Three decades of colloid cyst resection

Purpose: To analyze 59 colloid cyst resections over 30 years at a single institution. Methods: Retrospective review of electronic health records, including surgical approaches: transcortical (18), transcallosal (36), and endoscopic (5). Results: Mean age at resection: 45.8 years. Cyst diameter: 4-27mm. Headache was the primary symptom (57.6%). Complications included memory deficits, infection, and neurological deficits; no mortality. Most cases were high-risk per Colloid Cyst Risk Score. Histology revealed pseudostratified epithelium (35%) and unique eosinophils. Craniotomy rate: 93%. Endoscopy had the highest reoperation rate; the transcallosal approach had more seizures and infections. Post-operative short-term memory issues: 40% (craniotomy), 50% (endoscopy). Conclusions: Findings largely align with literature, with notable differences in headache prevalence, gender ratio, histology, and endoscopy outcomes. This version reduces the word count by about 40% while retaining the essential information from each section. It maintains the structure and key points of the original abstract, allowing readers to quickly grasp the study's scope, methods, main findings, and conclusions.
