真菌性鼻窦炎的CT影像分析

目的：探讨真菌性鼻窦炎的CT影像学特点.方法：回顾性分析经手术和鼻腔内窥镜取材病理证实的48例真菌性鼻窦炎的CT表现.结果：所有受累鼻窦均显示窦腔密度增高,全组病例均累及上颌窦,其中病变累及一侧上颌窦40例,两侧上颌窦8例,一侧上颌窦及筛窦24例,上颌窦内可见点状、斑块状、条线状钙化影44例,窦腔高密度影内可见气泡影16例,病变呈肿块状突入鼻腔10例,窦壁骨质硬化25例,窦壁骨质吸收破坏10例,骨质吸收残骨端均伴有骨质硬化,上颌窦内侧壁破坏8例.病变延伸到邻近结构3例.结论：根据真菌性鼻窦炎的CT表现,可归纳出如下特点：①病变均累及上颌窦,且大部分为单侧性;②病变可表现为软组织肿块突入鼻腔;③窦腔密度增高,其内可见多种形态钙化影,且钙化与窦壁无关系;④局限性骨质增生与破坏,破坏残端常伴有骨质硬化.其中以鼻窦病变内钙化影最具特异性.

Tomogtraphy Diagnosis Of Mycotic Nasosinusitis

Objective：To study the tomographie characteristic of mycotic nasosinusitis. Methods：48 case of mycotic nasosinusitis, which were confirmed by pathology of surgery and endoscope, were retrospectively analyzed. Results： The density of all affected raised,40 cases of them were affected by unilateral sinuses maxillaris, 8 cases of them were affected by hibateral sinuses maxillaris, 24 cases of them were affected by unilateral sinuses maxillaris and ethmoidal anfractuosity, punctate, plaquelike and linear calcified image were found in 44 cases, bubble image in high density were found in 16 cases, tumid focal tissue protrude into nasal cavity were found in 10cases,osteosclerosis of nasal sinuses were found in 25 cases,sclerotin were absorbed and broken were found in 10cases, remanent sclerotin sclerosis was found most in medial nasal cavity, vicinal affection was found in 8case. Conclusion.. （1）Focus of infection is most unilateral, All tumors involved the maxillary sinus. （2）Tumid focal tissue protrude into nasal cavity. （3）The density of na- sal cavity raised, Many forms calcified images were found in it. （4）Circumscribed hyperosteogeny and destruction of bone,osteosclerosis in remanent sclerotin were found, calcified image in nasal cavity is distinctive
