Caption: Figure 1: (a) Preoperative chest X-ray shows right sided obliteration of costophrenic angle and displaced right lung.
Chest X ray (PA view) showing in-homogeneous opacities in right upper lope, linear fibrotic opacities in right middle lobe and blunting of right costophrenic angle.
Blunting of a costophrenic angle is the classic sign for pleural effusion.
On the other hand as little as 50ml of pleural fluid may cause blunting of the posterior costophrenic angle on a lateral chest radiograph (Light 2005).
The chest radiograph showed some subtle consolidation at the left costophrenic angle.
The EKG again showed abnormalities, including a nonspecific T-wave abnormality, as did the chest radiograph (moderate cardiomegaly, tortuous aorta, mild prominence of the pulmonary vasculature without evidence of congestive failure, and small left pleural effusion or slight blunting of the left lateral costophrenic angle).
Initial chest x-ray showed air-space shadowing of the right upper and middle lobes of the lung, as well as blunting of the fight costophrenic angle. Blood tests gave the following results: leukocyte count 7.42 x [10.sup.9]/L, neutrophil count 6.53 x 109/L, platelet count 287 x 109/L, hemoglobin level 8.6 g/dL, prothrombin time 15.3 s, and activated partial thromboplastin time 28.7 s.
Chest radiograph revealed a homogeneous mass lesion in the left lower lung field with obliteration of the costophrenic angle. Computed tomography scans of the chest disclosed a huge mass over the left lower thorax and upper abdomen with compression of the heart and shift of the esophagus and descending aorta to the midline.
Preliminary routine investigations were normal and the patient underwent chest radiograph, posteroanterior view in erect position, which revealed blunted right costophrenic angle with elevated right hemidiaphragm.
X-Ray Chest was normal except obliteration of right costophrenic angle.
