【摘要】：正患兒男,1歲,因"右眼疑似不轉(zhuǎn)動1年"入院�；純撼錾蟛痪眉幢话l(fā)現(xiàn)右眼球不能轉(zhuǎn)動、右上眼瞼下垂。眼底檢查未見明顯異常。影像學(xué)檢查:副鼻竇CT平掃示雙側(cè)上頜竇黏膜增厚,右側(cè)鼻腔內(nèi)見軟組織密度影填充,并突入右側(cè)篩竇及上頜竇,使竇腔擴大,竇壁骨質(zhì)變薄,鼻中隔向左偏曲(圖1)。頭顱MR平掃示右側(cè)鼻腔內(nèi)較均勻等T1等T2異常信號(圖2),FLAIR呈等信號,DWI呈略低信號,增強后明顯均勻強化;病灶形態(tài)規(guī)則,邊界清楚,呈膨脹性生長,壓迫鄰近篩竇及上頜竇,向后壓迫右側(cè)眼眶后方致視神經(jīng)管狹窄,視神經(jīng)受壓移位。
[Abstract]:A 1-year-old male patient was admitted to hospital because his right eye was suspected not to rotate for 1 year. Soon after birth, the child was found to be unable to turn the right eye ball and droop the right upper eyelid. Fundus examination showed no obvious abnormality. Imaging examination: paranasal sinus CT showed bilateral maxillary sinus mucosa thickening, soft tissue density filling in the right nasal cavity, and projecting into the right ethmoid sinus and maxillary sinus. The sinus cavity was enlarged, the sinus wall was thinned, and the nasal septum was deviated to the left (Fig. 1). Cranial Mr plain scan showed that the right nasal cavity had a more homogeneous iso-T _ 1 and T _ 2 abnormal signal (Fig. 2) flair showed a slight low signal intensity on the same signal intensity and obvious homogeneous enhancement after enhancement, the lesion had regular shape, clear boundary and expansive growth, and compressed the adjacent ethmoid sinus and maxillary sinus. Posterior compression of the right orbital resulted in stenosis of the optic canal and compression and transposition of the optic nerve.
