Sixteen months prior the patient had an excisional biopsy and a right neck dissection for a right neck mass, however, no malignancy was detected. Due to the increased activity in the right upper quadrant, the patient underwent an ultrasound, which demonstrated a possible mass in the wall of the gallbladder. Subsequent MRI demonstrated a low-level enhancing gallbladder neck mass. A cholecystectomy was performed.images/2.7.06.PIcase3a.jpgimages/2.7.06.PIcase3b.jpgimages/2.7.06.PIcase3c.jpgimages/2.7.06.PIcase3d.jpgimages/2.7.06.PIcase3e.jpgSmall cell carcinomaWell differentiated neuroendocrine tumor (carcinoid)AdenocarcinomaAdenomyoma Loading...
