Differential diagnosis of chylothorax in a patient on parenteral nutrition: a case report.

Parenteral nutrition (PN) is widely used when enteral feeding is contraindicated or not possible in patients who are malnourished or at risk of malnutrition, but it is not without complications. We describe the rare complication of PN-related chylothorax that can lead to extensive investigations if not picked up early with clinical suspicion and simple biochemical tests.
