Abstract
Sacral schwannomas are very rare and encompass approximately 1%–5% of spinal schwannomas. Due to their benign nature and slow growth, these tumors are often giant and become difficult to treat. Their removal is a surgical challenge with different strategies reported in the literature. Presacral Schwannomas encased by the internal iliac vein are rare with not many instances of such a case found in literature. This is a case in which the venous encasement was found intraoperatively, following which the surgery was abandoned to avoid excess intraoperative bleeding and to enable further workup like CT scan and CT angiography to delineate the venous component.A multimodal approach was then taken for the excision of the tumour.
