Management of asymptomatic cutaneous lumbosacral findings in newborns: a neurosurgical perspective.

The purpose of this study was to find areas of agreement among pediatric neurosurgeons with respect to the clinical management of asymptomatic newborns with a variety of lumbosacral skin findings. An electronic survey containing 18 clinical images and brief vignettes was sent to pediatric neurosurgeons within the American Academy of Pediatrics Section of Neurological Surgery (AAP SONS). In total, 38% (n = 21) of AAP SONS members submitted complete responses to the survey. Respondents were asked if they would advise routine care, watchful waiting, imaging, or subspecialty consultation for each clinical case. Responses were categorized into two groups: 1) watchful waiting and/or routine care, or 2) imaging and/or subspecialty consultation. Consensus was categorized as good (> 90% of responses in the same group), modest (70%-90%), and poor (< 70%). Demographic information, local factors impacting management, and experiences with local referral patterns were also collected. Among the pediatric neurosurgeons within the AAP SONS network, the authors found high levels (> 90%) of agreement that subcutaneous lipomas, faun tail nevi, large skin tags, and deep/atypical lumbosacral dimples in asymptomatic newborns should prompt an imaging study. Similarly, the authors found high agreement that simple coccygeal dimples do not need imaging. The management of some types of lumbosacral vascular marks and gluteal crease deviations had poor agreement (< 70%). When imaging was recommended, there was preference for spinal MRI in most cases (67%). Pediatric neurosurgeons generally agree that imaging of the spine is indicated for asymptomatic newborns with subcutaneous lipomas, faun tail nevi, large skin tags, or deep/atypical lumbar dimples (deep or atypical appearing). They also agree that imaging is unnecessary for infants with simple coccygeal dimples. There was a notable lack of consensus on the appropriate management of certain gluteal cleft deviations and cutaneous vascular marks.
