Soft Sarcoma Appear X Ray
Rarely.: If you are talking about a plain, standard, old-fashioned x-ray, soft tissue sarcoma rarely appears because these types of x-rays are really designed to evaluate bones. Soft tissue sarcomas are usually fleshy and better evaluated with ct scans (a different kind of x-ray), or mri. Sarcoma that has spread to the lungs can be see on a plain chest x-ray thought. ...Read moreSee 2 more doctor answers
By definition, it is malignant (i.e., being locally invasive and at least theoreticlally capable of metastasizing), and arises from / mimics muscle or connective tissue elements that are not marrow or immune / white cells. The sarcomas are a tremendously varied and troublesome family of tumors, though thankfully less common than carcinomas and the leukemia / ...Read more
Usually misses it: You asked about this before. A chest xray almost always will miss Kaposi sarcoma, which doesn't usually cause lung or chest problems. If someone doesn't have KS skin lesions, they have little chance of having it anywhere else in the body. If you remain concerned, discuss with your personal physician. ...Read more
Yes: Why do you ask? If you are HIV positive, there are many other possibilities to explain pulmonary symptoms. Kaposi's spreads along the fibrous septa of the lungs and will be visible to the radiologist as increased interstitial markings if it is symptomatic. I am glad you are health conscious. Best wishes. ...Read more
Not always.: Kaposi Sarcoma in the lung may not be visible on a simple chest x-ray. It may require a more advanced study called a Chest CT which allows doctors to look inside the lung on a more high resolution level. There are many cases when someone with KS in the lung had a normal chest xray. Hopefully this answers your question. ...Read moreSee 1 more doctor answer
As a hiv positive can I believe that a chest x-Ray is enough to eliminate possible Kaposi sarcoma of the lungs?
Probably yes, but...: When Kaposi sarcoma develops in advanced HIV infection, the first evidence almost always is on the skin. If you have normal skin, you can safely assume you don't have it in your lungs. KS develops only in advanced immune deficiency due to HIV. If you have a high CD4 count and low viral load, and especially if on proper treatment with ARV drugs, KS is low risk. Discuss with your HIV doctor/clinic. ...Read more
Can MRI & X-ray miss sarcoma(both say normal)? 1-2cm bump near subcutaneous vessels in arm, they're normal on MRI. Can it still be cancer? next step?
Scanner and techniqu: Cancer is a microscopic diagnosis. BUMP is a clinical observation. MRI should characterize the size, shape, margin, blood flow and invasion of the surroundings to help the Radiologists to suspect benign versus aggressive BUMP. The aggressive can mean cancer or acute infection. Good luck on your biopsy if it looked aggressive. Depending on the MRI scanner and tetechniques you can identify 3mm. ...Read more
Is a chest x-Ray enough to eliminate the possibility of Kaposi sarcoma in the lungs? Addressed for hiv positive individuals. No skin lesions
Suggest CT: Three reasons CT is better than chest x ray for this situation: 1) Kaposi sarcoma can be subtle on CXR, esp if early. 2) CT is by far better at showing otherwise occult disease in the chest. 3) The chances of an HIV pt. having other problems that only CT might see is not insignificant. ...Read more
vessel feel hard w/tiny lump, bigger when arm bent above pronator teres muscle. MRI/X-RAY clear. Dr not worried, is MRI wrong? What is it, Sarcoma?
Bumped tibia mid-July. Have hard lump on same area. GP took x-rays and said it's subcutaneous scar. This possible? Afraid of soft tissue sarcoma.
Depends: If you had a pretty severe blunt injury to the tibia, a bone contusion can occur which can be associated with a "lump" in that area that should gradually resolve. If it was a minor injury and you have a pretty large growth in that area, you may want to have it looked into further. An MRI would be the test of choice to do so. ...Read more
Fell down stairs, banged shin last July. Recently found hard lump in same area. GP took x-rays, says it's subcutaneous scar. Chances of ST Sarcoma?
Sensitive area: This is a sensitive area and the bone is very close to the surface. If the original injury went completely away this is probably unrelated. Xrays are helpful and sarcoma should be distinctive on plain films. Why do you think it is sarcoma? It is an improbable diagnosis but if there is any question further evaluation is absolutely necessary. ...Read moreSee 1 more doctor answer
