Dermal sinus tract of the spine

Abstract

Dermal sinus tract is an innocuous-appearing spinal dysraphism that may contribute to devastating morbidities if not timely addressed. In order to prevent complications, timely surgical intervention including complete resection of sinus tract with intradural exploration and correction of associated abnormalities is of utmost importance.

Lateral Buttock Congenital Dermal Sinus Tract -Case Report-

“…CDS typically appears as a low intensity tract that ascends in the subcutaneous tissue with high intensity on both T 1 -and T 2 -weighted images. 1,5,8) This modality is especially useful for detecting low-placed conus and associated anomalies such as inclusion tumors or split cord malformations. 8) However, MR imaging may not clearly demonstrate small tracts, especially in a neonate or with a deviated course like our case.…”

“…1,5,8) This modality is especially useful for detecting low-placed conus and associated anomalies such as inclusion tumors or split cord malformations. 8) However, MR imaging may not clearly demonstrate small tracts, especially in a neonate or with a deviated course like our case. 5) Only 40% of tracts were detected in the preoperative MR images.…”

“…The etiology of dermal sinus, which is speculated to be persistent cutaneous ectoderm in the subcutaneous layer, is generally accepted as separation failure between the neuro-and cutaneous ectoderm. 1,8) The dimples above the gluteal cleft are considered to be derived from midline disjunction of the primary neurulation and the tract will ascend subcutaneously. 5) In contrast, dimples in the gluteal cleft and lower sacral segment are thought to be derived from secondary neurulation and the tract will not ascend but ends beside the fascia along the lower sacral spine.…”

“…5,8) The sinus ostium is located in the midline of the posterior of the body from the occiput to the lumbosacral region, but most cases of CDS are found between the lumbar and sacral spine. Patients with CDS can present with skin findings, infection, and space-occupying lesions caused by inclusion tumors such as dermoid, epidermoid, and tethered cord syndrome.…”

Spinal dermal sinus tract

“…Dear Editor, We read with great interest the recent article by Radmanesh et al [1] concerning spinal dermal sinus tract (DST) in children. The authors studied 35 children with this rare congenital dysraphism.…”
