Neurolymphomatosis or paraneoplastic syndrome? - #15982
Good morning, I will try to summarize my history for an opinion, even though I am aware of the limitations of distance. In the first week of August, I noticed a swollen, non-tender retroauricular lymph node (right ear). In September, I had an ultrasound which showed no suspicious features, and I was only told to repeat it if I noticed an increase in size. One night in mid-October, I woke up completely sweaty and shivering, and I realized I had a low-grade fever. This low-grade fever (max 37.7°C) lasted 2 days, but at night I started having strange tingling sensations in my legs that kept me from sleeping, and on the fourth day from the onset of the fever, I felt a searing burn in my right leg for several hours. From that moment until now, over a month later, my right leg is constantly weak, numb, sometimes with burning/pain extending to the sole of the foot, and my left arm is also weak and lacks strength (to a lesser extent than the leg). The night sweats continued intermittently for 2 weeks and have now disappeared. Over the course of this month, I underwent: 2 further ultrasounds of the lymph node stations which showed reactive lymph nodes with no suspicious characteristics. CT scan of the neck, chest, and abdomen without contrast: Reported small reactive lymph node nodules. The mediastinum showed some subcentimetric, reactive-looking lymph node nodules. Some reactive lymph node nodules in the lomboaortic area and a greater number in the inguinal area, non-liquefied and non-confluent. Blood tests (all normal): Complete blood count with smear, LDH, Beta-2 microglobulin, iron and ferritin levels, ESR, CRP, protein electrophoresis, Bence Jones protein in the serum, complete urine test, ANA, and rheumatoid factor. Serology: Positive EBV IgG, negative EBV IgM; Anti-Herpes positive IgG only; Cytomegalovirus and Toxoplasmosis all negative. Electromyography (EMG): Performed 2 weeks after the onset of symptoms, negative. MRI without contrast of the brainstem and spinal cord: All normal except for "Verticalization of the physiological cervical lordosis," "Diffuse protrusion of the posterior disc margin of L4/L5 with impression on the dural sac," and "Slight posterior median and bilateral paramedian protrusion at L5/S1 impressing the dural cul-de-sac." I had two hematological consultations where, in light of the performed tests, I was told there is no trace of lymphoproliferative disease. The neurologist, after prescribing the EMG and MRI without contrast, advised me to see an orthopedist. Unfortunately, however, my arm and leg symptoms have been constant for over a month now. I have read in scientific articles that lymphoma can, in rare cases, present with symptoms very compatible with mine, by infiltrating the nerves or due to a paraneoplastic syndrome. I am very worried and hope for your kind feedback. Thank you in advance.

Doctors’ responses
Hello,
🛑Your findings do not fit lymphoma or paraneoplastic disease. A post-viral neuropathy or disc-related radiculopathy is far more likely. Your tests (blood work, ultrasounds, CT, MRI, EMG) all show reactive lymph nodes only and no signs of lymphoma.
Normal LDH, β2-microglobulin, CBC, and imaging make lymphoma, neurolymphomatosis, and paraneoplastic syndromes extremely unlikely.
Your symptoms began right after a brief fever, which strongly suggests a post-viral neuropathy or nerve root inflammation.
The L4/L5 and L5/S1 disc protrusions can explain the persistent symptoms in your right leg.
Arm symptoms may come from cervical muscle tension or radiculopathy.
🛑Recommended next steps: spine MRI with contrast, repeat EMG, and evaluation by a neurologist or spine specialist.
I trust this helps Feel free to talk Thank you
Hi Doctor, thanks for your reply. Other symptoms have appeared over the last week (every day): loss of appetite, nausea, abdominal pain and slower digestion. Is this related to neuropathy? Thanks again.
Hello,
Your new symptoms are compatible with: Post-viral autonomic nerve irritation Small-fiber/autonomic neuropathy
They do not suggest a malignant cause and they commonly occur together with the neurological issues you’ve already described.
Thank you
In situations like yours, where the combination of symptoms such as persistent lymph node swelling, night sweats, neurological symptoms, and lingering concerns about lymphoma or paraneoplastic syndromes arises, thorough evaluation can indeed be essential. It’s understandable to have concerns about conditions such as neurolymphomatosis or paraneoplastic syndromes given the tests you’ve undergone. Although both are rare, lymphoma can occasionally present with neurological symptoms if it affects the nervous system directly (neurolymphomatosis) or through paraneoplastic processes. However, the normal hematological evaluations, imaging, and absence of overt signs of malignancy in your lymph nodes and other tests points against lymphoma at present. The negative neurological work-up, including the EMG and MRI, helps exclude significant nervous system structural pathology, though it doesn’t necessarily rule out all potential neurological origins.
Given the complex symptomatology, it may be valuable to consider further diagnostic avenues or expert consultations, possibly in neurologic or rheumatologic clinics. Regarding the cervical and lumbar MRI findings, while they might contribute to some of your symptoms through nerve impingement, they don’t fully align with the systemic symptoms like night sweats or arm and leg weakness. Your neurologist’s suggestion to consult with an orthopedist could address whether any musculoskeletal or spinal anomalies might explain part of your symptoms, especially concerning the leg and arm.
If possible, seek a comprehensive review from a neurologist specializing in neuroimmunology or neuro-oncology or a rheumatologist to explore the possibility of rare neurological involvement or an autoimmune process contributing to your symptoms. It’s encouraging that your main investigations have ruled out immediate red flags, but given your ongoing symptoms, continuation of follow-ups and perhaps seeing specialists with expertise in rare syndromes could bring further insight and peace of mind. Keep monitoring your symptoms and any new issues that might arise, and ensure you continue communicating clearly with your healthcare providers about your evolving condition.
Hi Doctor, thanks for your reply. Other symptoms have appeared over the last week (every day): loss of appetite, nausea, abdominal pain and slower digestion. Is this related to neuropathy? Thanks again.
Hi, I understand why you’re worried, but based on all the tests you’ve already done, lymphoma, neurolymphomatosis, or paraneoplastic syndrome are extremely unlikely.
Your ultrasounds, CT scan, CBC, LDH, ESR/CRP, beta-2 microglobulin, and hematology reviews are all normal, these would usually show clear abnormalities if lymphoma were present.
Your symptoms fit much better with: -Post-viral neuropathy / small-fiber neuropathy (common after viral fevers, and EMG can be normal early) -Lumbar disc protrusions (L4–L5 and L5–S1) causing leg weakness, burning, foot symptoms -Possible nerve irritation + anxiety after a prolonged illness
What you should do next:
1. MRI of the spine WITH contrast (this is the right test to fully rule out nerve infiltration).
2. Repeat EMG after 6–8 weeks (early EMG can be normal).
3. Neurology follow-up for post-viral neuropathy or radiculopathy.
4. Blood tests: Vitamin B12, Vitamin D, TSH, HbA1c.
Your symptoms are real, but with all normal cancer-related tests, this is almost certainly a benign nerve issue, not lymphoma.
Feel free to reach out again.

Hello dear See as per clinical history the tests are not in support of either paraneoplastic syndrome or lymphoma or cancer However if you are having doubt get following tests done and share with neurologist/orthopedic surgeon Lems or anti-achr Anti-ma2 Pet scan Gaba-b Mri / ct scan Emg Muscle biopsy Please share the result with orthopedic surgeon or neurologist for better clarity Also, In addition please share clinical pic for confirmation Regards

Hello dear Thanks for the kind response See directly they are not related with the nerve involvement but to see the chances of any advancement, you need to get in person consultation with neurologist. Kindly get complete clarification in person with concerned physician Regards
Hello Massimo By going through your history and evaluation of your health status I must say that nothing to Worry about . It’s not lymphoma nor its paraneoplastic syndrome . Don’t always believe on Google. It’s better to be postive and go for better evaluation. I am suggesting you following treatment as follows- Neurobion forte - once a day after food for 30 days Amoxicillin 625 - once a day after food for 7 days Gabapin nt - once a day after food for 7 days
Nothing to Worry and be positive. You will get fine soon. And consult be further after 7 days
Thank you
Your tests, imaging, clinical course, and physical findings all strongly exclude lymphoma. Your symptoms are far more consistent with a post-viral neuropathy + lumbar disc irritation.
You have been appropriately worked up. Nothing in your history points toward cancer.
You are dealing with a real problem, but not a dangerous one.
