If simple spermatic sheath effusion appears at birth, it may subside by itself within two years of age; if secondary spermatic sheath effusion appears in adults, it is very unlikely to heal by itself. 1. Seminal cord syringomyelia is a condition in which the two ends of the syringomyelia are closed during development and the intervening area is not closed, and the main manifestation is a unilateral lump in the groin or above the testis. If the disease is slow, with little fluid and little tension, and there are no obvious symptoms, seminal cord syringomyelia may be absorbed by itself within two years of age, and it does not need any special treatment. 2. If the syringomyelia is obvious and the tension is large, it may affect the testicular development, then it is necessary to consider puncture and fluid extraction treatment. If the patient is already an adult, he or she also needs to actively receive targeted treatment from the doctor, because the spermatic cord syringomyelia in adult patients basically will not be self-healing, and if the treatment is not timely, it may lead to more serious diseases. It is recommended that patients with syringomyelia go to regular hospitals for timely treatment and strive for early recovery.
