If the syringomyelia becomes hard lump, it is recommended to go to hospital for further examination to clarify the cause: 1. If the fluid is gradually absorbed, the hard lump felt is an inflammatory change in the scrotum, such as an inflammatory nodule in the testicle or an inflammatory nodule in the epididymis, which can be identified by further ultrasound examination of the scrotum; 2. This kind of encapsulated syringomyelia is accompanied by elevated surface tension, so it forms a hard mass when touched, which can be further clarified by ultrasound examination of the scrotum; 3. This is usually accompanied by increased swelling of the scrotum.
