Pediatric priapism associated with Mycoplasma pneumoniae.

Author information

Department of Surgery, Abington Memorial Hospital, Pennsylvania 19001, USA.



Priapism in the pediatric population is rare and most commonly occurs secondary to sickle cell disease or hematologic malignancy. We present a case of a 12-year-old boy with priapism who required aggressive surgical therapy for adequate detumescence. This patient had a recent viral upper respiratory infection and titers for Mycoplasma pneumoniae were indicative of infection. We propose that a hypercoagulable state was induced by the M. pneumoniae infection, which resulted in the priapism.


A 12-year-old boy with a recent upper respiratory illness presented to his pediatrician with priapism. After failing conservative management, the patient ultimately required a surgical shunt for detumescence. Serum was sent to detect antibodies against M. pneumoniae.


The child failed to respond to corporeal irrigations and bilateral Winter shunts. He underwent an El-Ghorab procedure the following morning, which resulted in a flaccid penis. Serum M. pneumoniae antibodies were detected and indicated moderate infection.


We propose that this 12-year-old boy had priapism secondary to infection with M. pneumoniae. M. pneumoniae infection can produce a hypercoagulable state, especially in selected areas of the circulation. This is the first reported case of priapism associated with M. pneumoniae.
