Abstract
Magnesium is the second most abundant intracellular cation and is a fundamental cofactor in a multitude of cellular enzymatic reactions. Magnesium deficiency causes diverse clinical features predominantly due to cardio- and neurotoxicity. We describe a case of severe hypomagnesaemia associated with intermittent downbeat nystagmus, cerebellar ataxia, generalised convulsions and a supraventricular tachycardia. On MRI imaging, a transient lesion of the cerebellar nodulus was observed, which has not, to our knowledge, been previously described in isolated hypomagnesaemia.
