[Diagnosis of discitis using MRI in children]. / Diagnóstico de la discitis mediante resonancia magnética en el niño.

Two patients developed unsteady gait and presented pathological neurologic signs in lower extremities which lead to suspect an expansive process in the spinal cord. The radiological exploration was normal in both cases. Magnetic resonance imaging resulted in diagnosis of discitis. A revision has been carried out of the different diagnostic procedures and the possible indications for magnetic resonance imaging.
