Background: Benign multicystic peritoneal mesothelioma is a multiloculated cystic mass which originates from the peritoneum. This rare tumor is usually seen in women of childbearing age and has a high recurrence rate after surgery.
Case presentation: We present two benign multicystic peritoneal mesothelioma cases with different imaging modalities, which were also pathologically proven.
Conclusion: The imaging features which may be diagnostic should be well known as there are very few reports regarding this entity.
