Based on the scan description:

Prominent structure below liver in region of gallbladder, tortuous and distended (0.84 × 1.77 cm), neonate 38+0, clinically well, abdomen full

Top 3 Differentials

1. Distended Gallbladder

   • Most likely given location directly beneath liver

   • Can be physiologically distended in neonates

   • May appear elongated/tortuous

   • LFTs largely normal (ALT normal; bili/ALP pending due to haemolysis)

2. Choledochal Cyst

   • Cystic structure near porta hepatis

   • Can present as cystic mass in RUQ

   • May not yet have abnormal LFTs

   • Important to exclude due to risk of obstruction and cholangitis

3. Dilated Bowel Loop (e.g., proximal duodenum)

   • Can mimic cystic RUQ structure

   • More likely if abdomen described as full

   • Would assess for feeding intolerance, bilious vomiting

If you’d like, I can also provide:

• Red flag features to differentiate them

• A neonatal-specific differential ranking

• Or how to phrase this in a consultant handover note
