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.

✓ The clinical course of 12 patients who underwent terminal ventriculostomy for syringomyelia is presented. Opening the central canal at the tip of the conus medullaris is a relatively benign procedure that improves the symptoms of syringomyelia and syringobulbia. This canal normally terminates at the tip of the conus, but in each of the 12 surgical specimens it continued into the filum terminale for distances up to 8 cm. In most cases the tip of the conus was located more caudally than normal, indicating some degree of tethering in fetal life. This belief is supported by the fact that the newborn, whose conus is tethered to a lipoma at the sacral level, may develop syringomyelia in adult life.

✓ The case of a 73-year-old woman found to have hydrosyringomyelia associated with a lower thoracic meningioma is reported. Possible mechanisms for the formation of the hydrosyrinx are discussed, with particular attention being paid to the possibility of transmural passage of cerebrospinal fluid into the central canal.

Intramedullary Dermoid Cyst

OBJECT Intramedullary dermoid cysts are rare tumors of the spinal cord. Presentation with rapid onset of paraparesis or quadriparesis (onset within 2 weeks) is rarer still. The authors present their experience in the management and outcome of patients with such a presentation. METHODS Patient records between 2000 and 2014 were retrospectively reviewed to identify those with intraspinal dermoid cysts who presented with rapid-onset paraparesis or quadriparesis. Their clinical, radiological, operative, and follow-up data were analyzed. RESULTS Of a total of 50 patients with intraspinal dermoid cysts managed during the study period, 10 (20%) presented with rapid-onset paraparesis or quadriparesis; 9 patients ranged in age from 8 months to 2 years, and 1 patient was 25 years old. A dermal sinus was seen in the lumbar region of 4 patients, the sacral region of 3, and the thoracic region of 1, and in 1 patient no sinus was found. All except 1 patient presented with rapid-onset paraparesis secondary to infection of the intramedullary dermoid cyst. One patient presented with rupture of a dermoid cyst with extension into the central canal up to the medulla. Early surgery was done soon after presentation in all except 2 patients. Among the 9 patients who underwent surgery (1 patient did not undergo surgery), total excision of the intramedullary dermoid cyst was done in 3 patients, near-total excision in 4 patients, and partial excision in 2 patients. Of the 9 patients who underwent surgery, 8 showed significant improvement in their neurological status, and 1 patient remained stable. The 1 patient who did not undergo surgery died as a result of an uncontrolled infection after being discharged to a local facility for management of wound infection. CONCLUSIONS Early recognition of a dermal sinus and the associated intraspinal dermoid cyst and timely surgical intervention can eliminate the chances of acute deterioration of neurological function. Even after an acute onset of paraparesis or quadriparesis, appropriate antibiotic therapy and prompt surgery can provide reasonably good outcomes in these patients.

Histological Characteristics

✓The ventriculus terminalis (VT) is a small ependyma-lined cavity within the conus medullaris that is in direct continuity with the central canal of the anterior portion of the spinal cord. Normally, such a cavity is identifiable only histologically in children and adults and can be visualized using common neuroradiological techniques only after dilation. Currently, the mechanisms of isolated dilation are not documented. The present work describes 2 cases of VT in elderly patients. Data from a histological and ultrastructural study of a case of VT dilation are reported, and the results are compared with those obtained from the VT of 5 fetuses to explain the nosological aspects of nontumoral VT lesions. Our data suggest that the site, age, and histological characteristics of the lesion allow us to define VT dilation as a nosological entity distinct from other cystic dilations of the conus medullaris.
