Ultrasonic display of blood on both sides of the splenogastric ligament (left butterfly sign) in the left traumatized patient indicates hemoperitoneum within the lesser sac. Particular attention must be paid then to the splenic parenchyma, where isoechogenic blood clots can mask a hematoma. The association of subtile parenchymal changes and of a left butterfly sign are relevant of frank splenic lesions.
脾脏外伤患者左侧脾胃韧带两侧血液的超声显示（左侧蝴蝶征）提示小网膜囊内存在腹腔积血。此时必须特别注意脾实质，等回声血凝块可能掩盖脾实质内的血肿。脾实质细微改变与左侧蝴蝶征同时出现提示存在明显的脾脏损伤。
