We present a case where low attenuation gallstones are visible on CT only on delayed imaging secondary to gallbladder opacification from vicarious excretion of contrast. We discuss heterotopic accumulation of contrast in the gallbladder and its potential diagnostic utilization in the detection of occult pathology.

Vicarious excretion of tracer and contrast media is a known phenomenon and is not fully understood [1,2]. We report a case of unexpected vicarious excretion of Tc-pyrophosphate in the gallbladder seen on a scan performed to evaluate suspected cardiac amyloidosis, which is the first report of this phenomenon to the best of our knowledge.

A 23-year-old otherwise well male, with right ureteric stent placed electively for a 9-mm symptomatic pelviureteric junction stone underwent a right ureteropyeloscopy, retrograde pyelogram laser lithotripsy and stent exchange for stone clearance. The procedure was uncomplicated. Following stent removal on day 2, the patient developed acute right lower quadrant pain, which was investigated with non-contrast CT abdomen.

An iodinated contrast medium (CM) is generally excreted into the urinary tract within 3 min after administration. However, some cases present a persistent kidney nephrogram several hours after administration of CM. This phenomenon seems to be associated with the development and acceleration of contrast-induced nephropathy (CIN).

Intravenous use of contrast medium (CM), which may cause kidney dysfunction, is admissible for hemodialysis patients because of the efficient removal by hemodialysis. We herein report a 61-year-old woman on hemodialysis who suffered from cholecystitis and cholangitis after large-volume CM administration during continuous renal replacement therapy. After catheter ablation, she developed life-threatening retroperitoneal hemorrhage, which led to the use of 500 mL CM for 5 consecutive days.
