case_images: CMR imaging of the pericardial cyst (red arrows) displayed in the axial plane. Sequential images (from a-d) highlight the cranial (a) to caudal (d) extent of the cyst. The cyst encases much of the right heart, including (c) the free wall of the RV. No tricuspid regurgitation or caval compression is seen.. RV: right ventricle, CMR: cardiac magnetic resonance

case_images: FIG1
case_images: A large 9x3 cm pericardial cyst was identified, which appeared to be occupying the lateral aspect of the right ventricle and causing minor external compression (Figure 1).
case_images: Panel of intraoperative images. Excellent visualization is afforded with the DaVinci Robotic System (a). Prior to removal, the large multiloculated cyst is seen on the right-hand side (green arrow), closely adherent to the pericardium (white arrow). The phrenic nerve is carefully identified (blue arrow). (b) Bipolar graspers are used to detach the cyst from the rest of the pericardium, and (c) careful cutting away of the bulk of the cyst is performed. This allows insertion (d) of the suction port to aspirate the clear cystic content.

case_images: As per the CMR, the multiloculated cyst was identified above the pericardium and lateral to the right ventricle (Figure 2).
