Recognition of a Sausage-Shaped Pancreas on Non-contrast Computed Tomography as an Early Clue to Type 2 Autoimmune Pancreatitis in a Young Adult.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Autoimmune pancreatitis (AIP) is an uncommon form of chronic pancreatitis characterized by immune-mediated inflammation and a dramatic response to corticosteroid therapy. Two distinct subtypes are recognized, each with differing clinical, serological, and histopathologic profiles. Type 2 AIP predominantly affects younger patients and is not associated with elevated serum immunoglobulin G4 levels, making the diagnosis particularly challenging. We report a 28‑year‑old man who presented with recurrent epigastric pain and elevated serum lipase. Non‑contrast computed tomography (CT) revealed no peripancreatic fat stranding or fluid collection; however, subtle loss of the normal pancreatic lobular architecture produced a sausage‑shaped configuration of the pancreas. Further evaluation with magnetic resonance cholangiopancreatography demonstrated diffuse irregular narrowing of the main pancreatic duct. Endoscopic ultrasound‑guided biopsy confirmed idiopathic duct‑centric pancreatitis with granulocytic epithelial lesions, consistent with type 2 AIP. Complete clinical, biochemical, and radiologic resolution was achieved following corticosteroid therapy. This case highlights that a sausage‑shaped pancreas on non‑contrast CT, even in the absence of typical inflammatory features, should prompt consideration of AIP in young adults.
