Background
Peritoneal spaces and ligaments are frequently affected by infectious,
inflammatory,
traumatic and neoplastic diseases.
An accurate knowledge of peritoneal anatomy and diseases is essential to provide the diagnosis.
Recognizing the peritoneal anatomy and its imaging findings may assist in the detection and characterization of peritoneal diseases.
In addition it may explain how neoplastic disease and other pathologic processes spread.
The diagnosis of a peritoneal process can be challenging and often different diseases result in a similar spectrum of changes.
Ancillary findings such as local invasion,
presence of ascites or lymphadenopathies,
presence or absence of cystic,
calcific,
or fat densities in addition to clinical history can help the diagnosis.
The recognition of folds and ligaments and potential internal herniation orifices is a cornerstone in the identification of internal hernias.
