Congenital Dermal Sinus

Ten patients are presented in whom intracranial extension of a congenital dermal sinus was disclosed by operation. The complications of this lesion include infection in the form of meningitis, abscess formation and osteomyelitis as well as hydrocephalus due to obstruction of the spinal fluid pathways. In unexplained meningitis, the entire midline area of skin over the neural axis should be examined carefully for evidence of a dermal sinus opening. Whenever a dimple or subcutaneous mass is found in the midline of the scalp, RGs should be examined carefully for an underlying skull defect. When such a defect exists, intracranial exploration is indicated. Surgical treatment previous to development of intracranial infection is relatively simple and should be rewarded by complete cure. Excision after infection has occurred is difficult and the results in this group have been poor.

Histopathologic Analysis

Introduction. Intracranial extension is rarely seen with craniofacial dermoid cysts, with few cases reported in the literature. Case Outline. We report a case of a 30-year-old woman who was initially seen with a subcutaneous mass of the frontotemporal region. The patient underwent a right craniotomy by a frontal approach. Histopathologic analysis confirmed the diagnosis of a dermoid cyst. Conclusion. Craniofacial dermoid cysts may be associated with an intracranial extension.

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.

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.

Symptoms And Signs

This case is related to a 52-year-old lady with proptosis, diplopia and diminution of vision due to a mass lesion in upper medial quadrant of the orbit. CT scan revealed a well defined mass in basi-frontal area with intra-orbital and intracranial extension. On exploring it was found to be mucopyocele of the frontal sinus. Surgical excision was done by external approach. The symptoms and signs resolved completely within a week. Frontal sinus mucopyoceles are benign and curable. Early recognition and management of them is of paramount importance because they can expand and cause local, orbital or intracranial complications.

Congenital Dermal Sinus

Abstract OBJECTIVE Congenital dermal sinus tracts most frequently occur in the midline and are often associated with dermoid or epidermoid inclusion cysts. A lateral cranial origin is extremely rare and anatomically inconsistent with an etiology involving closure of the rostral neural tube during embryogenesis. CLINICAL PRESENTATION We describe the first case of a pterional cranial dermal sinus tract associated with a small epidermoid, with extension to the dura of the anterior cranial fossa. INTERVENTION The extra- and intracranial portions of the tract were visualized and resected with the use of an operating microscope. Pathological diagnosis confirmed dermal sinus tract. CONCLUSION We review the existing literature and address the developmental and clinical features pertinent to the management of cranial dermal sinus tracts, emphasizing the need for exploration of these potentially harmful lesions.

There is ample evidence to indicate that administration of antimicrobial therapy alone to patients with intracranial abscess can result in neurologic deterioration1 and higher mortality.2 In our article entitled "Complications of Sinusitis in Children" we described the occurrence of intracranial complications following sinusitis.3 Surgical drainage accompanied by antimicrobial therapy resulted, eventually, in complete cure of all of our patients. However, three out of four of our patients with intracranial abscess initially did not respond to appropriate antimicrobial therapy directed against the organisms recovered from their abscesses.
