Hypomagnesaemia Induced Reversible Cerebellar Syndrome.

Hypomagnesaemia may cause neurological symptoms as part of its presentation. This case demonstrates one such unusual example of a reversible cerebellar syndrome resulting from magnesium deficiency. An 81-year-old woman presented to the emergency department with a history of chronic tremor and other cerebellar signs. Severe hypomagnesaemia was detected within her initial biochemistry results. Correction of this deficiency led to a resolution in her symptoms.
