Papilledema secondary to parietal dermoid - epidermoid cyst with superior sagittal sinus compression

Áine Ní Mhéalóid, We Fong Siah


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.
