1. ANATOMY Retroperitoneum is the portion of abdomen and pelvis located outside the peritoneal cavity and bounded anteriorly by parietal peritoneal fold ( Fig. 1 ). 1.1 Abdominal retroperitoneal space Meyer’s and colleagues tricompartmental theory divides the abdominal retroperitoneum into the following spaces: ( Fig. 2 ): - Anterior pararenal space (APS) - Perirenal space (PS) - Posterior pararenal space (PPS) Subsequent research updated the tricompartmental theory through the demonstration...
Findings and procedure details
Retroperitoneal diseases are typically an emergency condition that require an early diagnosis to ensure an optimal management.
As clinical symptoms are frequently vague and mild,
and local examination is not easily accessible by clinicians,
an early diagnosis may be hard. Affected patients may show critical predisposing factors (e.g.
chronic renal failure) that decrease the prognosis in terms of overall survival. Retroperitoneal diseases may manifest in...
Identification of pathologic involvement of retroperitoneum requires an optimal knowledge of its complex anatomy.
CT-imaging permits to evaluate the presence of pneumoretroperitoneum and associated findings of fluid and inflammatory collections and their extension.
the radiologist give an important support to clinicians in the establishment of the diagnosis and the better management of the underlying causes.
