Post-traumatic intrasplenic pseudoaneurysms with delayed rupture: color Doppler sonographic and CT findings.
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.
