Dermoid and epidermoid cysts are benign slow growing tumors that arise from ectodermal tissue.  In this case report, a 32-year-old gentleman presented with a right posterior parietal dermoid - epidermoid cysts resulting in superior sagittal sinus compression.  Clinical examination disclosed enlarged blindspot formation in both eyes and bilateral papilledema.  He was treated with a low-pressure shunt, resulting in resolution of the papilledema and his symptoms.  In a search of the peer-reviewed medical literature (using MEDLINE and cross-referenced literature), this report may be the second to report papilledema secondary to an intracranial dermoid or epidermoid cyst with superior sagittal sinus compression.
