BACKGROUND: A considerable number of @entity1 suffer delayed @entity51 even after a successful removal of @entity4097 . The underlying pathology remains unknown. Radiological findings could be an explanation for poor outcome after surgery. METHODS: We conducted a retrospective study of all cases treated from 1980 to 2016 in our department. Included were all @entity1 with @entity4097 treated with microsurgical excision. The cross-sectional area (CSA) of the spinal cord at the level of the former performed surgery was compared in MRI scans with follow up MRI scans, adjacent not affected levels and with control group. RESULTS: 54 @entity1 with an intramedullary spinal cord lesion were treated in this period. @entity424 was the predominant @entity5 (28) followed by @entity11 and @entity455 . Mean age was 48.2    10.5 years with a female predominance (f=16, m=12). An unfavorable outcome was observed in 53% of the @entity1 after an initially uneventful postoperative course. The follow up cross-sectional area of the spinal cord was significantly reduced in these @entity1 compared to adjacent not operated levels and control group. Sagittal and axial spinal MRI showed spinal cord narrowing due to @entity3202 in the area of the performed surgery in 53 % of @entity1 with @entity424 after a mean follow-up time of 9 years. Functional outcome in @entity424 was significantly associated with @entity602 (p< 0.05). CONCLUSIONS: @entity602 seems to be a predicting factor in long term outcome after surgical removal of @entity4097 .

Regional XXXX is associated with poor outcome after surgery on @entity4097 : a new aspect of delayed neurological deterioration.
