Article Synopsis
- A 75-year-old man with a history of transverse colon cancer surgery presented with retroperitoneal fibrosis (RPF) detected during a routine CT scan, prompting concerns about cancer recurrence or IgG4-related disease (RD).
- Despite normal tumor markers and IgG4 levels, his soluble interleukin 2 receptor (sIL-2R) levels were elevated, indicating unusual immune activity.
- Ultimately, an open biopsy confirmed the presence of IgG4-positive plasma cells, leading to a diagnosis of IgG4-RD RPF, suggesting that elevated sIL-2R and imaging characteristics can help in identifying this condition after colorectal cancer surgery.
