Peritoneal carcinomatosis (PC) is a term to describe the distant spread (metastatic) of the primary tumor to the peritoneal cavity. PC is a late-stage manifestation of various gastrointestinal malignancies in general and affects the ovaries, which is characterized as tumor deposits involving the surface of the peritoneal wall. If no primary signs are found, the primary diagnosis can be considered from the peritoneum itself. PC itself can be found incidentally on imaging, which can be seen on computed tomography examination, but in some mimicking images making it difficult to make a diagnosis, it is necessary to correlate it with the histopathological results.
