Summary
Primary hypomagnesaemia can cause rapid head enlargement and brain shrinkage in children. This condition is reversible with timely magnesium treatment, offering new hope for affected families.
Area of Science:
- Pediatric Neurology
- Renal Physiology
- Medical Genetics
Background:
- Primary hypomagnesaemia is a rare genetic disorder characterized by renal magnesium wasting.
- This condition can lead to severe neurological complications if left untreated.
Observation:
- Two siblings presented with rapidly increasing head size, a previously unreported symptom.
- Computed tomography (CT) scans revealed external hydrocephalus and brain shrinkage.
Findings:
- The observed neurological changes were directly linked to primary hypomagnesaemia.
- Reversibility of external hydrocephalus and brain shrinkage was achieved through magnesium supplementation.
Implications:
- This study highlights a novel clinical manifestation of primary hypomagnesaemia.
- Early diagnosis and magnesium treatment are crucial for preventing irreversible neurological damage.
