“…We present a third case of prenatal diagnosis of CDS. Using PubMed search criteria of "prenatal dermal sinus," we were able to identify two other case reports of prenatal diagnosis of CDS [8,9]. A third article was found re-garding prenatal diagnosis of CDS; however, these authors do not consider this to be a true CDS given that the lesion connected the skin to an extracranial subcutaneous hemangioma instead of the spinal canal [10].…”

Introduction: Congenital dermal sinus (CDS) is an open neural tube defect (NTD) that occurs in 1 in 2500 births a year and often goes undetected until patients present with complications like infection and neurological deficits. Early diagnosis and repair of CDS may prevent formation of these complications. In utero diagnosis of these lesions may improve long-term outcomes by enabling referral to specialty services and planned postnatal repair, however only two such cases have been reported in the literature. We present a third case of in utero diagnosis of CDS with a description and discussion of findings from surgical exploration and pathology. Case Presentation: Routine prenatal ultrasound scan detected a tethered cystic structure arising from the back of the fetus at 20 weeks gestation. Dedicated fetal ultrasound confirmed the presence of a cystic lesion protruding through a lamina defect while fetal magnetic resonance imaging (MRI) showed an intact spinal cord and meninges, suggesting a diagnosis of CDS. Neurosurgery followed along closely and took the child for surgical exploration on day 2 of life. A fibrous stalk with an intradural component and associated cord tethering was excised. Histology showed fibrous tissue without an epithelial-lined lumen. Conclusion: CDS is a form of NTD that occurs from nondisjunction of the cutaneous ectoderm and neuroectoderm during formation of the neural tube. Slight differences in how this error occurs can explain variations seen in this spectrum of disease, including CDS without an epithelial-lined lumen as seen in this case. Newborns with CDS can go undiagnosed for years and present with long-term complications. Fetal imaging can assist in early recognition and surgical excision of CDS in newborns.

“…Concerning the origin, the wide accepted theory proposes that the origin of all SCMs originated from one basic ontogenic error occurring around the time of closure of the primitive neurenteric canal. A formation of an accessory neurenteric canal which is considered as an abnormal fistula causes regional splitting of the notochord and the overlying neural plate [7][8][9][10]. The location of this abnormality is highly variable, having the lumbar region being the most common (51.9%) and the cervical and sacral regions being the rarest (0.9%).…”

“…The literature shows numerous cases of SCM diagnosed in the prenatal period by means of ultrasound and confirmed by MRI [ 4 , 8 , 9 ]. Majority of patients are under the age of 7; however, the oldest reported case of SCM was for a 78-year-old lady [ 3 ].…”

Split cord malformation (SCM), a subtype of spinal dysraphism, represents a rare entity of congenital malformation in the spine that occurs rarely in adults. SCM commonly presents with back pain. MRI is the gold standard for diagnosis. We report a case of a previously healthy 25-year-old woman who presented with lower back pain for a duration of 6 months. MRI confirmed a diagnosis of type I SCM. This case highlights the neuroimaging characteristics of SCM, although it might remain asymptomatic for many years. Surgical intervention might not be indicated in case of absent clinical complications.
