Congenital pterional dermal sinus in an 18-month-old child: case report
1Department of Neurological Surgery, Columbia University, New York, New York 10032, USA.
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.
