Interdural cavernous sinus dermoid cyst in a child: case report

Abstract

<jats:p>Interdural dermoid cysts (DCs) of the cavernous sinus (CS), located between the outer (dural) and inner layer (membranous) of the CS lateral wall, are rare lesions in children. The authors report on a 5-year-old boy with third cranial nerve palsy and exophthalmos who underwent gross-total removal of an interdural DC of the right CS via a frontotemporal approach. The patient had a good outcome and no recurrence at the 12-month follow-up. To the best of the authors' knowledge this is the second pediatric case of interdural DC described in the literature.</jats:p>

Infantile Dermoid Cyst in the Lateral Wall of the Cavernous Sinus: A Case Report and Literature Review

“… 8 , 10 , 13 , 19 – 21) To the best of our knowledge, there have only been two case reports of infantile interdural cavernous sinus dermoid cysts ( Table 1 ). 9 , 14) The lateral dural wall of the cavernous sinus is composed of two layers, the outer dural layer and inner membranous layer. 21) Tumors arising from components of the lateral dural wall are located between these two layers and are classified as interdural.…”

“… 7 – 20) Dermoid cysts localized in the lateral wall of the cavernous sinus are very rare and have only been reported in seven cases, including two infantile cases. 9 , 14) We herein present a case of an infantile dermoid cyst that occurred in the interdural space of the lateral wall of the cavernous sinus and clinical characteristics with a literature review.…”
