In CENETs, the coexistence of SS, intratumoral FFL, and marked hypervascularity on preoperative imaging may indicate a chronic hemorrhagic phenotype with severe adhesions to the cauda equina, particularly in large multisegmental tumors. In such cases, nerve-sparing subtotal resection planned with preoperative vascular assessment and performed under intraoperative neurophysiological monitoring can be an appropriate strategy to balance tumor control with preservation of neurological function when safe dissection planes are limited. https://thejns.org/doi/10.3171/CASE251015.
