A case of acute necrotising pancreatitis, was admitted in our tertiary care centre with complaints of abdominal pain in the epigastric region for 2 days. Pain was associated with vomiting, sore throat and fever on and off. On examination, the patient was tachycardic, and had B/L parotid enlargement with erythema. Systemic examination was insignificant except for mild epigastric tenderness and distension. USG and CECT- abdomen confirmed the necrotising nature of the pancreatitis. The biochemical and serological work-up eventually revealed the final diagnosis of the cause of pancreatitis in the patient. The case is being published in view of the rarity, and the difficulty in diagnosing the condition
