Radiologic findings in tsunami trauma: experience with 225 patients injured in the 2004 tsunami.

The objective of this study was to determine the spectrum of radiographic findings, frequency, and type of injuries in tsunami victims. From December 2004 to May 2005, all tsunami victims admitted to our hospital were retrospectively identified by a search of medical records. Patients who received radiologic examinations were reviewed for their radiographic findings. The authors identified 225 tsunami victims. One hundred eight victims received radiologic evaluations on admission that included 350 plain radiographs, 19 ultrasound exams, 18 computed tomography (CT) scans and 3 magnetic resonance imaging (MRI) scans. Overall positivity rate was 48% (187/390). Most common trauma involved musculoskeleton (102/187, 54.5%). Retained foreign bodies in soft tissues, pneumonia/aspiration, and tsunami sinusitis were found in 22, 28, and 31 patients (9.8, 12.4, and 13.8%), respectively. These were unique findings in tsunami trauma. Imaging played an important role in detection of these abnormalities.
