Ultrasonography of the abdomen revealed dilated large bowel loops and an elongated, linear, hypoechoic tubular structure with well-defined echogenic walls in the transverse colon, which was actively moving (Figure 1).

Contrast-enhanced computed tomography (CT) scan re-vealed a long, linear, hyperdense, non-enhancing structure (~80-90 cm in length) in the lumen of the transverse colon with the features of bowel obstruction (Figure 2).

The patient was managed conservatively for the bowel obstruction with administration of 100 mg albendazole twice daily for 3 days. The obstruction relieved over a period of 5 days, and patient reported the passage of a large dead worm with his stools after 5 days of treatment (Figure 3).
