Interdural epidermoid of the cavernous sinus.

Ghaemi K et al. Interdural Epidermoid Tumor ... Cen Eur Neurosurg 2010; 71: 155 – 156 Introduction & Epidermoids account for 0.3 – 1.8 % of all intracranial space-occupying lesions [4, 6, 18] . Most of these tumors are located in the cerebellopontine angle, but they may occur at any site within the cranial cavity [15] . Rarely, they may be found in the cavernous sinus, and an unusual variant is occurrence within the lateral dural layers of the cavernous sinus [2, 6] . To the best of our knowledge, the isolated manifestation of an oculomotor palsy has not been reported previously in this context. Here we report on the management and the postoperative course after removal of an epidermoid between the dural layers of the lateral wall of the cavernous sinus.
