Abstract:
Patients with autosomal dominant polycystic kidney disease (ADPKD) usually have extrarenal manifestations. We report the case of a 53-year-old man with ADPKD who presented with a retroperitoneal abscess of the left side after undergoing bilateral nephrectomy for a cyst that had repeatedly bled for 1 year. The abscess recurred despite drainage with a pig-tail catheter and antibiotic treatment. Fistulography with injection of diluted contrast medium via the pig-tail catheter showed an accumulation of contrast medium in the descending colon, which indicated a fistula between the abscess and the descending colon. A portion of the descending colon was resected, and multiple diverticulitis with 1 perforation in the resected specimen was observed. The findings support a diagnosis of retroperitoneal abscess caused by a perforated diverticulum---an extrarenal manifestation of ADPKD.

Inflammatory Bowel Disease I: Ulcerative Colitis
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...
Inflammatory Bowel Disease II: Crohn's Disease
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by transmural...
