目的 :探讨鼻窦真菌病的CT表现特征。材料和方法 :回顾分析103例手术和病理证实的鼻窦真菌病的CT表现 ,其中累及上颌窦及蝶窦分别为93和10例。结果 :病变未充满窦腔56例(54.4 %) ,充满窦腔47例(45.6 %)。密度不均匀87例(84.4) ,均匀16例(15.6 %)。全窦腔受累者 ,其病变中心密度高于外周密度 ;病变涉及部分窦腔者显示为中央不规则的高密度软组织团块影伴窦壁黏膜增厚。93例上颌窦真菌中 ,41例有高密度软组织团块突向中鼻道伴骨性窦口扩大和骨质侵蚀。所有受犯鼻窦均伴有窦壁骨质增厚和硬化。91.3 %的病例在高密度软组织病变内还可见钙化。所有行增强后扫描者均未见强化表现。结论 :鼻窦真菌病具有特征性的CT表现 ,CT平扫应作为本病首选检查方法。
Objective: To investigate the CT features of sinusitis. Materials and Methods: A retrospective analysis of 103 cases of pathologically confirmed sinusitis fungal CT findings, which involved the maxillary sinus and sphenoid sinus were 93 and 10 cases. Results: 56 cases (54.4%) were filled with sinuses and 47 cases (45.6%) filled sinus. There were 87 cases (84.4%) with uneven density and 16 cases (15.6%) uniformly. The total sinus involvement, the lesion center density higher than the peripheral density; lesion involving part of the sinus cavity were shown as irregular central high-density soft tissue mass with sinus wall mucosal thickening. In 93 cases of maxillary sinus fungus, 41 cases had high-density soft tissue mass protruding toward the middle part of the nasal cavity with osseous ostia and bone erosion. All offenders were accompanied by sinuses sinus sinus thickening and hardening of the bone. 91.3% of cases also showed calcification in high-density soft tissue lesions. None of the scanners enhanced after all rows were enhanced. Conclusion: Sinus mycosis has characteristic CT manifestations, CT scan should be the preferred method of detection of this disease.
