Abstract
Occult Spinal Dysraphism with Dermal Sinus and Filum Terminale Lipoma – Case Report
The purpose of this report is to describe the case of a pediatric patient with occult spinal dysraphism associated with filum terminale lipoma and dermal sinus — conditions resulting from failures in neural tube closure during embryonic development, without exposure of neural tissue. Although there were no initial neurological symptoms, the presence of cutaneous stigmata in the lumbosacral region led to investigation by magnetic resonance imaging (MRI), which revealed a low-lying conus medullaris (L3–L4). The patient underwent surgery to release the filum terminale and remove the dermal sinus, aiming to prevent acute neurological complications such as central nervous system infection and progressive ones like tethered cord syndrome.
