[Subcapsular spontaneous hematoma of the kidney of non-tumor origin (report of 5 cases)].

Spontaneous subcapsular haematoma (SCH) of the kidney is a rare condition, secondary to kidney tumours in more than 50% of cases. Nephrectomy is justified in the presence of tumour or uncontrolled haemorrhage. When the aetiology cannot be determined, thin-slice CT follow-up of the patient's kidney can be performed. The authors report 5 cases of SCH of the kidney. A retropelvic aneurysm was responsible for the haematoma in one case; polyarteritis nodosa was the cause of bleeding in another case and the aetiology could not be determined in two cases. All patients were managed surgically. Nephrectomy was performed in 3 cases and simple evacuation of the haematoma was performed in 2 cases.
