VARGAS DIAZ, José et al. Clinical-epidemiological and evolutive diagnosis of leukodystrophy, megalencephaly and subtemporal cysts during breastfeeding. Rev Cubana Pediatr [online]. 2020, vol.92, n.3, e1099.  Epub Sep 01, 2020. ISSN 0034-7531.


Primary leukodistrophies are a group of hereditary disorders that affect in a predominant way the white substance of the brain. The term ´´primary leukodistrophies´´ unifies the diseases that affect the glial cells compromising myelin and the genetic based axon. They are a group of entities, more tan 30 nowadays, which are expanding due to the advances in magnetic resonance and genetics.


To contribute to the understanding of this rare disease with emphasis in the usefulness of its clinical knowledge and in the evolutive studies of images for diagnosis.

Case presentation:

Female patient with macrocranea detected by the family at 3 months old. At the beginning, the family referred that the cephalic circumference grew quickly and from the second semester of life growing process was slower. The clinical assessment at first year of life proved a discreet difficulty for cephalic control; the patient tried to do support footsteps, and had a language of 3 to 4 words without any other affectation in the neurodevelopment. In the physical examination, she presented a cephalic circumference of 55 cm (higher than the two stantard deviations for the cronological age and sex).


The clinical evolution was favorable jointly with the pattern of brain magnetic resonance that initially showed affectation in the white substance compatible with inespecific leukodistrophy and in the evolutive studies it was detected the presence of subtemporal cysts which allowed to diagnose this rare children disease. The patient received symptomatic treatment for spasticity, pedagogical support and control of the epileptic crisis.

Keywords : leukodistrophy; macrocranea; leukoencephalopathies; megaloencephalic leukoencephalopathy with cysts (MLC).
