目的:探讨CT、MRI对霉菌性鼻窦炎的诊断和鉴别诊断价值。方法:回顾性分析32例霉菌性鼻窦炎CT、MRI表现。结果:霉菌性鼻窦炎的CT表现主要为:①90.6%的病变内有高密度钙化影。大多呈斑点状,位于窦腔中央,与窦壁无关。②50.0%的窦壁存在骨质破坏,常见于上颌窦内侧壁,其特点是伴有窦壁骨质增生。霉菌性鼻窦炎的MRI表现为上颌窦病变中央大部分呈T1、T2低信号。结论:霉菌性鼻窦炎有较特征性的CT、MRI表现,CT对病灶内钙化显示较MRI更明确,而且经济,是首选的影像检查方法,MRI在评估病变窦腔外受累及与肿瘤鉴别方面优于CT。
Objective: To investigate the value of CT and MRI in the diagnosis and differential diagnosis of fungal sinusitis. Methods: The CT and MRI findings of 32 patients with fungal sinusitis were analyzed retrospectively. Results: The CT manifestations of fungal sinusitis were mainly as follows: ①90.6% of the lesions had high density calcification. Mostly spotted, located in the central sinus, and the sinus wall has nothing to do. ② 50.0% of the sinus wall there is bone destruction, common in the maxillary sinus medial wall, which is characterized by sinus wall hyperosteogeny. Mycotic sinusitis MRI showed maxillary sinus lesions showed most of the T1, T2 low signal. Conclusion: Mycotic sinusitis has more characteristic CT and MRI manifestations. Computed tomography (CT) is more accurate and economical than intracranial calcification in MRI. It is the first choice of imaging examination. MRI is an effective imaging method for evaluating extracavitary involvement and tumor identification Better than CT.
