Labs associated with pancreatic hydrothorax include which findings?

• A. Elevated serum amylase and lipase, elevated CRP
• B. Hyperkalemia
• C. Hypocalcemia
• D. Decreased liver enzymes

Answer: (A)

Pancreatic hydrothorax happens when pancreatic fluid leaks into the pleural space due to a ductal disruption, usually in the setting of pancreatitis. Because the process involves pancreatic injury, the body’s response includes elevated pancreatic enzymes and inflammatory markers. Therefore, elevated serum amylase and lipase reflect pancreatic injury, and CRP rises as part of the inflammatory reaction. This combination aligns with the underlying disease process and is the most consistent lab pattern for this condition. Hyperkalemia is not a typical feature of pancreatitis or pancreatic hydrothorax; hypocalcemia can occur in pancreatitis but is not specific to hydrothorax, and decreased liver enzymes do not fit the expected inflammatory and pancreatic injury profile.
