摘要
目的：分析颈部少见肿瘤的影像表现。材料与方法：回顾分析颈部少见肿瘤３３例的影像表现与病理基础。本组良性３０例，恶性３例。临床主要以颈部肿块就诊。血管性、神经性和淋巴性肿瘤占本组７８７％。结果：Ｘ线平片表现为颈部肿块密度增高、气管受压、移位、狭窄。血管造影表现为颈动脉受压、移位，肿瘤供血血管显示。Ｂ超示肿块为不均匀的低回声区。ＣＴ表现为肿块边缘光滑，密度均匀或不均匀。大多数肿块发生在颈动脉间。结论：影像诊断与肿块穿刺相结合，诊断准确率高。ＣＴ对颈部解剖较清楚。
PURPOSE:To analyse imaging features of rare neoplasms of the neck. MATERIALS and METHODS:Retrospective analysis of the imaging manifestations and its pathologic basis was done in 33 cases of rare neoplasms of the neck,of them there were benign in thirty and malignant in three.Clinically the chief complains in most patients was presence of a mass in the neck.The vascular leurogenic and lymphatic neoplasms account for 78 7% in our group.RESULTS:X-ray plain film showed high density mass in the neck and compression,shifting and stenosis of the trachea.Angiography demonstrated displacement of the carotid artery and supplying vessels of the tumours.On B- mode ultrasound,and inhomogeneous hypo-echoic mass was seen.A homogeneous or inhomogeneous mass with smooth margin can be found by CT scan.Most tumour occured in the carotid artery space.CONCLUSION: High diagnostic accuracy can be reached by imaging investigation combined with needle biopsy of the mass.The advantage of CT is good demonstrating of the anatomic details of the neck,which may be helpful to operation planning.
