目的 分析鼻窦黏液囊肿眼眶侵犯的CT和超声表现,探讨对其诊断和鉴别诊断价值.方法 对2000年5月至2011年12月在天津医科大学第二医院眼科和眼科医院就诊的34例黏液囊肿患者,均经手术治疗和病理证实确诊,结合手术对照分析其黏液囊肿CT和超声表现.结果 34例眼眶黏液囊肿病例中,原发于额窦24例(70.6％,24/34),筛窦9例(26.5％,9/34),上颌窦1例(2.9％,1/34).囊肿范围均超出原发部位,在24例原发于额窦者中,除侵犯眼眶之外,16例蔓延至筛窦,4例侵入前颅窝.9例原发于筛窦者,除侵犯眼眶外,窦内壁向中膈移位,阻塞局部鼻腔.囊肿内密度,23例均匀,11例不均匀.CT值由+19 HU至+88 HU,平均+46.6 HU.9例行强化扫描,均呈环形增强.每例均有窦腔扩大和眶腔间的骨壁吸收,还有4例额窦上壁吸收.囊肿窦内部分的周围骨壁,有不同程度增厚23例.囊肿内侧骨壁向鼻中隔移位或吸收,局部鼻腔闭锁.根据囊肿侵入眼眶的程度,引起内直肌、视神经及眼球向外移位,眼球突出、变形.超声表现:32例黏液囊肿为点状弱内回声,2例缺乏内回声;全部病例显示声衰减不明显.彩色多普勒血流显像检查,34例黏液囊肿内均缺乏血流信号.结论 CT和超声能准确显示病变的位置、形状、大小、边界、内密度或内回声、声衰减程度和继发改变,以及供血状况,对于黏液囊肿的诊断和鉴别诊断有重要意义.
目的 分析鼻竇黏液囊腫眼眶侵犯的CT和超聲錶現,探討對其診斷和鑒彆診斷價值.方法 對2000年5月至2011年12月在天津醫科大學第二醫院眼科和眼科醫院就診的34例黏液囊腫患者,均經手術治療和病理證實確診,結閤手術對照分析其黏液囊腫CT和超聲錶現.結果 34例眼眶黏液囊腫病例中,原髮于額竇24例(70.6％,24/34),篩竇9例(26.5％,9/34),上頜竇1例(2.9％,1/34).囊腫範圍均超齣原髮部位,在24例原髮于額竇者中,除侵犯眼眶之外,16例蔓延至篩竇,4例侵入前顱窩.9例原髮于篩竇者,除侵犯眼眶外,竇內壁嚮中膈移位,阻塞跼部鼻腔.囊腫內密度,23例均勻,11例不均勻.CT值由+19 HU至+88 HU,平均+46.6 HU.9例行彊化掃描,均呈環形增彊.每例均有竇腔擴大和眶腔間的骨壁吸收,還有4例額竇上壁吸收.囊腫竇內部分的週圍骨壁,有不同程度增厚23例.囊腫內側骨壁嚮鼻中隔移位或吸收,跼部鼻腔閉鎖.根據囊腫侵入眼眶的程度,引起內直肌、視神經及眼毬嚮外移位,眼毬突齣、變形.超聲錶現:32例黏液囊腫為點狀弱內迴聲,2例缺乏內迴聲;全部病例顯示聲衰減不明顯.綵色多普勒血流顯像檢查,34例黏液囊腫內均缺乏血流信號.結論 CT和超聲能準確顯示病變的位置、形狀、大小、邊界、內密度或內迴聲、聲衰減程度和繼髮改變,以及供血狀況,對于黏液囊腫的診斷和鑒彆診斷有重要意義.

Objective To study the CT and ultrasound findings of paranasal sinus mucoceles with orbital extension and their value in diagnosis and differential diagnosis.Methods Thirty-four cases were included in this study and all confirmed by operation and pathology.CT and ultrasonography manifestations of these cases were analyzed and compared with the operative findings.Results Among 34 cases with orbital mucoceles,there were 24 cases came from frontal sinuses,9 from ethmoid sinuses and 1 from maxillary sinus.All mucoceles involved periphery sinuses beyond primary location.CT showed the density of 23 mucoceles was homogeneous and 11 heterogeneous.CT value changed from +19HU to 88HU.Mean value was 46.6HU.On contrast-enhanced CT,peripheral sinusmucosa was enhanced in 9 cases.Sinus expansion and bone resorption on sinus walls were found in all 34 cases which resulted in mucoceles protruded into adjacent structures.On B-scan ultrasonograph showed hypoecho in 32 cases mucocele,echoless in 2 cases mucoceles.All cases lacked ultrasound attenuation.All 34 mucoceles absent color flow signal on color Doppler imaging.Conclusions CT and ultrasonography can accurately display the location,shape,boundary and characteristic features of mucoceles and play important roles in diagnosis and differential diagnosis.
