ABSTRACT

HISTORY: This was a 40 year old woman with RUQ pain and fever. STUDY: This is a HEPATOBILIARY SCAN utilizing 5.48 mCi of Tc99m mebrofenin (Choletec) injected intravenously. Anterior images of the upper abdomen were obtained every five minutes for 60 minutes. After this, 3.6 mg of Morphine was administered, IV. Following this, multiple anterior images of the upper abdomen were obtained every 5 minutes for 35 minutes. Additionally, right lateral projections were obtained 30 and 60 minutes after the Morphine was introduced. FINDINGS: The liver shows good parenchymal uptake with clearance of the blood pool activity. Excretion is seen into the biliary radicles by 10 minutes. The GB is not visualized. The SB activity is noted by 30 minutes. A focal region of increased radiopharmaceutical uptake is noted in the region of the cystic duct, consistent with the "cystic duct sign". IMPRESSION: Nonvisualization of the GB, with a positive "cystic duct sign", consistent with acute cholecystitis. COMMENTS: The "cystic duct sign" is a sign that has been described in acute cholecystitis. A small nubbin of activity is seen in the cystic duct proximal to the site of obstruction. It is seen between the ballbladder fossa and the comon hepatic duct. REFERENCE: Mettler F.A., Guiberteau M.J., Essentials of Nuclear Medicine, W.B. Saunders Co., 1998. (Page 265)
