The most important question would be what is the cause of the enlargement of the lymph node?
What are the various possibilites?
Is it cancerous or non cancerous?
What are the investigations need to be done?
The size of the lymph node is quite significant and this warrants a CT guided aspiration biopsy cytology (ABC). This will give the diagnosis. It can be;
1) Benign; reactive lymphadenitis.
2) Non specific lymphadenitis.
4) Secondary enlargement due to some visceral cancer.
With no symptoms and no abnormality found in CT scan and MRI, there is an high chance of this being an incidental non cancerous finding which does not have clinical significance. Thus would not warrant treatment.
Please feel free for your follow up questions.
I would be happy to assist you further, if you need any more information.
With a laparoscopic approach, this will be completely removed. Usually the biopsy report takes around 5 days to come which only determines about the cancerous or non cancerous lymph nodes. But since it is removed completely, a residual lymph node is not left.
