Microscopic evaluation of giant peritoneal loose body: A case report

Figure 1 Abdominal computed tomography. A: Plain abdominal computed tomography (CT) shows a 5.0 cm × 4.2 cm cystic-solid mass within the left pelvic margin with well-defined borders; B: Contrast-enhanced abdominal CT shows no obvious enhancement or significant blood supply within the mass.

Figure 2 Lesion morphology. A: Morphology of the lesion under laparoscopy; B: The lesion was approximately 4.5 centimeters × 5.0 centimeters in size, with a smooth surface, a consistent, solid texture, and a distinct border; C: The lesion could be separated into three layers, with visible gravel-like material in the center; D: Hematoxylin and eosin staining of the lesion.
