Patient Demographics and Clinical Features
Eight patients (2 female; 6 male) were identified with a median age of
13years (range 7.52-16.88years) at diagnosis. Pain was the presenting
symptom in all 8 patients and one patient also had lower extremity
weakness. All primary tumors were noted to be intradural and
predominantly in the lumbrosacral region of the spine, except one that
arose in the lower thoracic spine, involving the filum terminale or
adjacent to the tip of the conus medullaris (Fig.1.A-B). Three patients
had radiologically identified disseminated disease at presentation
(Fig.1.C-D).
