#WetreadCoW Case 11 Answer: Pseudomyxoma Peritonei

👍 on the gifs everyone! ImageImage
Pseudomyxoma Peritonei

Source: mucinous tumor of appendix (#1), colon, stomach, pancreas, urachus, ovary

Rupture➡️ mucin & neoplastic cells into the peritoneum ➡️ diffuse peritoneal spread of malignancy and increasing abdominal distention

US - echogenic peritoneal masses
CT - low/simple fluid locules w mass effect
+/- ring calcs
➡️ scalloping of organ surfaces
- often with curvilinear Calcs
- centrally displaced small bowel
MR - low T1, high T2 (follows water) +/- enhance
Pseudomyxoma Peritonei

Complication: fibrosis + adhesions➡️recurrent bowel obstructions (can be fatal)
