This retrospective study reports on sinus abnormalities detected in patients having magnetic resonance imaging (MRI) scans. Over a 12-month period, 1120 patients (aged 2-87 years) had MRI scans done for suspected intracranial pathology. Scans were reviewed independently for abnormal sinuses using four criteria: increased signal of the epithelial lining, cloudy or opacified sinus cavity, air-fluid levels, and intrasinus polyps. Thirteen percent of the 1120 patients had abnormal sinus images with the maxillary being the most involved cavity. A cloudy or opacified sinus was found in 43% of these cases. An increased signal to the epithelial lining was present in 44%. Intrasinus polyps were found in 27 paranasal sinus cavities (27 subjects). Furthermore, a seasonal pattern was evident for abnormal sinus scans. The months of July, August, September, and December had the highest frequency of abnormalities noted (greater than 16% of total scans done) whereas there was a low percentage (less than 8%) found during February and November. In summary, abnormalities of the paranasal sinuses occur frequently and vary with the time of year.
这项回顾性研究报告了在接受磁共振成像（MRI）扫描的患者中检测到的鼻窦异常情况。在12个月的时间里，1120名患者（年龄在2至87岁之间）因疑似颅内病变接受了MRI扫描。使用以下四个标准对扫描结果进行独立审查，以确定鼻窦是否异常：上皮衬里信号增强、鼻窦腔混浊或不透明、气液平面以及鼻窦内息肉。在这1120名患者中，13%的患者鼻窦图像异常，其中上颌窦是受累最严重的鼻窦腔。在这些病例中，43%发现鼻窦腔混浊或不透明。44%存在上皮衬里信号增强。在27个鼻窦腔（27名受试者）中发现了鼻窦内息肉。此外，鼻窦异常扫描呈现出明显的季节性模式。7月、8月、9月和12月的异常频率最高（占总扫描量的16%以上），而2月和11月的异常比例较低（不到8%）。总之，鼻窦异常情况频繁发生，且随一年中的时间而变化。
