S. Ohta et al., HYPERECHOIC APPEARANCE OF HEPATIC PARENCHYMA ON ULTRASOUND EXAMINATION OF PATIENTS WITH BLUNT HEPATIC-INJURY, The journal of trauma, injury, infection, and critical care, 44(1), 1998, pp. 135-138
Objective: To study the significance of a geographic hyperechoic liver
parenchyma pattern on ultrasound (US) examination of patients with bl
unt abdominal injury. Design: Prospective clinical study with double-b
lind evaluation of images and clinical data. Methods and Main Results:
We performed US examinations in 831 consecutive patients admitted to
our hospital for blunt abdominal trauma and identified 33 with a geogr
aphic hyperechoic pattern in the liver, We correlated the appearance w
ith computed tomographic images and with clinical, angiographic, and s
cintigraphic data, All patients with a geographic hyperechoic pattern
showed mild computed tomographic evidence of hepatic injury (Mirvis gr
ade 2, 69%; Mirvis grade 3, 31%), Excluding patients who required urge
nt surgery for other reasons and patients in shock, patients with the
geographic hyperechoic pattern were managed conservatively with no com
plications, Conclusion: The geographic hyperechoic pattern of liver pa
renchyma on US examination of trauma patients is a mild injury that, o
f itself, does not require surgical therapy.
