[Partial thrombosis of the corpus cavernosum. Must a clotting disorder be systematically investigated?].

The authors report a case of partial thrombosis of a corpus cavernosum, confirmed by MRI imaging. In this patient, a neuroleptic had been prescribed several days before the thrombosis and the clotting assessment demonstrated protein C resistance. Conservative management comprising low molecular weight heparin and aspirin was instituted. Three months later, pain had resolved and signs of a thrombotic scar persisted on MRI. The aetiology of thrombosis of the corpus cavernosum, a rare disease, remains unknown. Neuroleptic therapy has been incriminated. In the light of this case, the authors emphasize the value of systematic clotting assessment.
