Your report
A diagnosis of idiopathic multicentric Castleman disease (iMCD) requires the presence of multiple swollen or enlarged lymph nodes. In some patients, the swollen lymph nodes may not be visible and may require imaging tests to confirm their presence. These symptoms alone are not enough to diagnose iMCD, as they could be signs of other diseases.
Talk to your doctor if you have any questions about this report.
Additional information about iMCD is available for healthcare professionals at KnowiMCD.com/HCP.

Possible tests
In order to confirm a diagnosis of iMCD, a doctor will need to perform tests to detect the presence of multiple swollen lymph nodes.
- Physical examination
- Lab tests—blood or urine test
- Imaging tests—CT scan, x-ray, MRI, PET scan
- Excisional biopsy
By performing some of the above-mentioned tests, a doctor will be able to eliminate the possibility of autoimmune, cancerous, and infectious diseases. An excisional biopsy of the enlarged lymph node can confirm the diagnosis of iMCD.
The road to diagnosis
iMCD is a rare disease that can be difficult to diagnose because it can mimic so many other diseases. It may take a while to receive an accurate diagnosis because your doctor must rule out several different conditions before suspecting iMCD.
You may start your diagnosis journey at your primary care physician’s office, where you may be referred to a specialist.
Preparing for your appointment
Here are some tips to help you have a conversation with your doctor:
- Write down any symptoms you’ve experienced, even if they may seem unrelated
- Share the results of this Symptom Checker with your doctor
