Paraurethral cysts of non-traumatic origin are very rare with only a few cases described in the literature (Hakenberg et al. 2000 Bujons et al. 2006). They are usually secondary to submucosal gland distension and appear at ultrasound as lesions with typical anechoic appearance (Fig. 19.10) that adject in the distended urethral lumen. Sonourethrography is indicated to locate the lesion and to assess the relationships with the urethra.

These lesions have been described in Chapter 19. In brief, paraurethral cysts are usually secondary to submucosal gland distension and appear at ultrasound with a typical anechoic appearance. Syringocele presents at sonourethrography as a tubular image at the bulbous urethra, parallel to the urethral canal, with a double tube appearance. 

Ectopic ureterocele develops at the lower end of the upper pole ureter of a duplicated kidney. It is a cyst-like thin-walled structure that is known to be mobile and variable in shape. During fetal life, the ureterocele can prolapse into the posterior urethra and create obstruction (Fig. 6.9). Bilateral hydronephrosis and megacystis can subsequently develop. Clinical diagnosis can be made at birth in girls with a perineal soft tissue mass, megacystis and bilateral urinary tract obstruction. Sonographic diagnosis can be difficult when the ectopic ureterocele has...
