Urachal Remnant Infection Caused by Actinomyces Turicensis

Urachal remnants (URs) represent uncommon and underdiagnosed entities that are usually detected incidentally at imaging or present clinically different manifestations.

Here we presented a boy with UR infection. Ultrasonography and bacterial culture and identification were performed. He received antibiotic treatment and underwent surgical excision of the cyst.

The patient presented with both a urachal cyst and umbilical-urachal sinus. UR infection was caused by Actinomyces turicensis. He recovered well from the operation without complications.

The present case reminds clinicians to be familiar with imaging features of different types of URs and their potential complications and indicates the necessity of pathogenic microorganism analysis to tailor antibiotic treatment and post-operative follow-up to prevent complications.
