Sporadic hemangioblastoma of cauda equina: A case report and brief literature review.
Review in Journal of craniovertebral junction & spine. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Background: Hemangioblastomas (HBs) are rare lesions accounting for 1%-5% of all spinal cord tumors, and are mostly associated with Von Hippel-Lindau (VHL) syndrome. Localization in the cauda equina is uncommon. Aim: In this manuscript, we aimed to describe a rare case of sporadic intradural extramedullary HB of the cauda equina and present a literature review. Mathods: A systematic research was performed on PubMed, MEDLINE, and Google Scholar, using the keywords "spinal HB" and "cauda equina tumors." The previous literature is integrated by the description of the present case. A 49-year-old female presented in August 2020 to our institution with a magnetic resonance imaging (MRI) which showed an intradural mass at L1/2 level and angiography that showing a nidus of serpiginous vessels inside the lesion. Symptoms were right sciatica and paresthesia in right L5 radicular dermatome for more than 3 months. Neurological examination revealed claudicatio spinalis and hypoesthesia on right L5 dermatome and weakness of right anterior tibialis muscle. Microsurgical en bloc resection of lesion was performed with adjuvant neurophysiological intraoperative monitoring. The histological examination provided the diagnosis of HB. Results: After surgery, symptoms and neurological impairment gradually improved. Postoperative MRI showed no residual tumor. Conclusions: Although intradural extramedullary HB of the cauda equina without VHL syndrome is a rare pathological entity, this diagnosis must be taken in consideration when a mass affects cauda equina. Preoperative embolization is an option to minimize intraoperative bleeding. Radiosurgery seems to prevent recurrences when the tumor is not completely excised. A complete surgical removal of the lesion is usually possible and it leads to a low likelihood of recurrence.
