Which imaging feature is most informative for detecting lymphangiectasia?

• A. Radiographs showing pneumonia
• B. Ultrasound showing hyperechoic mucosal striations
• C. MRI showing brain lesions
• D. CT showing splenomegaly

Answer: (B)

Detecting lymphangiectasia hinges on recognizing changes in the intestinal wall caused by dilated lymphatic channels. Ultrasound is especially informative because it can visualize the mucosa and submucosa, and in lymphangiectasia the mucosa often shows bright, linear patterns known as hyperechoic mucosal striations. These stripe-like lines reflect edema and dilated lacteals within the villi, making this ultrasound finding a strong clue for the condition. Other imaging options don’t specifically target the intestinal lymphatics: radiographs of the chest wouldn’t reveal gut lymphangiectasia, MRI findings in the brain are unrelated, and CT demonstrating splenomegaly isn’t diagnostic for this intestinal process.
