Abstract
The present study was conducted in Chest Department,
Menoufia University Hospital during the period between August 2020
to December 2021. It included 40 patients who fulfilled the selection
criteria & formed the study population.
Aim of the current study was to assess Role of chest ultrasound
in Patients with peripheral thoracic lesions.
The patients were subjected basically to full history taking, full
clinical examination, chest x-ray and CT chest. All patients were
examined by transthoracic ultrasonography.
In cases of pleural effusion, the pleural fluid was aspirated and
sent for chemical, bacteriological and cytological examination to
study the relationship between the sonographic findings and the nature
of pleural fluid. Also sonar guided biopsy was done in indicated
patients. CT guided biopsy, bronchoscopic and thoracoscopic biopsies
were also done whenever indicated.
In the current study the total number of diagnosed cases was 38
patients out of 40 patients who represent the study population. 11
cases out of the 38 patients of the study population were diagnosed by
US guided biopsy, 16 cases were diagnosed by US guided aspiration
and 2 cases were diagnosed by US guided biopsy and aspiration. One
case was diagnosed by CT guided biopsy because the result of US
guided biopsy was non-specific. Bronchoscopic biopsy was done in 2
patients who had central mass. Another 5 cases were diagnosed by
thoracoscopic biopsies because trials of US guided biopsy was failed.
Summary and Conclusion

In the present study, examination of the lung showed that
normal lung was detected in 4 patients with percent 10, collapsed lung
was detected in 19 patients with percent 47.5, lung consolidation was
detected in 5 patients with percent 12.5, lung mass was detected in 10
patients with percent 25, lung nodule was detected in 1 patient with
percent 2.5 and lung abscess in 1 patient with percent 2.5. examination
of the pleura showed that normal pleura was detected in 17 patients
with percent 42.5, diffuse thickening was detected in 13 patients with
percent 32.5, nodular thickening in 8 patients with percent 20, pleural
mass was detected in 2 patients with percent 5 while pleura effusion
was detected in 33 patients with percent 82.5 in which pleural effusion
was echogenic in 26 patients with percent 65, hypoechoic in 2 patients
with percent 5 and anechoic in 5 patients with percent 12.5.
In the present study, pleura effusion was chemically analysied
in 22 patients of the study population. By chemical analysis of the
pleural fluid, 17 of them were found to have exudative pleural
effusion and 5 of them were found to have transudative pleural
effusion.
In this study,total number of studied patients was 40 patient. 38
patients were diagnosed (95%), and 2 patients (5%) were not
diagnosed due to death or discharge before final diagnosis.
In the present study, 15 cases were diagnosed as bronchogenic
carcinoma, 8 cases were diagnosed as pneumonia and parapneumonic
effusion, 6 cases were diagnosed as mesothelioma, 1 case was
diagnosed as lung abscess, 1 case was diagnosed lymphoma, 4 cases
were diagnosed as hepatic hydrothorax, one case was diagnosed as
empyema, one case was diagnosed as epithelial type neoplasm
infiltrating pleura.
Summary and Conclusion

In this study, Transthoracic ultrasound has Sensitivity and
Specificity 83%, 67% respectively. Transthoracic ultrasound shows
97% Predictive value of +ve result and 25% Predictive value of -ve
result. So it is good positive test but not good negative one.
