Abstract:
We report the case of a female patient who consulted to the Room Emergencies due to abundant watery otorrea of 3 months without another symptom or apparent cause. The studys confirmed the presence of cerebrospinal fluid (CSF) and the imaging tests (CT and MRI) demonstrated the existence of a communication between the right ear and middle cerebral fossa through tegmen timpani. The woman was operated by ORL (closing the fistula) and neurosurgery (placing an external lumbar drainage) with good postsurgical evolution.
