Post-traumatic intrasplenic pseudoaneurysms are very rare in children. Since pseudoaneurysms may expand a splenic hematoma and cause delayed splenic rupture, early diagnosis and treatment are crucial. In this report, we describe the case of a 12-year-old boy with a delayed splenic rupture caused by a splenic hematoma containing 2 pseudoaneurysms. Abdominal sonography showed free intraperitoneal fluid and a mildly enlarged spleen with a large heterogeneous area occupying the upper half of the organ. Two anechoic lesions (15 and 4 mm) were seen inside the hematoma near the splenic hilum. Color Doppler sonography demonstrated turbulent arterial flow within the lesions, suggesting pseudoaneurysms. On CT, the lesions enhanced simultaneously with the splenic artery in the arterial phase of contrast enhancement. CT also showed an intrasplenic arterial branch leading to the larger of the 2 pseudoaneurysms.
INTRODUCTION: A prospective analysis was done to determine the frequency of therapy relevance of abdominal computed tomography (CT) in multiple trauma patients in comparison to abdominal ultrasound (US). METHODS: We recorded all multiple trauma patients in the emergency room (n = 248) from August 1996 to July 1997 with an evaluation form and performed abdominal CT subsequent to US whenever the patient was hemodynamically stable and not in need of immediate surgery (n = 105). We documented the results of both methods and their impact on acute therapy. RESULTS: In 27 of 105 patients (25.7%) therapy management was influenced by both either US or CT. 76 patients (72.4%) showed normal US findings, followed by a CT which showed additional findings with therapeutic relevance in five patients (6.6%). Twenty-nine patients (27.6%) showed abnormal US findings. Compared to the therapeutic procedures proposed after the use of US the subsequently performed CT led to a change in therapy in 12 patients (41.4%). CONCLUSION: We conclude that if US is normal, additionally performed CT of the abdomen provides information of therapeutic relevance in only a limited number of cases. If US is abnormal, CT will have an important impact on therapy in a high number of patients.
