[[Computed tomography]] (CT) scan and [[biopsy]]: CT scans are often used to diagnose [[mesothelioma]]. It can confirm the location of the cancer and show the organs nearby, as well as lymph nodes and distant organs where the cancer might have spread. These are helpful in staging the cancer and in determining whether surgery is a good treatment option. And CT scans can also be used to guide biopsy and a biopsy sample is then removed and looked at under a microscope.

*The appearance is that of a [[soft tissue]] attenuation nodular [[mass]] which spreads along [[Pleural|pleural surfaces]] including into [[pleural]] [[fissures]] and often creating a [[pleural]] rind.
*[[Calcification]] is seen in 20% of cases which usually represents engulfed calcified [[pleural]] [[plaques]] rather than true [[tumor]] [[calcification]].
*Sarcomatoid variants may demonstrate [[osteosarcoma]] or [[chondrosarcoma|chondrosarcomatous components]] which may also be [[Calcified lesion|calcified]].
*An rare variant is the [[solitary]] [[mediastinal]] [[malignant]] [[mesothelioma]] which has appearance of a [[solitary fibrous tumor of the pleura]].<ref name="MRimesothelioma1">Radiographic findings of mesothelioma. Dr Bruno Di Muzio and A.Prof Frank Gaillard et al. Radiopaedia 2016. http://radiopaedia.org/articles/mesothelioma. Accessed on February 8, 2015</ref>
*[[Mesothelioma]] may be associated with direct [[invasion]] of adjacent structures ([[chest wall]], [[diaphragm]], and [[mediastinal]] content) but also frequently [[metastasis]] to the [[contralateral]] [[lung]] and [[Lymph nodes|local nodes]].
*[[Chest wall]] [[invasion]] is suggested by direct [[extension]] in [[bone]] or [[muscle]] identified on CT scan.
*Presence of a [[pericardial effusion]] suggests transpericardial [[extension]].<ref name="MRimesothelioma1">Radiographic findings of mesothelioma. Dr Bruno Di Muzio and A.Prof Frank Gaillard et al. Radiopaedia 2016. http://radiopaedia.org/articles/mesothelioma. Accessed on February 8, 2015</ref>
