Cervical Schwannoma: A Rare Case Presentation - Neural Tissue Tumour.
Article in Annals of African medicine, 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
abstractCervical schwannomas are rare benign tumors that can present a significant diagnostic challenge, particularly when they exhibit cystic changes that mimic more common lesions such as second-branchial cleft cysts. We report the case of a 36-year-old male who presented with a gradually enlarging, firm, nontender neck mass. Imaging studies, including ultrasound and contrast-enhanced computed tomography, suggested a cystic lesion, most likely a second branchial cleft cyst. Fine-needle aspiration cytology was inconclusive. Surgical excision was undertaken, and histopathological examination revealed a schwannoma with areas of cystic degeneration. Immunohistochemistry demonstrated strong diffuse positivity for S100 protein, confirming the diagnosis. Postoperatively, the patient had an uneventful recovery without neurological deficits. This case highlights the importance of considering cervical schwannoma in the differential diagnosis of cystic neck masses and underscores the essential role of histopathology and immunohistochemistry in establishing an accurate diagnosis. Early recognition and complete surgical excision are key to achieving favorable outcomes.
