title: Flattened fundus sign of the septate gallbladder.
abstract: The fundus of a normal gallbladder is rounded. Any deviation from this configuration should prompt a search for the nonfilled segment of a septate gallbladder. Three illustrative cases are presented in which the initial observation of a flat fundus led to further evaluation and visualization of the remaining portion of a septate gallbladder.
