Infection or Cancer? CT neck with IV contrast results are scaring me; I discovered a lump on the right side of my neck about 2 years ago. My primary care sent me for a thyroid ultrasound in November of 2013 which was negative for any nodules. I went for another physical in February of 2015 and she sent me for a CT scan to get a closer look because she suspected cancer. My results showed (1) mildly enlarged bilateral upper cervical lymph nodes, nonspecific. There is a cluster of 3 lymph nodes in the region of palpable concern. (2) Mild enlarged bilateral tonsils. No peritonsillar inflammation. (3) Bilateral cervical ribs at C7. She is suspecting it is an inflammatory or infectious process and has prescribed me two weeks of Amoxicillin and a follow-up appointment. If the nodes haven t gone down she wants to biopsy it. My question is can this be a long-lasting result of an infection with mononucleosis? Or can I have some issue going on with my tonsils? Does this sound like cancer such as Hodgkin s or Non-Hodgkin s? Any advice would be great thanks! I will list the measurements below: Cluster of 3 lymph nodes in this region (level II) are mildy enlarged measuring 1.7cm, 3 cm, and 1.6cm in long axis. Enlarged left level II lymph node is also seen measuring 2.3cm. There are additional left level II lymph nodes which are not enlarged by size criteria. There is enlarged left level III lymph node posterior to the internal jugular vein measuring 2cm in long axis. There are additional bilateral level IV lymph nodes which are not enlarged by size criteria. These are nonspecific. These may be infectious or inflammatory. There is no submental or submandibular lymphadenopathy.
