Neurocardiogenic pulmonary oedema: initial presentation of multiple sclerosis.

A previously healthy 20 year-old male presented with headache, acute pulmonary oedema and left ventricular dysfunction requiring intensive care admission. Cardiorespiratory symptoms resolved within three days; however, the patient complained of persistent headache and had gait unsteadiness. Magnetic resonance imaging showed a large demyelinating lesion in the caudal medulla with scattered cerebral plaques. The patient was subsequently diagnosed with multiple sclerosis. This case describes a rare initial presentation of multiple sclerosis with acute pulmonary oedema and cardiac dysfunction secondary to a lower brainstem lesion.
