Modifier le texte d'un rapport médical

Edit the medical ultrasound report document. Find the line 'The hepatic parenchymal echogenicity is mildly increased with more fine echoes dispersed throughout the hepatic parenchyma, suggestive of diffuse fatty infiltration.' and replace it with 'Homogeneous parenchyma with normal echogenicity. No diffuse or focal hepatic mass/lesion is identified.' The replacement text should not be bold. Keep the rest of the document exactly the same — same fonts, layout, spacing, and overall style.
