This is what my report says for usg scan of the neck " a large left upper deep cervical solid cystic well circumscribed nodule of 5.5 into 3 into 4.5 CM is noted, along the posterior aspect of left carotid sheat, splaying the left carotid artery and internal jugular vein. It is mildly on Doppler interrogation. The neck vessels otherwise appear normal. No focal solid cystic lesson no significant cervical lymphadenopathy. Impression large left neck mass as described-s/o vagus nerve schwannoma" please suggest and this swelling near my neck is not painful. thanks
