Introduction:
High-flow priapism is infrequent in pediatric patients. It is mostly secondary to perineal trauma resulting in laceration of a penile artery and the formation of an arterio-cavernous fistula. It does not constitute a medical emergency in itself, and allows conservative management awaiting spontaneous resolution.
Clinical Case:
A six-year-old boy with painless persistent erection preceded by perineal trauma. Ultrasound imaging confirmed the clinical suspicion of high flow priapism secondary to arterio-cavernous fistula. After adopting a conservative approach, the patient presented progressive detumescence, as well as ultrasound resolution one month after the episode.
Comments:
In high-flow priapism, venous drainage of the penis is preserved. The classical approach in adults is based on therapeutic angiography, which presents greater technical complexity and the risk of iatrogenic hypoxia in pediatric patients.
