X-ray AP and lateral views indicating an intra-abdominal soft tissue density with calcifications, elevating the diaphragms and displacing the bowels to the right and posteriorly; c. Ultrasound images showing a large, complex abdominopelvic focus (9.4 cm in its widest dimension) with calcifications and moderate ascites (in the perihepatic, perisplenic and pelvic areas); d. CT transverse and sagittal views showing an intra-abdominal complex focus with internal septations and calcifications (measuring 10.1 × 13.2 × 8.2 cm), displaced viscerae, and moderate ascites
