Endoscopic resection of a giant colloid cyst in the cavum septum pellucidum: Illustrative case
Abstract
Background: Colloid cysts (CCs) are a rare type of benign tumor, and the ones >30 mm in diameter are determined as giant CCs. The giant CCs of the cavum septum pellucidum (CSP) are located in the hard-to-reach areas of the brain, and they can be removed microsurgically and endoscopically. At present, the transition from the microsurgical resection to the endoscopic is observed, and researchers demonstrate several benefits of the endoscopic resection over the microsurgical. We noticed the absence of research illustrating the endoscopic resection of the giant CC of the CSP. Therefore, we decided to demonstrate a rare case performed in our hospital.
Case description: Our patient was a 57-year-old male who had suffered from dizziness, headache, nausea, urinary incontinence, short-term forgetfulness, gait ataxia, cognitive decline, and vision blurring. The eventual diagnosis of the giant CC in the CSP was established, and it was complicated by occlusive hydrocephalus and headache syndrome. The endoscopic resection of the giant CC in the septum pellucidum was performed using the endoscopic transseptal approach.
Conclusion: No complications were observed in the postoperative period. The tumor was removed completely, no recurrence was noted, and only a capsule of the tumor was observed in the control magnetic resonance imaging image taken 3 months after the operation. Considering these results, we conclude that endoscopic removal may have positive and safe outcomes as the surgical…
How strong is the evidence?
Evidence Hub reads this as a case report, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.
