<\/span>What causes megalencephaly-capillary malformation-polymicrogyria?<\/span><\/h2>\nSome cases of MCAP have been found to have somatic mutations<\/span> in phosphatidylinositol-4, the catalytic subunit alpha 5-bisphosphate 3-kinase (PIK3CA<\/em>) gene<\/span> in chromosome<\/span> 3q26.<\/p>\n<\/span>What are the clinical features of megalencephaly-capillary malformation-polymicrogyria?<\/span><\/h2>\nThese main criteria must be present for MCAP to be diagnosed:<\/p>\n
\n- Macrocephaly (> 95th percentile) and progressive<\/span> megalencephaly<\/li>\n

<\/span>How is the diagnosis of megalencephaly-capillary malformation-polymicrogyria made?<\/span><\/h2>\nThe diagnosis of MCAP is made on the basis of clinical signs and neuroimaging studies. Both main criteria must be present, with variable minor criteria.<\/p>\n
Base<\/span> magnetic resonance image<\/span> (Magnetic resonance<\/span>) of the brain and spine is recommended at the time of diagnosis.<\/p>\n\n

<\/span>Which is the differential diagnosis<\/span> for megalencephaly-capillary malformation-polymicrogyria?<\/span><\/h2>\nMCAP must be distinguished from other vascular malformation overgrowth syndromes including:<\/p>\n
\n- Skin<\/span> marmorata telangiectatica congenita<\/li>\n
- Beckwith Weidemann syndrome<\/li>\n

<\/span>What is the result of megalencephaly-capillary malformation-polymicrogyria?<\/span><\/h2>\nMCAP patients require ongoing medical surveillance, as well as physical and occupational therapy. Early intervention is helpful in overcoming disability and achieving developmental milestones.<\/p>\n
Patients are at increased risk of developing medulloblastoma, meningioma, Wilms tumor, and leukemia<\/span> throughout his life. <\/p>\nIn addition to annual medical exams, all patients must have a cardiology consultation at the time of diagnosis.<\/p>\n
Follow-up image recommendations include:<\/p>\n
\n- MRI of the brain at diagnosis and every 6 months until age 2 years.<\/li>\n
