“…Postoperative delayed recurrence for CES Spinal schwannomas, accounting for 31-49% of cauda equina tumors in adults, are the third most common primary tumor of the spinal cord, meninges, and cauda equina. [3,5,12] Further, they are typically well-defined benign tumors that are often treated with surgery alone. [3,8,12] Nevertheless, there are reports of delayed recurrences of spinal schwannomas [Table 2].…”

[3,8,12] Nevertheless, there are reports of delayed recurrences of spinal schwannomas [Table 2]. [1,9,12] Wager et al reported total removal in over 99% of patients with CES; a low recurrence rate suggested that imaging beyond 24 months were not required.…”

Background: Cauda equina tumors are rare primary spinal tumors. Histologically, the most common tumor arising from the cauda equina is a schwannoma. However, little is known about the long-term postoperative outcomes of cauda equina schwannoma. Here, we reviewed the median-to-long-term postoperative outcomes of eight of our own patients with schwannomas of the cauda equina. Methods: Between 2007 and 2020, we, retrospectively, reviewed eight patients with cauda equina schwannomas (CESs) undergoing nine operations at our institution. There were five males and three females averaging 56.5 years of age who were followed for over 40 postoperative months. The study included assessment of the following variables: the modified McCormick scale, tumor size, location, extent of resection, treatment of the tumor involving nerve roots, and postoperative observational follow-up. Results: Gross-total resection was achieved in all eight patients; none received adjuvant therapy. The involved nerve roots were completely sacrificed in seven patients and partially resected in one. During a median follow-up of 108 months, only one patient sustained a tumor recurrence 164 months following the index surgery. Conclusion: CESs may recur more than 10 years after the original surgery. Radical resection of the tumor, including complete removal of the involved nerve root during the index surgery, and long-term postoperative follow-up is, therefore, essential.

“…Primary neoplasms involving the cauda equina are most commonly schwannomas and ependymomas. 14 Although 1.7% of primary cauda equina tumors (5/293) reported to the National Cancer Institute’s Surveillance, Epidemiology, and End Results (SEER) database were categorized as GBM, 14 no other reports of cauda equina GBM cases were found upon review of the literature highlighting the unique nature of a tumor occurring in this location. GBM lesions are usually supratentorial, occurring most frequently in the frontal lobe or across multiple cerebral lobes.…”
