[Parenchymal splenic lesion after a water balloon shot].

Acute splenic rupture can be a life-threatening condition which needs immediate attention. We report a case where parenchymal splenic lesions and subcapsular haematoma were developed after a patient was being hit with a water balloon from a slingshot. The patient was treated conservatively but developed an arteriovenous fistula which was treated with central arterial coiling. We discuss the need for acute computed tomography after relevant trauma as well as the evidence for follow-up scans and management of splenic pseudoaneurysms with splenic arterial embolization.
