Obliteration of Costophrenic Angte in a Plain X - Ray Chest

Abstract

Obliteration of Costophrenicangle can be a pleural effusion in a majority of cases but other causes of mediastinal masses, aortic aneurysm, postpneumonectomy, lung and pleural masses and consolidation and collapse of the lung can cause shadows mimicking pleural effusion. It is always essential to take the help of lateral and decubitus films, ultrasonography of chest and CT scan chest to come to a proper diagnosis. Inadvertent pleural aspiration basing on chest x-ray PA alone can have disastrous consequences
