A 2-year-old boy had glaucoma, bilateral facial haemangioma and widespread blue nevi on the trunk and extremities since birth. Dilated medullary veins were detected in the left cerebral periventricular white matter on magnetic resonance imaging (MRI). Macrocephaly and delayed psychomotor development were observed during late infancy, and susceptibility-weighted angiography revealed an extensive developmental venous anomaly with multiple caput medusae throughout bilateral hemispheres, accompanied by periventricular hyperintense alterations on MRI and progressive diffuse atrophy of the cerebral mantle with left-sided predominance. Hypoperfusion in the left cerebral and cerebellar hemisphere was also uncovered. No meningeal haemangioma was observed. This patient may represent a novel subgroup of phakomatosis cases that can be regarded as a variant of Sturge-Weber syndrome.
