  • Title: Sonographic characteristics of peripheral nerve sheath tumors.
    Author: Reynolds DL, Jacobson JA, Inampudi P, Jamadar DA, Ebrahim FS, Hayes CW.
    Journal: AJR Am J Roentgenol; 2004 Mar; 182(3):741-4. PubMed ID: 14975979.
    Abstract:
    OBJECTIVE: We have found variability in the sonographic appearance of peripheral nerve sheath tumors. The purpose of this study was to characterize the sonographic appearances of pathologically proven peripheral nerve sheath tumors. CONCLUSION: Peripheral nerve sheath tumors are often hypoechoic with posterior acoustic enhancement and so may simulate a ganglion cyst. The presence of intrinsic blood flow on color Doppler sonography and peripheral nerve continuity suggests the diagnosis of peripheral nerve sheath tumor. Sonography cannot reliably distinguish neurofibromas from schwannomas.
