Sinus and Fistula |

Abnormal opacification of paranasal sinuses on brain MRI was studied in 178 consecutive adult patients who underwent two examinations separated by at least 4 months because of suspected neurological disease. Sinus abnormality was present in 79 (44%) patients; in 60% the abnormality involved two or more sinuses and it was bilateral in 51%. The most frequently abnormal sinus was the maxillary (46%), followed by the ethmoid (32%), sphenoid (16%), and frontal sinuses (6%). Interval occurrence or complete resolution of abnormalities was observed in 52% of patients (66% of the sinuses). In the remaining 48% of patients the abnormalities were present on two or more examinations, unchanged or of increased or decreased severity. The most frequent interval changing abnormalities were complete sinus opacification and fluid levels, followed by irregular mucoperiosteal thickening more than 4 mm thick. No polypoid abnormalities (polyps or mucosal cysts) decreased over time. (1)-Sinus:The sinuses are a connected system of hollow cavities in the skull. The largest sinus cavities are about an inch across. Others are much smaller. Your cheekbones hold your maxillary sinuses (the largest). The low-center of your forehead is where your frontal sinuses are located (2)-Fistula:A fistula is an abnormal connection between two body parts, such as an organ or blood vessel and another structure. Fistulas are usually the result of an injury or surgery.
