PURPOSE: To describe the vascular and nonvascular intracranial and extracranial anomalies associated with hemangiomas and vascular malformations of the face, neck, and/or chest.
METHODS: Seventeen patients had a physical examination and imaging studies consisting of one or more of the following: pneumoencephalography, conventional carotid and vertebral arteriography, CT, MR imaging, and MR angiography.
RESULTS: Conventional arteriography revealed persistence of the trigeminal artery in 5 cases, absence of internal or external carotid and/or vertebral arteries in 11 cases, persistence of intervertebral arteries in 1 case, deformities of the aortic arch in 3 cases, and anomalies of the intracranial arteries in 3 cases. MR angiography revealed persistence of the trigeminal artery in 1 case in which conventional arteriography failed to show the malformation, and permitted visualization of narrowing of the intracranial arteries. CT and MR imaging showed a cerebellar anomaly in 8 cases and cerebral cortical dysplasia with cerebral hemispheric hypoplasia in 1 case. Vascular and nonvascular anomalies appeared ipsilateral to the external vascular abnormalities in most cases.
CONCLUSION: This study demonstrates the association of cutaneous angiomas with anomalies affecting intracranial and extracranial arteries, the cerebellum, and, less frequently, the cerebral hemispheres and aortic arch. This association constitutes a relatively frequent neurocutaneous disorder, which we call the cutaneous hemangioma-vascular complex syndrome.
