High-flow priapism associated with Fabry's disease in a child: A case report and review of the literature

We report a case of priapism in an 11-year-old boy known to have Fabry's disease. High flow was confirmed by color flow Doppler ultrasound and intracorporal blood gas measurements. Successful treatment was achieved by unilateral percutaneous Gelfoam embolization of the left internal pudendal artery. Previously reported cases of priapism associated with Fabry's disease were identified through a MEDLINE search of the English literature and review of the publications. Five reported cases of priapism associated with Fabry's disease were found, including those of 3 children. A report of a child with high-flow priapism that did not respond to conventional treatment including cavernovenous shunting was noted. Priapism associated with Fabry's disease may be caused by unregulated high arterial inflow. Early recognition of the underlying pathophysiology may identify those cases that would be amenable to percutaneous embolization therapy and may obviate the need to pursue other ineffective conventional treatments.
