CASE HISTORY
An 86-year-old woman presented to our hospital with a chief complaint of
epigastric pain. She had undergone ileocecal resection for ascending
colon cancer 10 years previously (pT2N0M0StageI; TNM classification
8th ed.), and no recurrence was reported. In June
2022, she visited her local doctor, who referred her to our hospital
after finding an encapsulated fluid retention and scattered small
nodules in the abdominal cavity on computed tomography (Figure 1).
