Whipworm infection other imaging findings

A double contrast barium enema will demonstrate the presence of multiple tiny target-like or pinwheel shaped collections of barium, associated with s-shaped filling defects and appearance characteristic of a male worm with a coiled tip.

• The characteristic appearance of male T. trichiura on double contrast barium enema is the presence of multiple tiny target-like or pinwheel shaped collections of barium associated with s-shaped filling defects.
• The male adult has an s-like shape. Barium gets trapped in the complete loop of the “s,” appearing as a pinwheel shaped collection. This corresponds to the posterior coiled portion of the worm.
