Hypertensive crisis during embolization unveils occult catecholamine-secreting glomus jugulare tumor: A case report and management protocol.

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
Glomus jugulare tumor (GJT) is a rare paraganglioma arising from neural crest cells. Although the majority of cases are non-functional, a minority of GJTs can secrete catecholamines. Such functional variants are frequently overlooked due to their rarity and may trigger perioperative crises. The present report documents a 53-year-old female patient with a giant occult secretory GJT (65 mm) presenting with prolonged cranial nerve deficits. Preoperative blood pressure was normal, but the patient developed hypertensive crisis (220/130 mmHg) during embolization. Biochemical tests confirmed catecholamine excess. Hemodynamic stability was maintained using calcium channel blockers without α-blockade after embolization. Tumor resection was performed within 72 h, achieving total resection without intraoperative crisis. Catecholamine levels normalized postoperatively with marked neurological improvement. The present case highlights the importance of recognizing occult secretory GJTs and discusses key management considerations regarding preoperative preparation, timing of surgery and anesthetic management. Increased awareness may improve diagnosis and optimize outcomes in these challenging cases.
