摘要

摘要: 目的：探讨上颌窦出血性息肉的CT、MRI表现，总结影像学特点，为临床诊断提供帮助。方法：回顾性分析27例经手术病理证实的上颌窦出血性息肉CT、MRI影像学资料。针对病变部位、形状、范围，窦壁骨质改变，病变边缘及周围结构情况，病变密度或信号，各期增强扫描的强化方式、幅度及范围进行统计分析。结果：27例患者均为单侧发病。均行CT平扫，其中9例行双期动态增强CT检查，11例行MRI检查，其中6例行MRI增强检查。CT平扫见单侧上颌窦充满等低混杂密度影并累及鼻腔，上颌窦不均匀膨大变形，伴局部骨质吸收破坏27例，但未侵犯邻近结构，CT增强扫描病变内见点片状血管样显著强化及进行性强化。MRI能清楚区分病变及阻塞性鼻窦炎，病变均形态不规则，呈混杂信号，T1WI主要为中等信号8例、稍低信号3例，混杂少量高信号；T2WI呈高低混杂信号，边缘见不规则低信号环。增强呈多发结节状、斑片状不均匀明显强化。结论：上颌窦出血性息肉CT显示实变上颌窦不规则膨大变形伴骨质压迫吸收对本病有一定提示作用，血管样显著强化及进行性强化是本病的特征性增强CT表现，MRI具有非常典型的影像学表现，T2WI呈高低混杂信号和低信号环，增强呈多发结节状、斑片状不均匀明显强化，能清楚地显示病变与周围软组织无侵犯征象。具有较好的诊断价值。术前CT和MRI检查对该病的术前诊断有重要意义。

Abstract: Objective: To explore the CT, MRI manifestations of the polyp of maxillary sinus cavernous hemangioma. To summarize the imaging characteristics and it may assist doctors to diagnose infarcted angiomatous polyps in maxillary sinus with further developing.Method: A retrospective analysis of the CT, MRI manifestations and clinical analysis about 27 casesconfirmed by surgery pathologywho are maxillary sinus cavernous hemangioma.Result: Twenty-seven cases were unilateral diseases, and clinical manifestations were nasal congestion. Twenty-seven cases were proceeded CT scan, of which 9 cases of double-phase dynamic enhanced CT examination, 11 cases with MRI examination, of which 6 cases with MRI enhanced examination.CT scan showed unilateral maxillary sinus full of mixed density and involving the nasal cavity, maxillary sinus abnormal expansion of deformation, with local bone resorption damage in 27 cases, but without violation the adjacent tissue. CT enhanced scan of lesions shows that the spotted blood vessels were significantly enhanced and progressive enhancement. MRI can clearly identifylesions and obstructive sinusitis and morbid shape was irregular with mixed signal;T2WI showed high and low mixed ring signals, and the edge of the irregular low signal ring, with enhanced nodules and patchy unevenly enhanced.Conclusion: Most polypof maxillary sinus cavernous hemangioma clinical manifestations are unilateral nasal obstruction. CT shows the maxillary sinus irregular expands and compression bone absorption with a prompt action to this disease.Vascular-like enhancement and progressive enhancement are characteristic enhanced CT manifestations of this disease. MRI can better show the lesion range. T2WI with high and low ring mixed signals, low ring signals, and mostly enhanced nodules, uneven enhancement of plaqueare characteristic imagingmanifestations.
