“The baby’s scrotum was not the same size on both sides and was slightly better after a night’s rest. The activity is big again.” Often parents and friends come to ask the doctor for such things. In fact, this phenomenon generally supports that your baby has congenital scrotal syringomyelia. Scrotal syringomyelia is mainly a developmental process of the child’s testicles fall, along with the testicular descent of the peritoneum wrapped around the outside of the testicles to form a testicular syringomyelia did not completely close its passage with the abdominal cavity, so that the abdominal cavity and the testicular syringomyelia between the existence of a very thin traffic pipe, the daytime baby to stand up and move the abdominal cavity of the liquid will be along the pipeline down into the testicular syringomyelia, the formation of the scrotum is enlarged. General physical examination when it is easy to check out, find experienced doctors touch, or use a flashlight to shine photography can be seen through the light commonly known as translucent test positive, can also be ultrasound will be found to be liquid. If the baby is lying down for a period of time the fluid will flow back into the abdominal cavity, so there will be a night’s rest, the next day when you get up there will no longer be fluid, a little activity will be the phenomenon of fluid accumulation, fluid accumulation of the side of the testicles slightly leaning in on the side of the testicle is also possible. Since the right testicle descends later than the left, and the sheath bulge closes later than the left, it occurs more often on the right side than on the left. Usually, the syringomyelia has the potential to grow back on its own in babies up to one year of age, and after one year of age this self-closure is rarely possible. At this point we need to consider surgical treatment.
