FRONTONASAL EPIDERMOID CYST WITH PATENT DERMAL SINUS TRACT OPENING ON THE DORSUM OF NOSE AND INTRACRANIAL EXTENSION THROUGH CRIBRIFORM PLATE DEFECT: A RARE CASE REPORT WITH REVIEW OF LITERATURE

Congenital midface anomalies are rare. Multiple congenital midface anomalies occur in children. Imaging techniques like computed tomography (CT) and magnetic resonance imaging (MRI) help in characterising the lesions, making definite diagnosis and knowing about intracranial extension. We present a case report of 8 year old female child with Frontonasal Epidermoid Cyst with patent dermal sinus tract opening on the dorsum of nose and intracranial extension through cribriform plate defect.

Spinal epidermoid cyst is a rare entity. It may be congenital with associated spinal dysraphism such asspina bifida ,dermal sinus tract and other neural tube defects or acquired due to repeated lumbar puncture and trauma. Congenital spinal epidermoid cysts without spinal dysraphism are rare. Here we are reporting a rare and interesting case of thoracic extramedullary intradural epidermoid cyst with no associated features of spinal dysraphism or history of iatrogenic trauma in a young male patient.

Dermal Sinus Tract

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.

Epidermoid Inclusion Cyst

Abstract A 30-month-old Mexican girl with an inclusion subgaleal cyst located over the anterior fontanel is described. This is the first such case ever diagnosed at our institution and, we believe, the first reported from Mexico. Radical excision of the lesion was accomplished. The internal table of the skull was eroded, but no intracranial extension was noticed. As the cyst contained no hair follicles nor any sebaceous or sweat glands, it was histologically classified as an epidermoid cyst. This is another example of such a lesion in an infant of non-African descent.

We report the use of diffusion-weighted magnetic resonance imaging to diagnose and manage a rare case of a symptomatic thoracic intramedullary congenital epidermoid cyst with associated dermal sinus in a girl. Congenital intramedullary epidermoid cysts with associated dermal sinuses are very rare occurrences and seldom present symptomatically in very young children. We present a case of a 32-month old with a draining dimpled skin lesion. Magnetic resonance images demonstrated an intramedullary epidermoid with a dorsal dermal sinus tract opening to the skin surface which was confirmed surgically. The patient was treated with debulking to prevent recurrent infection and progression of neurological symptoms. This case demonstrates the use of diffuse-weighted MRI to assist in the diagnosis and surgical management of an atypical presentation of a rare developmental abnormality, which is not well documented in the pediatric radiological literature. Failure to diagnosis may have significant neurological permanent debilitating consequences.

Fine Print

✓ 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 protuberance, anteriorly at the nasion or along the nasal dorsum, or in the posterior parietal midline. A lateral origin is extremely rare, and intracranial extension of a lateral dermal sinus tract has not been reported previously. The authors propose an embryological mechanism to explain the origin of this rare malformation and discuss its management.
