Cerebrospinal fluid rhinorrhoea secondary to amyloidosis of the sphenoid sinus.
Amyloidosis of the skull base is a rare entity. A patient with localized amyloidosis of the sphenoid sinus presented at our institution with cerebrospinal fluid rhinorrhoea. Endoscopic excision of the lesion and multilayered obliteration of the sphenoid sinus resolved the symptoms.
متن کاملMULTI PHASE COMPUTATIONAL FLUID DYNAMICS MODELING OF CAVITATING FLOWS OVER AXISYMMETRIC HEAD-FORMS
In the present paper, partial cavitation over various head-forms was studied numerically to predict the shape of the cavity. Navier-Stokes equations in addition to an advection equation for vapor volume fraction were solved. Mass transfer between the phases was modeled by a sink term in vapor equation in the numerical analysis for different geometries in wide range of cavitation numbers. The r...
متن کاملTreatment strategies for lateral sphenoid sinus recess cerebrospinal fluid leaks.
OBJECTIVE To highlight concepts critical to achieving successful repair and avoiding intracranial complications in the treatment of cerebrospinal fluid (CSF) leaks from the lateral recess of the sphenoid sinus (LRS). DESIGN Outcomes study. SETTING Tertiary referral university hospital. PATIENTS Eleven patients with LRS CSF leaks from June 2008 to June 2010. INTERVENTIONS Endoscopic tran...
متن کاملIrrigation Nose: CT Findings of Paranasal Sinus Exostoses
We report the case of a 57-year-old male who presented with recurrent sinus infections and frequent nasal irrigation. He was found at nasal endoscopy to have multiple outgrowths along his ethmoid and maxillary sinuses. Computed tomography (CT) showed multiple bony exostoses along these sinuses. We report the imaging findings of exostoses associated with sinonasal irrigation.
متن کامل2D Computational Fluid Dynamic Modeling of Human Ventricle System Based on Fluid-Solid Interaction and Pulsatile Flow
Many diseases are related to cerebrospinal .uid (CSF) hydrodynamics. Therefore, understanding the hydrodynamics of CSF .ow and intracranial pressure is helpful for obtaining deeper knowledge of pathological processes and providing better treatments. Furthermore, engineering a reliable computational method is promising approach for fabricating in vitro models which is essential for inventing gen...
