to set out essential information about peritoneal metastases,
to provide general knowledge about diagnostic imaging of peritoneal lesions,
to indicate several scoring systems that are used in determining the extent of peritoneal carcinomatosis,
to point out basic facts about various therapeutic options,
to present a concept of a standardized radiology report.
a potential space confined by the parietal and the visceral peritoneum
contains serosal fluid - 50-100ml
the pathways of circulation of the peritoneal fluid explain the propensity of metastases for occupying certain compartments
The fluid accumulates in the most dependent recesses,
the pouch of Douglas in women,
the rectovesical recess in men,
the right paracolic gutter,
the right subhepatic recess (the Morison's pouch),
the upper part of the sigmoid mesocolon and the caecum.

Findings and procedure details
The role of diagnostic imaging
to differentiate a group of patients with extensive carcinomatosis or with unfavorable lesion sites,
who are not amenable to CRS from patients,
in whose case surgical procedures are feasible,
to guide sampling of suspicious sites
to assess the response to chemotherapy
to detect a relapse [5,
an auxiliary modality
poor sensitivity in the visualization of peritoneal,
nodal and parenchymal metastases (69%,
a guiding modality for biopsies [4,
The awareness of the clinical implications of radiology reports in patients with peritoneal metastases may lead to a substantial improvement in report quality.
Each diagnostic imaging study should be meticulously searched for signs of involvement of the surgically critical areas,
that potentially might be a cause of unresectability,
and the overall tumor burden should be estimated.
This might prevent unnecessary surgical interventions and might enable choosing a group of patients that would potentially benefit from neoadjuvant chemotherapy or should be treated with palliative chemotherapy.
