[|Human|] Good evening, In September 2011 I had a CT scan for an unrelated chest pain which turned out to be pericarditis but incidentally found out that I had 2 4mm ground glass nodule at the base of my left lung . As well they also found a unidentified nodule on my liver which they recommend a ultrasound for. I did go for the ultrasound and they told me it was a hemangioma . I did a follow up CT scan 4 months later where they found the same 2 4mm nodules but also they found 2 more nodules less than 4 mm..They also found another nodule on the top of my liver which is unidentified and another ultrasound was recommended. i would like a little feedback on this if its anything to be concerned about since I am thyroid cancer survivor for the past 5 years. I was concerned that they found two more nodules and my family doc seems concerned as well...looking for some advice
[|AI|]  Hi, Thanks for writing in. I would be in a better position to help you if you could tell me the type of thyroid cancer you were diagnosed with. Papillary and Follicular cell cancer remain the most common types of thyroid cancers which are diagnosed. These rarely, if at all spread to the liver. Papillary cancers spread to the lymph nodes and follicular cancers spread to the local tissues and to the bone and lung. Haemangiomas are some of the most common masses seen in liver, and they do not cause cancers. They can also be multiple Having said that, the only way of definitely knowing whether this is cancer is by doing a Fine needle aspiration cytology. This could lead to bleeding if the tissue is haemangioma. Another way of differentiating would be the PET scan or an enhanced MRI but the availability, cost and insurance coverage could be issues. Hope this helpsRegards
