The body is composed of tissue that are classically described as beiing derived from three basic embyonic layers known as the endoderm, mesoderm and ectoderm that then differentiate into the structures that compose the body such as skin, soft tissues, bone, muscle, organs, etc. Stem cells are not differentiated and have the potential to ...Read more
Normal finding: The thymus gland is found in your mediastinum, it is part of your immune system (it helps with the development of your t-cells). It is larger in youth and diminishes in size with age. This is not a finding that suggests a problem. ...Read more
GoBackToThePetBox: At your age the thymus is considered a residual organ, kind of like your appendix.Now,there are some theories as to its function later in life (an immune function or whatever),but overall it just sits there.Of course,it's made of living tissue so there will be some"activity"in it & rarely,can develop a tumor or infection.But in your case who knows?The people who ordered the test in the first place ...Read more
PET scan to investigate a Right Hilar enlarged lymph node1.4cmX.9cm Results: residual thymic tissue mild activity SUV 1.5. This normal? I reCT in 4mo
Possibly: SUV of 1.5 is normal to maybe reactive. This makes it very unlikely to be worrisome. The follow up CT should be improved or no change ...Read more
It is: normal. The thymus normally involutes with age, and it is not uncommon for a young adult to have residual thymic tissue on CT. ...Read more
My CT scan said Mediastinum: residual thymic tissue more then expected for patients age. What does this mean?
Thymus: The thymus is an immune system organ that typically shrinks in size from childhood into adulthood with very little residual tissue left. Unless you are having immune system problems, previous radiation therapy to the chest, or a family/personal history of cancer/growths in the chest cavity, this likely is a benign finding with nothing to worry about. Just ensure follow up with your PCP. ...Read more
My recent CT scan showed residual thymic tissue with no mediastinal adenopathy present. What does this mean and should I be concerned?
CT scan shows "greater prominence of triangular soft tissue in anterior-superior mediastinum suggestive of reactive thymic tissue" Concerned?
Is it normal to have CT scan say stable increased lobulated density in anterior superior mediastinum may represent residual disease vs thymic tissue?
Mediastinum: Of course it depends on many factors. It's normal to see thymic tissue until early 20s is seen in fewer than 50% of people over 40. This density can be possibly be anything including normal, reaction to infection, thymic cysts, or hyperplasia from systemic disease. Fortunately it is stable, but a conversation with your doc and radiologist would be the best thing moving forward. ...Read more
Help with CT chest results.
Residual thymic tissue in the anterior mediastinum. Everything I look up says this is cancer . Is it? Please help
CT scan of chest came back normal but says "Soft tissue in the anterior mediastinum noted,likely residual thymic tissue." thymoma at 21 possible?
My symptom is dyspnea with exertion -5 mos now. All tests say PAVM, but CT scan saw "thymic tissue" in my lungs. What does this mean, should I worry?
At your age,: having some residual thymic tissue in the anterior mediastinum(I assume that's where it is) is normal. ...Read more
Hello, i am 26 years old an recently had a chest ct with dye and it showed thymic tissue, and bibasilar atelectasis... what is this and is it normal?
Not normal: With all these abnormal findings, you need to consult a pulmonologist. The thymic tissue needs further elucidation . What is the reason for the CT chest scan to start with? Do you have myasthenia gravis or some immune defect ? Atelectasis can be explained as airways ending up in a blind alley where there is no longer air sacs to provide air exchange. ...Read more
It may be: just a poorly worded sentence.The thymus gland is not located in the lung, although it is in the thoracic cavity(anterior mediastinum). Residual thymic tissue in the mediastinum is normal at your age. An invasive thymic malignancy could involve the lungs, but otherwise it is impossible to have thymic tissue in the lungs, and even if it was, CT wouldnt be able to tell what it is. ...Read moreSee 1 more doctor answer
I have been told i have resdidue tissue on my thymus gland but not cancerous should i still be concerned?
Need more info: We all have a little bit of residual thymus in adult life. Did you have a thymus tumor that was treated? If you did not have any thymus tumor ever, residual thymus tissue is not a cause for concern, ...Read more
Immune system: Thymus produces white blood cells, called lymphocytes, that travel to lymph nodes throughout the body. There they help the immune system protect the body from infections.Thymus is gland in superior anterior mediastinum helping with immunity in childhood and usually involutes after puberty. ...Read more
3.3cm soft tissue dens ant/sup mediastinum likely residual or reactive thymus tissue? Does ur need biopsy?
Could be either: The thymus tends to involute in adults and often is just a small vestige of an organ. It can however become active under certain circumstances. The most concerning issue would be a thymoma or tumor of the thymus gland. That is often seen in neurological conditions like myasthenia gravis. I would be curious to know how/why this was found. ...Read moreSee 1 more doctor answer
Have chronic cough, small 4mm nodule. 3.3cm soft density tissue in anterior mediastinum. etiologies residual thymus,thymoma,lymphoma. should i worry?
Probably not, but: Chronic cough in a non-smoker is never normal. I doubt that it is connected to the radiological findings. Based on the sizes of the findings I suspect you had a CT scan. See a pulmonary doctor to sort out things, both for the cough and the radiological findings. ...Read moreSee 2 more doctor answers
