CRP and pancreatitis: Magnetic resonance imaging (MRI) revealed a cyst with heterogeneous high signal intensity on T1-weighted sequences and predominantly low signal intensity on T2-weighted sequences (Figure 1C). These imaging findings and an elevated serum C-reactive protein (CRP) level of 6.88 mg/dL (reference range: <0.3 mg/dL) suggested a pancreatic pseudocyst likely caused by pancreatitis.
