The CT is useful to detect the number and site of nodules in the lungs, invasion of the mediastinum and pleura, hilar lymph nodes as well as spread to any abdominal organ or metastasis to pelvis. It can confirm the location of the sarcoma and show the organs nearby. These are helpful for determining the stage of cancer and in determining whether surgery is a good treatment option. CT scans can also be used to guide biopsy and a biopsy sample is usually removed and looked at under a microscope.

• The CT scan can be used to assess the metastasis to the lungs and mediastinum and also follow up after surgical removal or recurrence evaluation.^[1][2]
• Tumors on CT imagings can be seen as hetergenous mass demonstrating low attenuation representing necrosis.
• Other features include invasion of the mediastinum and pleura and hilar lymphadenopathy.
• CT of pelvic and abdomen is follow up modality of choice after therapy with surgery and/or chemoradiaton.
