Intestinal Ascariasis: The Unsuspected Cause of Acute Abdomen Detected on Ultrasonography

We present here a case of 15 years old male child who presented with acute pain abdomen in the emergency to a community level hospital in a suburban area. Patient was taken for abdominal ultrasonography and on evaluating the gut with linear ultrasound probe (3-12 MHz) multiple tubular structures, with four long parallel well defined echogenic lines were seen in longitudinal view with central hypoechoic area [Figure 1, arrows]. These appear oval to round in cross section with central hypoechoic area [Figure 2, arrows] within the small intestinal lumen.
