Spontaneous rupture of renal tumours: the role of imaging in diagnosis and management.
This study aimed to evaluate whether patients presenting with spontaneous haemorrhage from renal tumours could be accurately diagnosed and initially managed conservatively, and evaluate the role of imaging in guiding the timing and type of subsequent operation. The clinical features, imaging findings and management of seven patients presenting with spontaneous rupture of renal tumour over a 5-year period were reviewed. The information from various imaging studies was evaluated in relation to the subsequent course of intervention. The tumours consisted of six angiomyolipomas and one renal cell carcinoma. In all cases, imaging studies were diagnostic, with computed tomography being the most useful single modality. Emergency surgery was required in one patient for evacuation of suspected infected haematoma and wedge excision of angiomyolipoma. Three elective nephrectomies were performed, while three other patients with ruptured angiomyolipoma were treated conservatively and remained well, without any intervention. In conclusion, patients presenting with spontaneous rupture of renal tumour can be managed conservatively initially. Imaging facilitates accurate pre-operative diagnosis, which was angiomyolipoma in all but one patient in this series. The subsequent intervention can be tailored according to the lesion type and the anticipated risk of re-haemorrhage.
