Hymenolepiasis is an infection caused by Hymenolepis nana (H. nana) and H. diminuta (H. diminuta). Hymenolepiasis is prevalent throughout the world with human infections with H. nana being frequently reported in the literature as compared to H. diminuta. Hymenolepiasis is more frequent among children, and most human infections remain asymptomatic and self-limited. Symptoms including abdominal pain, diarrhea, and vomiting are frequently noted in the cases of heavy infections. We report a case of hymenolepiasis caused by H. nana in a pregnant woman.
