Abstract

Cerebrospinal fluid (CSF) leakage otorrhea may be congenital or can be caused by trauma, surgery, cholesteatoma, and tumors. Spontaneous CSF leakage through the middle ear without a secondary cause is a relatively rare disease. The pathophysiology of CSF otorrhea has not been clear yet. However, there are two theories of the pathophysiology of spontaneous CSF otorrhea have been studied in the medical field: one based on the congenital defect; the other about the arachnoid granulation which causes bone erosion. Herein, we examine and report a case of CSF otorrhea caused by arachnoid granulation. Literatures pertaining to the disorder will be reviewed and characteristics of the disorder also will be discussed.
