Spinal schwannomatosis of the cauda equina in the absence of neurofibromatosis

Abstract

Schwannomatosis is a rare tumor syndrome characterized by the presence of multiple benign non-vestibular, non-intradermal schwannomas and by the absence of neurofibromatosis type 1 or 2 syndromes. Multiple schwannomas are clinically and genetically distinct from neurofibromatosis, and the main treatment in case of symptomatic lesions is represented by surgical resection. In case of asymptomatic lesions, the indicated treatment is neuroimaging follow-up (MRI). We are presenting the case of a patient with three schwannomas of the cauda equina, as well as the treatment strategy in the case of this rare pathology.
