PERITONEAL INCLUSION CYSTS Introduction

PERITONEAL INCLUSION CYSTS Introduction

These are benign cysts lined by peritoneal mesothelium. They can arise at any location of the peritoneum, in continuity with the surface of either parietal or visceral peritoneum. They can gradually expand and rarely rupture. Most are asymptomatic and are identified incidentally on cross-sectional imaging for other indications. There is a loose association with ovarian malignancy and thus MRI evaluation of the ovaries is advisable in the premenopausal context. If symptomatic an inclusion cyst may be drained under imaging control, deroofed or excised. Recurrent rates are high.
