Objectives: Priapism is a persistent erection of the penis not associated with sexual stimulation. High-flow priapism is caused by unregulated arterial inflow, usually preceded by perineal or penile blunt trauma and formation of an arterial-lacunar fistula. We present a case of high-flow priapism in a 13-year-old patient managed with polyvinyl alcohol particles. Methods: After obtaining informed consent of the parents of the minor, diagnosis was made with penile Color Doppler Ultrasound and confirmed with flush angiography. Selective arterial embolization was performed with the use of polyvinyl alcohol particles. Results: Complete detumescence was achieved without compromising the patient’s erectile function. Conclusions: The use of permanent occlusive agents like polyvinyl alcohol particles for embolization shows good occlusion rates compared to temporary agents. More studies are needed to find the safer and better agent for the treatment of high flow priapism without compromising erectile function.

Neurofibromatosis type 1 (NF1) is an autosomal dominant multisystem genodermatosis resulting from a mutation on chromosome 17q11.2, characterized by diverse clinical expression with involvement of the skin, nervous system, bones, eyes and other systems. Neurofibromas are tumors located along nerve bundles; when they become large, they are called plexiform neurofibromas. Complications of neurofibromas are rare, but include malignant transformation and potentially life-threatening hemorrhages. A comprehensive perioperative management, including arterial embolization of feeding vessels, is required in order to perform a safe surgical procedure and to reduce potential surgical complications. We report a case of a large plexiform neurofibroma on the right flank, treated in a two-stage approach: first, embolization with polyvinyl alcohol particles of the inferior epigastric, lumbar and superior gluteal arteries on the right and, second, 24 hours after embolization, exeresis of the lesion, which weighed 2.5 kg. Two years after surgery, the patient was asymptomatic, without tumor recurrence and with an important improvement in self-esteem and quality of life.
