Three days later, further testing to identify the cause of leukocytosis and source of infection included Indium WBC whole-body scan which showed increased accumulation of 111 in-leukocytes within the gallbladder wall suggestive of hyperemia/inflammatory changes in the pericholecystic region (Figure 1).
Computed tomography of the abdomen with oral contrast showing the gallbladder markedly distended (long arrow). Air bubbles project over the region of gallbladder neck are seen, suggestive of infection with gas-producing organism (short arrows).
