Neurolymphomatosis (NL) is a rare condition caused by non‐Hodgkin's lymphoma or leukemia. We present a case of NL and describe ultrasound features, including the “fried egg sign” in which there is a clear demarcation between an avascular echogenic core and a hypoechoic vascularized peripheral zone that may help to distinguish NL from primary nerve sheath tumors.
