INTRODUCTION: Epidermoid cysts within the sylvian fissure are extremely rare. Expressive aphasia and neurocognitive dysfunction because of mass effect have never been reported previously.
CASE PRESENTATION: We discuss the case of a 53-year-old male who presented with an acute episode of expressive aphasia and vision changes along with progressive headaches and cognitive slowing over the 2.5 years prior to presentation. A detailed neurologic examination revealed subtle conductive aphasia, as well as mild short-term memory dysfunction. Magnetic resonance imaging revealed a cystic mass consistent with epidermoid cyst within the left sylvian fissure. High-definition fiber tractography showed that the arcuate fasciculus was stretched by the tumor. A left frontotemporal craniotomy allowed for near-total excision of the cyst and led to rapid and complete resolution of symptoms.
CONCLUSION: Although rare, epidermoid cysts of the dominant sylvian fissure can present with progressive aphasia due to mass effect on the arcuate fasciculus. Despite the long-standing symptoms, surgical resection can lead to their complete resolution.
