Multidetector computed tomography findings of spontaneous renal allograft ruptures.
OBJECTIVE
To describe the characteristics of spontaneous renal allograft rupture using multidetector computed tomography (MDCT).


METHODS
Five patients with spontaneous renal allograft rupture, as confirmed by pathologic examination, were referred to our institution between 1985 and 2008. The clinical records and preoperative MDCT findings of the patients were studied retrospectively.


RESULTS
Clinical and/or histological findings were consistent with acute rejection in all cases. Using MDCT, disruption of the capsular integrity and parenchymal rupture was seen in four patients. Four of the five patients showed decreased enhancement and swollen grafts. Perirenal (n=4), subcapsular (n=1), and intraparenchymal (n=1) haematomas were also seen. In the patient with an intraparenchymal haematoma there was no disruption of capsular integrity, but capsular irregularities were seen near the haematoma.


CONCLUSIONS
MDCT is a useful investigative tool for the evaluation of suspected spontaneous renal allograft rupture. As well as a swollen graft, disruption of the capsule, parenchyma, and/or haematoma should prompt the radiologist to consider this diagnosis.
