An intra-abdominal abscess or "rind" as a consequence of peritoneal dialysis-associated pseudomonas peritonitis

Abstract

Background: Abdominal CT imaging has defined characteristics of two pathological entities specific to peritoneal dialysis patients. Both are associated with serious peritoneal complications. One is comprised of ascites accompanied by septation and loculated fluid pockets as a complication of bacterial peritonitis. The other is the syndrome of encapsulating peritoneal sclerosis. We present the evolution of a single, thick-walled fluid collection as a consequence of relapsing Pseudomonas aeruginosa peritonitis. The entity had distinctive features differing from either of the two previously described entities, and to our knowledge, has not been described previously. Our patient’s radiological evolution resembled the formation of a pleural or peritoneal “rind.” Conclusion: Peritonitis, as a result of Pseudomonas aeruginosa, may lead to “rind” formation as described with empyemas and is distinct from previously described intra-abdominal pathologies in peritoneal dialysis patients.

Persistent Abdominal Pain following Peritoneal Dialysis Catheter Removal for Peritonitis

“…Studies have shown that peritoneal dialysis can be successfully resumed in patients after early catheter removal (1). Development of an intra-abdominal abscess is a rare complication of peritonitis and has been seldom reported in the literature (4,5). Abscess formation specifically after catheter removal is uncommon and has been reported in small case reports (4,5).…”

“…Development of an intra-abdominal abscess is a rare complication of peritonitis and has been seldom reported in the literature (4,5). Abscess formation specifically after catheter removal is uncommon and has been reported in small case reports (4,5). Clinical findings of persistent fever, abdominal pain, and tenderness along with leukocytosis are suggestive of abscess development and necessitate further radiographic investigation.…”
