 - Abstract: PURPOSE: To investigate the prevalence of occult spinal dysraphism (OSD) and subsequent neurosurgery in pediatric patients with isolated or combined dorsal midline cutaneous stigmata with or without other congenital malformations. METHODS: We carried out a retrospective review of patients who underwent sonography or magnetic resonance imaging (MRI) for OSD because of suspicion of dorsal midline cutaneous stigmata (presumed to be a marker for OSD) between January 2012 and June 2017. Information about patient characteristics, physical examination findings, spinal ultrasound and MRI results, neurosurgical notes, and accompanying congenital anomalies was collected. RESULTS: Totally 250 patients (249 ultrasound and one MRI screening) were enrolled for analysis. Eleven patients underwent secondary MRI examinations. The prevalence of OSD confirmed by an MRI was 2.4% (6 patients including one MRI screening). Five patients (2%) had tethered cord and underwent prophylactic neurosurgery, 3 of whom had a sacrococcygeal dimple and a fibrofatty mass. Prevalence of tethered cord increased as markers associated with a sacrococcygeal dimple increased (0.5% of the isolated marker group, 8.1% of the 2-marker group, and 50% of the 3-marker group). Incidence of OSD with surgical detethering in 17 other congenital anomaly patients was 11.8%, which was higher than the 1.3% in 233 patients without other congenital anomalies. CONCLUSION: Our results suggest that the presence of dorsal midline cutaneous stigmata, particularly fibrofatty masses, along with a sacrococcygeal dimple is associated with OSD or cord tethering requiring surgery. OSD should be suspected in patients with concurrent occurrence of other congenital anomalies.
