    The costodiaphragmatic recess, also called the costophrenic recess or phrenicocostal sinus, Each costophrenic angle can normally be seen as on chest x-ray as a sharply-pointed, downward indentation (dark) between each. costophrenic angle) with radiolucency along costophrenic sulcus an unusually sharp definition of the anterior diaphragmatic surface due to.

    Contrast-enhanced axial image of CT chest shows central embolus with peripheral contrast in a right pulmonary artery branch white arrow producing the radiologic sign, polo mint sign.

    Obstructive pathologies comprise benign tumors like hamartoma, lipoma, etc. Silhouette sign This sign is present when an intra-thoracic lesion touches the border of the heart, aorta, or diaphragm and that border is obliterated on the X-ray [Figure 21a — c ]. Once visualized, one should always look for other signs of pneumothorax in cases of major trauma, neonates, and ICU patients to avoid errors.
