Objectives:
To show the radiological manifestations of primary pleural tumors.
Patients And Methods:
we carried out a retrospective analysis of radiological findings in 62 patients with primary malignant tumor of pleura.
Results:
Study included 39 male and 23 female patients. Malignant tumors were present in 92.7% of the patients and benign ones in 7.2%. The most common malignant tumor was mesothelioma (85.4%), and solitary fibrous tumor prevailed among benign tumors (9.7%). Diffuse malignant mesothelioma manifested on computed tomography (CT) as a pleural thickening and effusion in 67.4% of the patients, tumors and effusion in 11.7%, and only as an effusion in 9.8% cases. Thickening of the pleura appeared diffuse in 54% of patients and most often it had nodular pattern. Both localized malignant and all benign tumors presented as tumor-like changes with the signs of necrosis in 50%.
Conclusion:
The imaging methods have a key role in the diagnosis of pleural tumors. CT shows different morphologic features of pleural lesions that have been established as a useful tool for differentiating malignant from benign disease. However, magnetic resonance is preferred imaging method for assessing the extent and resectability of pleural tumors.

A pleural effusion is the abnormal collection of fluid between the parietal and visceral pleura layers of tissue that form the lining of the lungs and chest cavity. It can occur independently or due to surrounding parenchymal diseases, such as infection, malignancy, or inflammatory conditions.

Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...
