Cerebrospinal Fluid Otorrhea Caused by Arachnoid Granulation
نویسندگان
چکیده
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.

Repair of Spontaneous Cerebrospinal Fluid Otorrhea from Defect of Middle Cranial Fossa
Spontaneous cerebrospinal fluid (CSF) otorrhea is defined as CSF otorrhea where there are no identifiable causes including previous trauma, surgery, infection, neoplasm or congenital anomaly. The condition is rare. The origin of CSF leak is commonly a defect in the tegmen of the middle cranial fossa. The pathophysiology of spontaneous CSF otorrhea is unclear. Two theories of the etiology of bon...
متن کاملRepair of Tegmen Tympani Defect Presenting with Spontaneous Cerebrospinal Fluid Otorrhea Using the Middle Cranial Fossa Approach.
Spontaneous cerebrospinal fluid (CSF) otorrhea frequently occurs without temporal bone trauma, fracture, surgery, or any identifiable causes. It is usually associated with tegmen tympani defects of the temporal bone in adults. The congenital origin theory and the arachnoid granulation theory have been accepted to explain the tegmen tympani defect. Magnetic resonance imaging (MRI) and computed t...
متن کاملBrain Herniation into Giant Arachnoid Granulation: An Unusual Case
Arachnoid granulations are structures filled with cerebrospinal fluid (CSF) that extend into the venous sinuses through openings in the dura mater and allow the drainage of CSF from subarachnoid space into venous system. Usually they are asymptomatic but can be symptomatic when large enough to cause sinus occlusion. We report a rare case of a brain herniation into a giant arachnoid granulation ...
متن کاملArachnoid granulations may control heat exchange between intracranial dural sinuses and cerebrospinal fluid
Selective brain cooling is a system in a human that protects the brain from hyperthermia. Cool venous blood from head skin and upper respiratory tract drains into intracranial dural sinuses. In that region, cool blood in the dural sinuses decreases the temperature of the cerebrospinal fluid. Cerebrospinal fluid provides brain cooling. All cortical arteries to the brain pass the cerebrospinal fl...
