RE: Metastasis of Gallbladder Adenocarcinoma to Bauhin's Valve: An Extremely Rare Cause of Intestinal Obstruction

We would like to offer our experience with an unreported type of metastasis to Bauhin’s valve deriving from gallbladder adenocarcinoma as well as determining intestinal obstruction. An 83-year-old woman presented with intestinal obstruction of 2 days duration. Contrast-enhanced CT scan of the abdomen documented distended small-bowel loops and a 31 x 23 mm lesion in the right iliac fossa with distal ileal and cecal involvement (Fig. 1); additionally, a centimetric metastasis was observed in segment IV of the liver. An initial conservative management resulted successful permitting elective colonoscopy to visualize a polypoid lesion at the Bauhin’s valve (Fig. 2); biopsies were noncontributory. At this point, we decided to perform a right colectomy associated with an ultrasound-guided
