Abstract
Objective To evaluate the value of ultrasonography in diagnosing intraneural ganglion cysts. Methods The ultrasonographic images of 12 patients with intraneural ganglion cysts confirmed by surgery and pathology were retrospectively analyzed. The ultrasonographic features were summarized. Results The ultrasonographic images showed the location, number, size, shape, boundary, internal echo, involvement extent and blood supply in intraneural ganglion cysts clearly. Intraneural ganglion cysts showed cystic masses within peripheral nerve, boundary clear, irregular-shaped, ill-acoustic transmissibility, and separations are common, color Doppler examination showed no blood flow inside the cysts. Conclusions High frequency sonography is the preferred imaging method for diagnosis of intraneural ganglion cysts. Key words: Ultrasonography, Doppler, color; Intraneural ganglion; Cysts
