Ultrasound Evaluation of Perianal Diseases in Infants.

Organs and tissues comprising the perianal area include the caudal segments of the digestive system and reproductive system, the perianal soft tissues, and the terminal part of the spinal cord. Diseases originating in one part of the perianal region may have connections with others. Incomprehensive and disorganized ultrasound (US) scanning may lead to insufficient diagnostic information, potentially impacting the effectiveness of subsequent treatment. The purposes of this paper are (a) to describe our technique of performing US of perianal area; and (b) to explore the diagnostic strategy of US in infant perianal diseases by outlining the sonographic characteristics of these conditions.
