Capillary Malformation Diagnosis

Diagnosis is usually based on clinical observation. Various sets of criteria have been suggested to identify the disorder in an individual patient, all of which include macrocephaly and a number of the following: somatic overgrowth, cutis marmorata, midline facial birthmark, polydactyly/syndactyly, asymmetry (hemihyperplasia or hemihypertrophy), hypotonia at birth, developmental delay, connective tissue defect and frontal bossing. Currently no consensus exists about which diagnostic criteria are definitive and so evaluation by a medical geneticist or other clinician with familiarity with the syndrome is usually needed to provide diagnostic certainty. It is not clear if there are some features which are mandatory to make the diagnosis, but macrocephaly appears essentially universal though may not be congenital. The distinctive vascular abnormalities of the skin often fade over time, making the diagnosis challenging in older children with this condition.

The brain can be affected in several ways in this syndrome. Some children are born with structural brain anomalies such as cortical dysplasia or polymicrogyria. While developmental delay is nearly universal in this syndrome it is variable in severity, with the majority having mild to moderate delays and a minority having severe cognitive impairment. Some patients are affected with a seizure disorder. White matter abnormalities on magnetic resonance imaging (MRI), suggesting a delay in white matter myelination, is commonly seen in early childhood. Some patients may have asymmetry of the brain, with one side being noticeably larger than the other.

One interesting phenomenon that seems very common in this syndrome is the tendency for disproportionate brain growth in the first few years of life, with crossing of percentiles on the head circumference growth charts. A consequence of this disproportionate brain growth appears to be a significantly increased risk of cerebellar tonsillar herniation (descent of the cerebellar tonsils through the foramen magnum of the skull, resembling a Chiari I malformation neuroradiologically) and ventriculomegaly/hydrocephalus. Such cerebellar tonsil herniation may occur in up to 70% of children with M-CM.

The medical literature suggests that there is a risk of cardiac arrhythmias in early childhood. The cause for this is unknown. In addition, a variety of different congenital cardiac malformations have been reported in a small number of patients with this disorder.
