This report emphasizes the need for repeat Focused Assessment with Sonography for Trauma (FAST) and abdominal computed tomography (CT) if a BAT patient's condition persists or worsens. After initial negative FAST and abdominal CT findings, it is recommended that BAT patients with suspected intraabdominal injury should receive repeat examination in an optimal time. We report a patient who sustained duodenal perforation following BAT diagnosed by repeat ultrasound examination and abdominal CT scan.4enjournal article
