Small lumps palpated in the scrotum are most commonly testicular epididymal cysts as well as epididymal inflammatory nodules, while lumps of other nature are generally less common. If there is obvious pain during touching, epididymal inflammatory nodules are more likely, otherwise simple cystic lumps are more likely. Through ultrasound examination, the size of the mass and its location can basically be clarified. Treatment should be combined with the specific situation, if inflammation is the main manifestation, choose anti-inflammatory treatment, if the cystic mass, the size of the mass is not large, can be regularly reviewed, if there is a tendency to increase in the future review process, can be surgical resection.
