Idiopathic retroperitoneal fibrosis presented as abdominal discomfort and low back pain(IgG4-related disease)

摘要

We presented a 45 year-old male patient in a hospital, who had low back pain and non-specific abdominal discomfort for duration of 2 weeks. Abdominal?Computed Tomography?(CT) showed retroperitoneal Para aortic mass at lower aortic roots before bifurcation and elevated C-RP. Unfortunately, the patient refused to do biopsy, and has a history of amlodipine usage with a very high suspicion of idiopathic retroperitoneal fibrosis (IgG4-related disease).
