Ultrasonographic findings of Diphyllobothrium nihonkaiense: A case report

Abstract

A 6-year-old girl was admitted to our hospital due to discharging the strobila of a tapeworm (Diphyllobothrium nihonkaiense) from her anus. Before excreting the tapeworm completely with anthelmintics, ultrasonography was performed. The tapeworm was shown as a slightly high echoic strand-like lesion on ultrasonography in the terminal ileum. In this strand-like lesion, some high echoic spots were detected. This finding was considered as a characteristic of Diphylloborthriasis.

Tapeworm (Diphyllobothrium nihonkaiense) detected by abdominal ultrasonography

“…The effectiveness of ultrasound has been reported in several publications. 3 , 4 In cases such ours, ultrasound is useful for deciding whether to treat patients with praziquantel because the tapeworms are extracted naturally. In conclusion, abdominal ultrasonography can be useful for diagnosing diphyllobothriasis.…”
