Figure 7b. HD of the liver with involvement of the diaphragm and thoracic cavity in a 54-year-old man. The patient lived in an endemic region and had previously undergone surgery for hepatic HD. (a) Axial contrast-enhanced CT scan through the dome of the liver shows a hypoattenuating lesion that originates from the posterior segment of the right hepatic lobe and has grown through the diaphragm to the lung. (b) Corresponding axial T2-weighted MR image shows the lesion with a multivesicular appearance, transdiaphragmatic growth, and protrusion into the right lower basal lung segment.
