Pattern of spread initially to adjacent pleura. A careful search for malignancy both of the lung lung cancer and pleura mesothelioma should be undertaken especially if nodal enlargement is seen.

Both are deadly forms of cancer that develop in the chest cavity both lead to chest pains and difficulty breathing and both can develop as a result of exposure to asbestos.
Mesothelioma lung ct. However with a history of significant asbestos exposure a diagnosis of mesothelioma can be suggested. Mesothelioma is a rare type of cancer. Ct demonstrates similar nonspecific findings.
Mesothelioma and lung cancer have a lot of similarities. Growth typically leads to tumoral encasement of the lung with a rindlike appearance fig 3. Pleural mass or nodular thickening of soft tissue attenuation.
It typically develops in the thin membrane that separates the lung from the chest wall called the pleura. 1 right lung 2 spine 3 left lung 4 ribs 5 descending part of the aorta 6 spleen 7 left kidney 8. It usually occurs from prior exposure to asbestos a type of mineral fiber used in the insulation industry.
It can also arise less commonly along the abdominal cavity inner or peritoneal lining. The mesothelioma is indicated by yellow arrows the central pleural effusion fluid collection is marked with a yellow star. Ct scan of a patient with mesothelioma coronal section the section follows the plane that divides the body in a front and a back half.
Mesothelioma is a rare type of cancer that that develops in the pleura a thin membrane that separates the lung from the chest wall. 18f fdg petct demonstrates moderate fdg avidity suvmax 78 recurrence of malignant mesothelioma in the left lung red arrow along with scattered bone metastases yellow arrows. Tends to cause inward contraction of the hemithorax eg.
Ct is the primary imaging modality used for the evaluation of mpm. Ct is most commonly used for imaging assessment of mesothelioma and sufficient for accurate staging of disease in most patients. Treatment and prognosis there is unfortunately no proven treatment for asbestosis and although termination of exposure is of course essential it is usually far too late as many years have invariably already elapsed 5 7.
Treatment for mesothelioma lung cancer and other asbestos cancers typically rely on a multimodal approach dependent on the stage of disease. To an expert however mesothelioma and lung cancer are different diseases that require different treatments. Similar to mesothelioma lung cancer is often treated with a combination of conventional treatments like surgery chemotherapy and radiation therapy.
In addition to the previously mentioned findings ct can also be useful in demonstrating invasion of the tumor into the mediastinum chest wall diaphragm and pericardium which aids in disease staging and treatment planning. Mesothelioma can result in breathing difficulties chest pain and fever. Key ct findings that suggest mpm include unilateral pleural effusion fig 1 nodular pleural thickening figs 2 4 and interlobar fissure thickening fig 5.
