Blunt diaphragmatic lesions: Imaging findings and pitfalls

Figure 11 Computed tomography findings in blunt diaphragmatic lesions - hump and band sign. These 3 mm thick multiplanar axial (A) and coronal (B) reconstructions show a hypodense band that crosses the liver parenchyma in the site where it crosses the ruptured diaphragm (arrows), whereas the liver dome expands above it. This alteration represents the so-called “hump and band sign” (a).
