ABSTRACT
Congenital anomalies of the gallbladder (GB) correspond to the ultimate manifestation of the wide range of anatomical variations that may affect the GB. Anomalies may be numerical: duplication, accessory GB, and, rarely, agenesis. Anomalies of position are more common: ectopic GB, floating or wandering GB. Morphological anomalies (septations) are the most common GB anomalies. Most of these anomalies may result in pitfalls at US imaging.

The authors report the results from the ultrasonographic exploration of the gallbladder performed on 1823 patients. They found morphologic variations and abnormalities in more than 33% of gallbladders, topographic ones in about 3.5% of observations and only 3 cases of real duplication of the gallbladder. Folds and septa may induce traps during echographic examination.

The authors report a new case of leiomyosarcoma of the duodenum. The exoluminal growth and the volume of this tumor explain the difficulties of the imaging methods diagnostic. Computed tomography, magnetic resonance imaging and angiography were not sufficient to determine the origin of the tumor. Surgical exposure itself was not conclusive and only pathology provided the definitive diagnosis. We think that endoscopic ultrasonography should be indicated in these submucosal tumors of the duodenum to differentiate them from pancreatic neoplasms.
