* 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.


Morphological imaging features usually depends upon the site of the Leiomyosarcoma but generally it is suggestive of heterogeneous mass,demonstrating central low attenuation representing the necrosis and rarely with calcification.

Overview

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.
