A case of scrotal venous malformation mimicking a failed varicocelectomy

A 21-year-old man presented to interventional radiology department with several years of left scrotal pain, which exacerbated by prolonged standing and walking. The patient had undergone a left varicocelectomy at the age of 10, after which he had a persistent scrotal mass. As he grew older, the left scrotal mass continued to increase in size, and symptoms progressively worsened. Physical examination revealed a non-tender, firm left scrotal mass which remained unchanged in size after Valsalva manoeuvres. Initial ultrasound examination revealed an extratesticular, intrascrotal mass with minimal internal flow. MRI revealed a heterogeneously enhancing, low-flow venous malformation centred in the midscrotum involving multiple tissue planes. Two sessions of percutaneous sclerotherapy failed to relieve his pain. Three months after the second sclerotherapy, the patient underwent surgical resection. At the time of his postoperative visit, his left scrotal pain had significantly improved and pain with prolonged standing and walking had resolved completely.
