Morison's pouch: anatomical review and evaluation of pathologies and disease spread on cross-sectional imaging

Abstract

The peritoneum is a complex structure. Having a better understanding of this complex anatomy will enable the radiologist to accurately assess and diagnose the wide range of intra-abdominal pathologies. In this article, we review the anatomy, boundaries, and connections of Morison's pouch. In addition, we discuss the incidence and development of common pathological conditions within Morison's pouch and the role of multiple imaging modalities in assessment and diagnosis of these conditions.
