[Subcapsular kidney hematoma: a rare complication of paravertebral infiltration]

Two patients developed subcapsular hematomas of the kidney following orthopaedic paravertebral injection. Clinical course and radiological findings are reported. Renal subcapsular hematomas are indeed frequent complications after stomach and lower thorax injuries; these are also known after diagnostic or therapeutic kidney-punctures. However, damage to the kidney by paravertebral injection is extremely unusual and not previously reported in the literature.
