Abstract:
A case of intrarenal pseudoaneurysm after blunt trauma in a 12-year-old girl is reported. Clinical evolution was characterised by gross hematuria and colic pain bouts, and several pseudoaneurysms were confirmed through computerised tomography and Doppler ultrasound. In spite of strict bedrest, hematuric episodes occurred on day 11 and day 21 after admission. The pseudoaneurysms were confirmed by Doppler ultrasound and conservative treatment was rejected. 48 hours later, a therapeutic arteriography was performed, but no pseudoaneurysm could be identified, only an arteriovenous fistula that was embolised with coils. To our knowledge this is the first case of documented spontaneous resolution of intrarenal pseudoaneurysm. This case raises the possibility of continuing conservative treatment even in the presence of an intrarenal pseudoaneurysm.
