    ObjectiveIn patients with new primary intradural spinal tumors, the best screening strategy for additional central nervous system (CNS) lesions is unclear. The goal of this study was to document the rate of additional CNS tumors in these patients.MethodsAdults with primary intradural spinal tumors were retrospectively reviewed. Imaging strategy at diagnosis was classified as focused spine (cervical, thoracic, or lumbar), total spine, or complete neuraxis (brain and total spine). Tumor pathology, genetic syndromes, and presence of additional CNS lesions at diagnosis or follow-up were collected.ResultsThe study comprised 319 patients with mean age of 51 years and mean follow-up of 41 months. In 151 patients with focused spine imaging, 3 (2.0%) were found to have new lesions with 2 (1.4%) requiring treatment. In 35 patients with total spine imaging, there were no additional lesions. In 133 patients with complete neuraxis imaging, 4 (3.0%) were found to have new lesions with 2 (1.5%) requiring treatment. There was no difference in the identification of new lesions (P = 0.542) or new lesions requiring treatment (P = 0.772) across imaging strategies. Among patients without genetic syndromes, rates of new lesions requiring treatment were 1.4% for focused spine, 0% for total spine, and 2.2% for complete neuraxis (P = 0.683). There were no cases of delayed identification causing risk to life or neurological function. Complete neuraxis imaging carried an increased charge of $4420 per patient.ConclusionsAmong patients without an underlying genetic syndrome, the likelihood of identifying additional CNS lesions requiring treatment is low. In appropriate cases, focused spine imaging may be a more cost-effective strategy.Copyright © 2020 Elsevier Inc. All rights reserved.
