Blunting of the lateral costophrenic angle usually requires about 175 mL but may take as much as 500 mL. Larger pleural effusions opacify portions of the hemithorax and may cause mediastinal shift; effusions 4 L may cause complete opacification of the hemithorax and mediastinal shift to the contralateral.Pleural effusion is the abnormal accumulation of fluid in the pleural space (the area between the two layers of the thin membrane that covers the lungs). Fluid can accumulate in the pleural space as a result of a large number of disorders, including infections, tumors, injuries, heart, kidney, or liver failure, blood clots in the lung blood vessels (pulmonary emboli), and drugs.
This, however, is not always correct and costophrenic angle blunting can be related to other pleural disease, or to underlying lung disease. Lung hyper-expansion can also lead to blunting of the costophrenic angles. This is because the domes of the diaphragm are pushed downwards and so the angle formed is no longer acute.Accumulation of fluid in the pleural space. ○ Caused by: ○ Inflammation. ○ Recent surgery. ○ Radiographic appearance: ○ Blunting of the costophrenic angle.

the costophrenic angles. Initial blurring of vascular structures is seen in the right Initial blurring of vascular structures is seen in the right central region.Costophrenic angle blunting is a radiological finding or diagnosis. Word Costo is used to describe disease related to ribs and phrenic word is used to describe disease close to diaphragm. The acute angle between rib and diaphragm is considered normal when angle is less than 30 degrees and blunt when angle is more than 30 degrees. Angle becomes blunt in patients suffering with pleural effusion.
Distance to the lesion and the puncture angle are calculated electronically. After CT-guided puncture of the lesion and positioning of the laser application system, the patient is transferred to a conventional MR system. First of all a magnetite marker is placed for veriﬁcation of the positioning of the laser application systems. After verifying the correct positioning of the laser.A chest radiograph showed blunting of the left costophrenic angle ( Figure 1A). Chest computed tomography images obtained after therapeu- tic thoracentesis .
The costodiaphragmatic recess, also called the costophrenic recess or phrenicocostal sinus, In anatomy, the costophrenic angles are the places where the diaphragm (-phrenic) meets the ribs (costo-). Each costophrenic angle can normally .Blunting of the costophrenic angles is usually caused by a pleural effusion, as already discussed. Other causes of costophrenic angle blunting include lung disease in the region of the costophrenic angle, and lung hyperexpansion.
