[Renal infarction in the evaluation of lumbar pain]

We report the case of a young patient without known cardiovascular risk factors, complaining of lumbar colic pain due to renal infarction.

Differential diagnosis of lumbar colic pain must include some rare events. We performed a review of the current knowledge on the topic.

The increasing difficulty in the diagnosis of these pathology lies on its clinical suspect, which can be clear when having cardiovascular risk factors. Its diagnosis, on a rare scenario, needs leucocytosis and LDH rising as suspicious indicators. Computed tomography, MRI, radionuclids and arteriography may confirm diagnosis. Treatment is based on thrombolytic therapy, anticoagulants and ontiagregants.
