only 0.256 cm³. This report illustrates that meningiomas diagnosed incidentally can undergo spontaneous regression, a phenomenon that clinicians should be aware of.
