It serves as a conduit for the spread of various pathological processes, including gas and fluid collections, inflammation, infections, and neoplastic conditions. Peritoneal carcinomatosis is the most common and well-known pathology involving the peritoneum, typically resulting from the dissemination of gastrointestinal and pelvic malignancies. However, numerous benign and malignant peritoneal diseases can mimic the imaging appearance of peritoneal carcinomatosis. The aim of this review is to revisit the anatomy of peritoneal compartments and elucidate the patterns of peritoneal disease spread. Emphasis is placed on identifying the distinctive imaging features of both neoplastic and non-neoplastic peritoneal diseases that differ from peritoneal carcinomatosis.<\/jats:p>","DOI":"10.3390\/diagnostics15091163","type":"journal-article","created":{"date-parts":[[2025,5,4]],"date-time":"2025-05-04T20:09:14Z","timestamp":1746389354000},"page":"1163","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["The Many Faces of the Angry Peritoneum"],"prefix":"10.3390","volume":"15","author":[{"given":"Maria Chiara","family":"Ambrosetti","sequence":"first","affiliation":[{"name":"Radiology Unit, Department of Pathology and Diagnostics, Azienda Ospedaliera Universitaria Integrata of Verona, 37126 Verona, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Matilde","family":"Bariani","sequence":"additional","affiliation":[{"name":"Radiology Unit, Department of Pathology and Diagnostics, Azienda Ospedaliera Universitaria Integrata of Verona, 37126 Verona, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5059-3305","authenticated-orcid":false,"given":"Giulia Angela","family":"Zamboni","sequence":"additional","affiliation":[{"name":"Institute of Radiology, Department of Diagnostics and Public Health, Policlinico GB Rossi, University of Verona, 37134 Verona, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3465-0151","authenticated-orcid":false,"given":"Riccardo","family":"Valletta","sequence":"additional","affiliation":[{"name":"Department of Radiology, Hospital of Bolzano (SABES-ASDAA), Teaching Hospital of Paracelsus Medical University (PMU), 39100 Bolzano, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4477-8944","authenticated-orcid":false,"given":"Matteo","family":"Bonatti","sequence":"additional","affiliation":[{"name":"Department of Radiology, Hospital of Bolzano (SABES-ASDAA), Teaching Hospital of Paracelsus Medical University (PMU), 39100 Bolzano, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,5,3]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"2710","DOI":"10.1007\/s00261-015-0429-5","article-title":"The subperitoneal space and peritoneal cavity: Basic concepts","volume":"40","author":"Pannu","year":"2015","journal-title":"Abdom.
