Ultrasonographic study (transverse plane) performed at the level of the fifth intercostal space of the right ventral thoracic wall. The right middle lobe (RmL) has sharp margins, is small in size, atelectatic and retracted medially. The right caudal lobe (RCdL) is partially aerated. Lateral to both of these lobes, along the thoracic wall, there is a mass in the right caudal hemithorax, with rounded margins, characterised by a liver-like echogenic tip and multiple gas bubbles reverberating in its central portion (arrow heads). This finding confirmed the corresponding vesicular gas pattern observed in the radiographs. This mass is the right cranial lung lobe (RCrL) (long arrow). An anechoic unilateral mild pleural effusion (PE) surrounds the lung lobes. (L: lateral; M: medial; Cd: caudal; Cr cranial.).
