摘要
目的探讨高频超声诊断表皮样囊肿的价值。方法回顾性分析63例经手术和病理证实的表皮样囊肿患者的超声表现。结果本组63例患者共计66个病灶,其超声表现可分为3型,分别为均质回声型18个、不均质回声型40个、混合回声型8个。彩色多普勒显示所有病灶内均未见血流信号,4个混合回声型病灶在囊周可见较丰富点、条状血流信号。结论高频超声对诊断表皮样囊肿具有重要价值。
Objective To investigate the value of high frequency ultrasound in the diagnosis of epidermoid cyst. Methods The ultrasound images were retrospectively analyzed in the 63 patients with epidermoid cyst confirmed by surgery and pathological test. Results A total of 66 lesions were detected in 63 patients and the features of images could be classified into 3 types including 18 cases of homogeneous echo pattern, 40 cases of inhomogeneous echo pattern, 8 cases of mixed echo pattern, respectively. Blood flow signal could not be detected within all types of lesions, but markedly increased punctiform and strip blood flow signals could be detected around the lesions in 4 cases of mixed echo pattern. Conclusion High frequency ultrasound is of important value in the diagnosis of epidermoid cyst.
