Pet Ct Head And Neck Cancer Restaging
On chemo for metastic colon cancer . Ct scan coming up - says Neck, thorax , abdomen and pelvis . Is neck usually scanned ?
Yes: There are multiple sites where metastatic colon cancer can appear. While the liver and lung are the most common visceral sites other than lymph nodes in abdomen , spread can occur to the left supraclavicular fossa. Troisier sign is the finding of a hard and enlarged left supraclavicular neck node (Virchow's node). It is a sign of metastatic abdominal malignancy draining the thoracic duct. ...Read moreSee 1 more doctor answer
Cancer is a group of diseases that is characterized by uncontrolled cell growth leading to invasion of surrounding tissues that spread to other parts of the body. Cancer can begin anywhere in the body and is usually related to one or more genetic mutations that allow normal cells to become malignant by interfering with internal cellular control mechanisms, such as programmed cell death or by preventing ...Read more
Thoracic surgeon and radiologist is leaning towards thymoma from pet and CT scans. 2 enlarged nodes near thymus tumor. Can they tell if lymphoma?
Nonspecific pet/ct.: Pet/ct scans are very sensitive for identifying disease, but not as specific as to what type of disease. On some occasions, the appearance and distribution of disease on these scans can specifically identify one disease. More often tissues/nodes would need to be biopsied to be studied under a microscope by a pathologist to specify actual disease type/subtype and can aide in treatment options. ...Read more
Unknown: CT of the brain does deliver radiation but the likelihood of developing malignancy from one or two studies is unknown. One must weigh the benefit to be gained from the study against whatever risk may be present. Careful selection of patients, particularly children is important when considering imaging.

Many kinds could.: The neck is an anatomically complicated region with many internal structures. A ct scan of the neck could show both primary and secondary cancers (tumors that started in the neck and tumors that have spread to the neck from other parts of the body). One primary neck cancer that might be seen on a neck scan is thyroid cancer. Lymphoma is another. Tongue / tonsil / larynx cancers also... ...Read more
Characterize lump: If lump is superficial in location ultrasound is more beneficial in characterizing type of tissue, and may need eventual biopsy. Mr examination for both superficial and deeper soft tissue characterization is usually better than ct examination. Again with all imaging modalities, the final diagnosis depends on biopsy and pathology. ...Read more
How reliable are regular head MRI and chest CT scans to early detect potential recurrence of acinic cell carcinoma of parotid?
Life expectancy for lung cancer gone to brain. Pet scan shows no other cancer now, only 1 tumor on brain. Surgery and whole brsin radiation will be?
"oligometastatic": Patients with a single brain tumor as the only site of metastatic disease are called "oligometastatic." the chance of cure, though small, is real. Every cancer specialist has a few such patients. I would strongly recommend aggressive treatment, including either radiosurgery (cyberknife, gammaknife, etc.) to the brain or surgical resection, and again stereotactic or chemoradiation to the lung. ...Read moreSee 2 more doctor answers

Need biopsy done: A biopsy of one of the axillary lymph nodes may provide some guidance about the primary source of this tumor. It could be breast Cancer which sometimes would not show on a Mammogram(it is called an Occult Primary). Without obtaining tissue for microscopic exam it is difficult to proceed further. Ask his oncologist to provide you some answers and an understanding of this problem. ...Read more
My sister had a uppper rt lung lobectomy last year ...Has non small cell adeonocarcinoma....Ct scans and pet scans every 3 months...Past 2 recent CT scans plus pet scan are showing an increased pleural based nodular density in the rt lower lobe anteriorly
Could be recurrence: This needs to be worked up - it could be recurrent cancer, or possibly reactive, especially if radiation therapy was performed. See the oncologist and ask for specifics about this finding. Was the pet scan positive in the same area? If so, that raises the concern, but it still could be reactive. ...Read moreSee 1 more doctor answer

Imaging/biopsy: The imaging modality of ct scan could show findings that would be concerning for cancer, mass around your colon, enlarged lymph nodes in the same area.

Post neck dissection and head lesion removal. Mets from head to neck. Path results: malignant epithelioid and spindle cell neoplasm-english please. ?
Provisional: This is a preliminary report while the pathologist does more work to get the exact nature of the tumor settled down. I suspect this will turn out to be a carcinosarcoma. This is a difficult case and your physician will probably want several pathologists' signatures on the final report. ...Read more

What are the chances an ultrasound, Mri/mrcp, ercp, and ct scans or imaging miss advanced liver cancer?
If it is tailored: For liver mass, and technically adequate(i.e. no artifacts that might obscure anatomy), it would be nearly impossible to miss a large liver tumor. ...Read more
Both: The actual diagnosis of lymphoma requires tissue, usually excisional biopsy of an entire lymph node. Staging to see where other sites of disease could be is done with a combined PET/CT. The staging used to matter more many years ago when they would often give XRT or do surgery, it doesn't matter as much as it used to because almost everybody gets systemic chemotherapy for both Hodkins and non H ...Read more
Ct uses xrays taken an 360 degrees combined with a computer to see"inside" the body.
