Benign multicystic peritoneal mesothelioma status post multiple surgeries. ABDOMEN:LIVER, BILIARY TRACT: The liver is normal in morphology size signal intensity and enhancement without a focal lesion biliary ductal dilatation or vascular abnormality. Normally distended gallbladder.SPLEEN: The spleen is normal in size and morphology without a focal lesion.PANCREAS: No significant abnormality noted.ADRENAL GLANDS: No significant abnormality noted.KIDNEYS, URETERS: No significant abnormality noted.RETROPERITONEUM, LYMPH NODES: No significant abnormality noted.BOWEL, MESENTERY: No free fluid or loculated fluid collection in the upper abdomen. No evidence of bowel obstruction or inflammation.BONES, SOFT TISSUES: Midline abdominal wall surgical changes without complication.OTHER: No significant abnormality noted.PELVIS:UTERUS, ADNEXA: Thick-walled peripherally enhancing right adnexal region cystic lesion measuring 5.3 x 4.8 cm. BLADDER: No significant abnormality noted.LYMPH NODES: No significant abnormality noted.BOWEL, MESENTERY: There is a small volume of septated cystic lesion with thin septation in the deep pelvis measuring up to 4.2 x 3.1 cm axially and 6.1 x 2.4 cm in the sagittal plane associated with thin septations. There is also mild smooth peritoneal surface thickening anteriorly in the left hemi-pelvis. BONES, SOFT TISSUES: No significant abnormality noted.OTHER: No significant abnormality noted.
Complex right adnexal region cystic lesion and septated cystic lesion with septations in the deep pelvis, findings suspicious for disease, given the patient's history of multicystic peritoneal mesothelioma and a similar appearance on prior studies.
