Partial multiseptate gallbladder: sonographic appearance.

Multiseptate gallbladder, a rare congenital anomaly, is characterized by the presence of multiple thin septa dividing the gallbladder lumen into various sized chambers, often with a honeycomb appearance. In nearly all cases described previously, the entire gallbladder lumen was traversed by the septa. We describe three children, ages 3, 9, and 16 years, with sonographic features of multiseptate gallbladder, in which the septa were confined to the body and neck of the gallbladder in two, and to the fundus in one. The CT features of the anomaly also are described in one patient.
