ObjectiveTo discuss the CT manifestation and clinical significance of rare neoplasm in maxillary sinus, includingmalignant myoepithelioma, angioendothelioma, sarcoma of plasmacyte.
Alternatively, initially perform a TEE, and if no thrombus is present, cardiovert and therapeutically anticoagulate for a minimum of 4-6 weeks after sinus rhythm is restored.
Methods Suturing of dural laceration with 2-0 or 3-0 woundless silk thread was performed in twenty-two cases of intracranial venous sinus injuries produced by variant causes.
Results MRI appearances of painful ophthalmoplegia syndrome included patch or small nodule abnormal signal at the region of fissura orbitalis superior. The ipsilateral cavernous sinus was enlarged.
The uncinate fragment is then grasped and removed as one piece.This should bring into view the opening of the maxillary sinus and facilitate subsequent maxillary sinus meatotomy.
Results We learn that coronal CT with assistant horizontal CT scan can make a very clear display about subtie structure of Paranasal sinus, lesion area and extent.
RESULTS The CTfeathures of ossifying fibroma inparanasal sinus were similar torotundity or unregular single high density lump in sinus, partarea of low density, integrity bone involucrum around it.
Isochrones were displayed both during sinus rhythm and AF.Results During sinus rhythm,the atrial excitation wave front begins from sinus node spreading to right atrium(RA)and left atrium(LA).
