A septum-like structure of the gallbladder in acute viral hepatitis: CT demonstration

We present two patients with a septum-like structure of the gallbladder on CT. The patients were hospitalized with acute viral hepatitis. CT performed within a week from the onset of symptoms demonstrated a high density linear structure in the gallbladder mimicking a septum. This structure seemed to be produced by a marked thickening of the gallbladder wall. It disappeared during the clinical recovery.
