Ultrasound says hypoechoic mass with essentric fatty hilum favoring an enlarged lymph node on left side of neck. what does that mean ?

Probably benign node: When a mass is palpated in the neck it is usually abnormal and suggests a new, possibly metastatic lesion requiring bx and then therapy. If a hypoechoic mass is noted this is a solid lesion and with above description is a lymph node that is characterized by the fatty hilum. If lesion enlarges bx needed unless a primary lesion defined that may be causing nodal enlargement. Therapy then needed
