Schwannomas and paragangliomas, when localized superficially, are examples of tumors that are well accessible with sonography. Their appearance on ultrasound can be diverse due to variable echogenicity and vascularization. In some cases, especially in the event of multicentricity or an inability to demostrate contiguity with a nerve of origin, they can be mistaken for pathologic lymph nodes. The appearance of these tumors on conventional ultrasound and on contrast-enhanced ultrasound using the microbubble contrast agent SonoVue (Bracco Imaging, Italy) is presented in case reports of three patients undergoing investigation of palpable masses in the neck or axillary region. All patient underwent excisional biopsy of the lesions, which were histologically determined to be schwannoma of the neck and axila, and paraganglioma of the neck.
