Figure 10c. Ventricular perforation in a 35-year-old man after percutaneous pericardial drainage for exudative pericarditis. (a) Axial CT image shows an extensive pericardial effusion with bilateral compression of the cardiac chambers, bilateral pulmonary consolidation, and pleural effusions. Only parts of the percutaneous drainage tube can be seen. (b, c) Coronal (b) and sagittal (c) thin-slab MIP images show the course of the tube, which makes a loop in the pericardial cavity and perforates the right ventricle (arrowhead in c). The end of the tube makes contact with the interventricular septum. (d) Sagittal volume rendered image shows the entire course of the tube (arrowheads). The end of the tube appears to perforate the interventricular septum. This wrong impression is caused by the large slab thickness used to depict the entire course of the tube.
