Abstract

PURPOSE: To investigate the incidence and significance of localized fluid collection in the hepatic bare area re-sulting from blunt abdominal trauma in children. Materias and Methods:We retrospectively reviewed the CT scans and medical records of eighty children with blunt abdominal trauma and evaluated the incidence of fluid collection in the hepatic bare area. The findings were correlated with the presence of injury to adjacent organs. RESULTS: Fluid collection in the hepatic bare area was noted in 23 of 80 patients (28.7%). Associated organ in-juries included liver laceration (17/23), contusion of the right hemidiaphragm (7/23), right adrenal injury (5/23), and right renal injury (5/23). In one patient, organic injury was not detected in spite of fluid collection in the hepatic bare area. Eight of 23 patients (34.8%) showed fluid collection in this area, but not intraperitoneally. CONCLUSION: Fluid collection in the hepatic bare area after blunt abdominal trauma was noted in about 30% of patients and was frequently accompanied by injury to adjacent organs. Since right hemidiaphragmatic contusion associated with fluid collection in the bare area was a not uncommon CT finding, close observation of the condition is warranted.
