Extensive peritoneal calcification and small intestinal perforation in a peritoneal dialysis patient: a case report.

A 56-year-old woman was maintained on continuous ambulatory peritoneal dialysis (PD) for 12 years. The patient presented to our hospital with chief complaints of intermittent abdominal pain and frequent loose stool. Plain radiograph of abdomen revealed extensive peritoneal calcification. Computed tomography confirmed the extensive peritoneal calcification and revealed a large right ovarian cyst. Torsion of the right ovarian cyst was suspected. Right oophorectomy was performed. Small intestinal perforation developed 37 days after the operation. The patient expired because of peritonitis and sepsis. Extensive peritoneal calcification is a rare and serious complication after long-term PD. Intestinal perforation is a rare complication of PD. Pathognomic signs of imaging studies can be important in early diagnosis and treatment.
