Abstract
This particular case is a world-first with no previous literature reports on patients presenting with both benign acoustic schwannoma and malignant ependymoma. A 60-year-old woman with unexplained right-sided hearing loss that had worsened progressively over 4 years, along with intermittent dizziness that had begun 3 years prior. Our preliminary diagnosis included: (1) Right acoustic neuroma; (2) Ependymoma of the fourth ventricle; and (3) Hydrocephalus. We employed the right sigmoid sinus posterior approach combined with the posterior median approach, beginning with removal of the fourth ventricle tumor and then proceeding to acoustic schwannomas resection through rotating operation positions. The case presented significant challenges owing to: The difficulty encountered in arriving at a diagnosis; The difficulty in choosing a suitable surgical approach; The complexity of the surgical sequence; The intricacy of the surgical process. It's rare, complex, and had excellent surgical results.
Overview
- The study presents a rare case of a 60-year-old woman with unexplained right-sided hearing loss and intermittent dizziness, diagnosed with both benign acoustic schwannoma and malignant ependymoma.
- The patient underwent a unique surgical procedure using the right sigmoid sinus posterior approach combined with the posterior median approach.
- The study aims to present a rare case with complex surgical challenges, highlighting the importance of accurate diagnosis, suitable surgical approach, and precise surgical sequence.
Comparative Analysis & Findings
- The study presents a unique case with no previous literature reports of patients presenting with both benign acoustic schwannoma and malignant ependymoma.
- The patient's condition was diagnosed using preliminary diagnosis including Right acoustic neuroma, Ependymoma of the fourth ventricle, and Hydrocephalus.
- The surgical procedure employed a rotating operation position to remove the fourth ventricle tumor and then proceed with acoustic schwannomas resection.
Implications and Future Directions
- The study highlights the importance of accurate diagnosis and suitable surgical approach in rare and complex cases.
- Future studies should focus on developing novel approaches and techniques to improve surgical outcomes in similar cases.
- The study also emphasizes the significance of careful planning and execution of surgical procedures in patients with rare and complex conditions.
