CT
No intravenous contrast is given due to poor renal function.
1 cm calculus is noted at the neck of the gallbladder. Small amount of stranding is seen around the gallbladder. No pericholecystic fluid.
No intra-abdominal collection. No intraperitoneal free gas or fluid.
Rounded 1.5 cm hypodense lesion is seen within hepatic segment IVb, immediately adjacent to the gallbladder fossa. This may represent an area of fatty liver.
5 mm left renal hyperdense lesion. Small left nephrolithiasis. Large and small bowel are within normal limits.
Bilateral lower lobe atelectasis. No suspicious osseous lesion.
Conclusion
- Cholecystitis with a stone impacted at the neck.
- No intra-abdominal collection.
- The hypodense hepatic lesion should be further assessed on ultrasound.
