Cerebrospinal Fluid Otorrhea Caused by Arachnoid Granulation
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 m...
متن کاملGiant arachnoid granulation mimicking dural sinus thrombosis
Arachnoid granulations (AG) are composed of dense, collagenous connective tissue that includes clusters of arachnoid cells. They tend to invaginate into the dural sinuses, through which cerebrospinal fluid enters the venous system. AG are most commonly seen at the junction between the middle and lateral thirds of the transverse sinuses near the entry sites of the superficial veins. Presently de...
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 کاملGiant Arachnoid Granulation Associated with Anomalous Draining Vein: A Case Report
Giant arachnoid granulations (AG) can mimic intracranial lesions. Knowledge of these structures can help avoid misdiagnosis when interpreting imaging. Here, we report a child who presented with a mass within the superior sagittal sinus and an anomalous draining vein. Herein, the diagnosis of a giant AG was made. Clinicians who view or interpret imaging of the head should be aware of these anato...
متن کاملA preliminary anatomical study on carotid body of Makouei sheep
The carotid is a small mass of chemoreceptor's and sustentacular cells that detects changes in the composition of the arterial blood. The aim of the present study was to identify the size, color, location, blood and nerve supply of the carotid body in Makouei sheep. Fourteen heads of sheep from both sexes were collected from Urmia public slaughter-house. The exact situation and nerve supply of ...
