MR evaluation of spinal dermal sinus tracts in children.
The MR studies of seven pediatric patients with surgically proved spinal dorsal dermal sinuses were reviewed retrospectively. Five of the seven had associated congenital tumors (three epidermoids, two dermoids). The subcutaneous portions of the spinal tracts and intramedullary portions of tumor were easily identified with the use of standard spin-echo techniques. However, except for limited are...
متن کاملBilateral retro-auricular dermal sinus tracts with intradural extension. Case report.
The authors describe a previously unreported malformation involving paired, bilaterally symmetrical dermal sinus tracts in the retro-auricular area, both of which passed through the asterion and posterior fossa dura mater to end intracranially. Cranial dermal sinus tracts are congenital lesions that virtually always originate from the midline scalp posteriorly at the external occipital protuber...
متن کاملCutaneous sinus tracts (or emerging sinus tracts) of odontogenic origin: a report of 3 cases
Three cases are presented in which patients presented with either cutaneous swelling or cutaneous sinus tracts of odontogenic origin. A cutaneous sinus tract of odontogenic origin is a pathway through the alveolar bone that typically begins at the apex of an infected tooth or of an infected portion of the dental alveolus and empties infected material (pus) through the skin. Where as the more co...

متن کاملCongenital dermal sinus.
congenital dermal sinus tract is an uncommon type of spinal dysraphism that results when a focal area of the ectoderm fails to separate from the underlying neuroectoderm, a process termed nondysjunction. Nondysjunction prevents the insertion and subsequent development of mesodermal tissue, which normally separates the spinal cord from the skin. Congenital dermal sinus tracts occur rarely and ar...
