Abstract
US is a safe and easy imaging modality. It uses no ionising radiation or IV contrast material, needs minimal patient cooperation, has bedside availability, and can be performed while the patient is sitting or recumbent. It is less expensive and less time consuming than C.T.The aim of this work is to identify the role of ultrasound in identification and evaluation of pleural abnormalities.
The study was carried out on 98 patients,45(45.9%)males and 53(54%) females their ages ranged from 7 to 75 years old with mean age of 35.5 years.
They were all complaining of medical history suggestive of pleural disease or chest x-ray opacities.
All patients were examined by ultrasound in Radio-diagnosis Department, Menoufiya University hospital.
Out of 98 patients included in this study, 79 patients (80.6%) were found to have pleural effusion and 19 patients (19.3%) were found to have pleural masses.
Pleural lesion was bilateral in 27 cases (27.5%), on the left side in 34 (34.6%) patients and on the right side in 37(37.7%) patients.
Concerning the main cause of pleural effusion was infection 25(31.6%) cases, followed by heart failure 20 (25.3%) cases and the least cause was trauma 7 (8.8%) cases. Concerning masses the main cause was metastatic masses 10 (52.6%) cases ,followed by malignant mesothelioma 8 (42.1%) cases and the least cause was localized fibrous tumour 1(5.2%) case.
