How is Mesothelioma Diagnosed?

Story of the Hospital and Mesothelioma Belleties

Mesothelioma is more frequent in patients who have lived in the so-called “white soil” in our country. In addition, cases that occur in the lung membrane in those who have a profession with asbestos exposure suggest mesothelioma.

The most important symptom that emerges in patients is chest pain. This is followed by symptoms such as shortness of breath, fatigue and weakness during effort.


A special examination of the mesothelioma is not available. Findings that are detected in any kind of pulmonary disease are detected: the patient has a decrease in respiratory sounds on the lung side.

Radiological Investigations and PET-CT

Normal lung graphs are not enough to diagnose mesothelioma. In cases where mesothelioma is suspected and lung thickening or fluid thickening is detected on lung grafts, further investigation is always done.

Computerized tomography MR

As shown in the picture below, thickening areas or fluid collection on the lung gyrus are detected in the computed tomography. The red arrow in the picture points to mesotheliomed areas.

MR is useful to show the tumor in more detail about the diaphragm and heart conditions. If there is doubt, MR examination should be done in computerized tomography. Otherwise MR is not required.

A mesothelioma that lies beneath the diaphragm, extends toward the abdominal region, or has passed the heart membrane passes the third stage.

Detecting the stage of the disease is crucial for the selection of appropriate treatment. For this reason, detailed examinations are essential before selecting appropriate treatment.

The MR image in the adjacent image shows that the mesothelioma did not exceed the diaphragm.

If a lesion in the lung membrane is suspected mesothelioma is suspected, PET-CT is researched to see if this lesion consumes energy. If PET-CT does not have energy consumption (involvement), this lesion is extremely unlikely to be a mesothelioma.

PET-CT is also important to demonstrate whether mesothelioma has spread to other parts of the body.

No treatment of mesothelioma without PET-CT should be initiated, no matter what treatment.

If liquid is available, it is a method used to diagnose mesothelioma of the needle biopsy or thoracoscopic biopsy of malignancy to take a fluid sample with the help of a needle (thoracentesis). Pathology examination should not only identify the mesothelioma, but also the type of mesothelioma.
