Endoscopic Discovery of a Taenia in the Duodenal Bulb

Table of Contents

Figure 1 A 70-year-old woman underwent esophagogastroduodenoscopy for iron-deficiency anemia. A flat white noodle-like formation was seen coiled up, making several loops, in the duodenal bulb. During the procedure, it moved down and disappeared into the jejunum. This is the second reported case of endoscopic discovery of Taenia in the bulb. The usual site of the adult Taenia is the small bowel. In this case, the scolex was probably attached in the upper jejunum and the anterior portion of the body had moved up into the bulb. This is confirmed by the fact that the proglottids seen in the image, appear wider than long; this is found in the anterior and middle region of most Taenia species.
