Value of high frequency sonography in diagnosis of peripheral nerve lipofibroma hamartoma / 中华超声影像学杂志

ABSTRACT

Objective To study the value of high frequency sonography in diagnosis of peripheral nerve lipofibroma hamartoma.Methods The high frequency sonography images of seventeen patients with diagnosed peripheral nerve lipofibroma hamartoma were retrospective analyzed.The sonography features were compared with clinical surgery.Results The position and internal structure of nerve can be found by high frequency ultrasound,and which nerve fascicle,location and scope of lipofibroma hamartoma can be displayed clearly.The involved peripheral nerve was showed expansive growth.Because the hyperechoic fat tissue and hypoechoic nerve fibers alternated with one and another,the feature of high frequency sonography was lotus-like,there was no blood flow signal in nerve.Conclusions High frequency sonography is the preferred imaging method for diagnosis of lipofibroma hamartoma.
