What Causes Enlarged Lymph Node And High WBC Count?

Hi.. my 2-month old son has a WBC count of 27,000. X ray shows he has pneumonia. He was given antibiotics tru IV fluids, then it went down to 22,000, but after 3 days of oral antibiotics, the wbc went up to 25,000. He also has his lymph node enlarged (below the left ear). Is it because of pneumonia? thanks

Pediatrician,  's  Response
Hi, I'am Dr Suresh K Yadav MD (paediatrics), I had gone through your question and understand your concerns,

X ray showing pneumonia , high WBC counts can be explained by pneumonia . You have not mentioned size of lymph node, it it tender , is single node enlarged or others are also enlarged . Lymph node enlargement is not due to pneumonia , it may be related to factors responsible for pneumonia . If there are significant lymph node enlargement, especially if persists after antibiotics treatment one need to rule out other causes by detailed peripheral blood film examination for any abnormal cells, Mantoux test, ESR and if required biopsy of lymph node .

Hope this answers your question. If you have additional questions or follow up questions then please do not hesitate in writing to us. I will be happy to answer your questions.

Take care
