Ultrasonographic Diagnosis of Schistosoma mansoni Eggs in Rectum

Abstract EN

Schistosomiasis is a trematode infection endemic in more than 70 countries that affects an estimated 250 million people.

We report the case of a 60-year-old healthy female referred for endoscopic ultrasound after rectal examination revealed granular lesions.

Ultrasound revealed the presence of deep mucosal nodular lesions with calcified/hyperechoic inclusions.

Histologic evaluation has confirmed the final diagnosis of chronic schistosomal colitis.

In patients with nonspecific intestinal lesions without a suspected diagnosis of schistosomiasis, endoscopic ultrasound can be enlightening.

Schistosomiasis is still an endemic infection in some parts of Brazil and other tropical regions, causing colorectal lesions with unspecific presentation.
