ct scan showed mult irr non calcified lung nodules

Had ct scan after an irr chest x-ray.  Ct scan showed : multiple irr.non calcified nodules ranging from 10mm. - 212mm.in size.  Mostly in the right lung, with a few in left lung. Most of the nodules in the right lung reside in the upper lobe.  I am a 50 year old non smoker which has been exp.night sweats, elevating b/p, low blood sugar, right sided back pain.  Should I be concerned?  I was refered to a pulmonologist today.
Also, I have edema in my extremities which is unusual for me.  Any help would be appreciated. Thank you for your time.

212 mm? or did you mean 10 mm - 12 mm?  Let us know how your visit with the pulmonologist goes!

I also have multiple nodules on my lungs. I was diagnosed with Sarcoidosis. If you didn't see your Pulmonolgist yet, maybe you can ask about it.

Hi there.  Multiple pulmonary nodules are commonly encountered in metastatic disease of the lungs. Other less common causes are infections, arteriovenous malformations, wegener’s granulomatosis and lymphoma. Secondary lung tumors manifest as discrete nodules, usually multiple, interstitial infiltrate or endobronchial lesions with or without distal atelectiasis and charcterisitc round appearance on x-ray chest. Any cancer has the ability to spread to lungs most common being bladder, colon, breast and prostate cancer. You will need a PET scan to confirm and differentiate from pneumoconiosis since malignant cells have higher rate of glucose metabolism.  Thus, the principle of PET scan is intracellular accumulation of FDG and preferential accumulation of glucose in malignant cells, leads to visualization of malignancy on PET scan. It is the diagnostic and staging tool in cancer, assesses malignant potential in a pulmonary nodule if it is solid and more than 1 cm in dia. management would depend on the diagnosis. Primaries would need to be searched if these are secondaries.You have non-specific symptoms like significant weight loss too.  You can discuss with the pathologist the feasibility of transthoracic needle biopsy of the nodule. Consult a pulmonologist soon and peripheral edema also needs ruling out of congestive heart failure or venous obstruction due to cancer. Hope this helps. Take care.
