Case: A 17-year-old man was brought to our hospital by ambulance due to a severe headache and vomit. The meningeal irritation and right abducens nerve paralysis were found on neurologic examination. Head computed tomography (CT) revealed poor growth of the right mastoid pneumatization and a high absorption area in the sinus sagittalis superior from the right lateral venous sinus. On cerebral angiography, there was no depiction of the right sigmoid sinus, and thrombus was observed in sinus sagittalis superior. Therefore, it was diagnosed as cerebral venous sinus thrombosis. The cause of thrombosis was unknown a blood test. After admission the patient had right otorrhea. After examination, right otitis media cholesteatoma was found. Treatment was commenced with hypothesis thatotitis media cholesteatoma was involved as a cause of cerebral venous sinus thrombosis. Later, the symptoms resolved, and the patient was discharged. In cerebral venous sinus thrombosis, we should consider the possibility of otitis media cholesteatoma as a cause due to poor growth of the mastoid pneumatization as seen on head CT.
