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 کاملContext granulation and subjective-information quantification
In the course of comprehension, the human brain makes astounding inferences despite insufficient and ambiguous data—the data mostly being ‘words’ that frame sentences. Can this neural process of ‘‘abstraction of the relevant’’ be sufficiently modeled such that the computer may be induced to perform the same? This article is our response to this very question; a treatise on our attempt at engine...
متن کاملQuantification of lung surface area using computed tomography
OBJECTIVE To refine the CT prediction of emphysema by comparing histology and CT for specific regions of lung. To incorporate both regional lung density measured by CT and cluster analysis of low attenuation areas for comparison with histological measurement of surface area per unit lung volume. METHODS The histological surface area per unit lung volume was estimated for 140 samples taken fro...
