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

Area of Science:

• Nephrology
• Radiology
• Infectious Diseases

Background:

• Peritoneal dialysis (PD) patients are susceptible to serious peritoneal complications.
• Two known PD-related pathologies include ascites with septations and encapsulating peritoneal sclerosis.
• Abdominal CT imaging aids in diagnosing these conditions.

Observation:

• A case study of a PD patient with relapsing Pseudomonas aeruginosa peritonitis is presented.
• The patient developed a unique, single, thick-walled fluid collection.
• This radiological finding evolved over time, resembling a "rind" formation.

Findings:

• The observed fluid collection exhibited distinct features differentiating it from ascites and encapsulating peritoneal sclerosis.
• This represents a previously undescribed intra-abdominal pathology in PD patients.
• The evolution of the collection was tracked via serial abdominal CT imaging.

Implications:

• Pseudomonas aeruginosa peritonitis can lead to a distinct "rind" formation, similar to pleural or peritoneal empyemas.
• This finding expands the spectrum of known peritoneal complications in PD patients.
• Recognition of this entity is crucial for accurate diagnosis and management of PD-related peritonitis.
