Congenital Dermal Sinus

<b><i>Introduction:</i></b> The embryogenesis of limited dorsal myeloschisis (LDM) likely involves impaired disjunction between the cutaneous and neural ectoderms during primary neurulation. Because LDM and congenital dermal sinus (CDS) have a shared origin in this regard, CDS elements can be found in the LDM stalk. Retained medullary cord (RMC) is a closed spinal dysraphism involving a robust, elongated, cord-like structure extending from the conus medullaris to the dural cul-de-sac. Because the RMC is assumed to be caused by impaired secondary neurulation, concurrent RMC and CDS cannot be explained embryologically. In the present article, we report a case in which CDS elements were noted in each tethering stalk of a coexisting LDM and RMC. <b><i>Case Presentation:</i></b> A 2.5-month-old boy with left clubfoot and frequent urinary and fecal leakage had 2 tethering tracts. The upper tract, which ran from the thoracic tail-like cutaneous appendage, had CDS elements in the extradural stalk and a tiny dermoid cyst in the intradural stalk immediately after the dural entry. In the lower tract, which ran from the lumbosacral dimple, the CDS as an extradural stalk continued to the RMC at the dural cul-de-sac. Both stalks were entirely resected through skip laminotomy/laminectomy at 1 stage to untether the cord and resect the CDS elements. <b><i>Conclusion:</i></b> Surgeons should be aware that CDS elements, in addition to LDM, may coexist with RMC that extends out to the extradural space.

Abstract Dermoid cysts are space-occupying tumors that can occur anywhere in the neuroaxis. Although categorized as benign lesions, they can compromise normal structures, causing neurological function loss, and have a tendency to recur often requiring repeated surgical resections. We illustrate the case of an extensive epidural dermoid cyst in a 22-yr-old woman who presented with progressive loss of neurological motor function in her lower extremities as well as bowel and bladder incontinence. The tumor extended from T10 to the sacrum, and a conventional operation would have entailed serial laminectomies that would cross the thoracolumbar and lumbosacral junctions, possibly requiring an instrumented fusion. Given the fact that operation would have carried significant morbidity, especially with the high likelihood of symptomatic tumoral recurrence, we consulted with our urology colleagues to find a minimally invasive way of reducing the tumor burden and decompressing the neural elements. The patient was taken to the operating room and a limited open lumbosacral durotomy was performed. A flexible cystoscope was then passed in the epidural space and used to suction the tumor. Postoperative imaging showed adequate resection, and the patient recovered neurological function completely. She had mini-mal recurrence at 3 yr and remained asymptomatic. This technical video note showcases the potential for use of endoscopy for spine tumors that have an amenable consistency, even in highly eloquent areas such as the conus medullaris. It also serves to highlight the benefits of interdisciplinary cooperation when treating complex disease. This case report was written in compliance with our institutional ethical review board. Institutional Review Board (IRB) approval and patient consent was waived in light of the retrospective and deidentified nature of the data presented in accordance with the University of Texas SouthWestern IRB.

Abstract Prevotella species are gram-negative anaerobic commensal bacteria of the oropharynx, which frequently cause periodontal disease but are otherwise rarely implicated in serious bacterial infections. Cranial dermoid cysts are benign neoplasms that grow along the planes of the embryonic neural tube closure. In infants, they most commonly present in frontal locations, including periorbital, nasal, and within the anterior fontanelle. Although dermoid cysts are slow growing, usually uncomplicated, and easily treated definitively with surgical excision, cranial cysts located on the midline are associated with a higher risk for persistent dermal sinus tract with intracranial extension of the tumor. We describe a case of a 10-month-old male patient with an occipital midline dermoid cyst with intracranial extension, infected with Prevotella melaninogenica, and complicated by intracranial abscess formation and meningitis.This case highlights two unusual disease entities: the uncommon occipital location of a dermoid cyst, and complications of that cyst caused by a serious bacterial infection with a normal oral flora. We discuss the recommendation for neuroimaging prior to surgical excision of a midline dermoid cyst, given the risk for dermal sinus tract with intracranial communication. We also discuss potential mechanisms for bacterial inoculation of this cyst with Prevotella melaninogenica. This pathogen has not previously been reported as a complication of dermoid cysts.
