“…More commonly, patients will present with symptoms related to the facial AVMs, including progressive vision loss resulting in blindness (22,23), bleeding from the teeth and gums, and cosmetic problems (eg, facial asymmetry) (19,23,24). Recurrent bleeding from maxillary and mandibular AVMs is often severe, and endovascular treatment is the best option in Figure 6.…”

Brain arteriovenous malformations (AVMs) are abnormal vascular connections within the brain that are presumably congenital in nature. There are several subgroups, the most common being glomerular type brain AVMs, with fistulous type AVMs being less common. A brain AVM may also be a part of more extensive disease (eg, cerebrofacial arteriovenous metameric syndrome). When intracranial pathologic vessels are encountered at cross-sectional imaging, other diagnoses must also be considered, including large developmental venous anomalies, malignant dural arteriovenous fistulas, and moyamoya disease, since these entities are known to have different natural histories and require different treatment options. Several imaging findings in brain AVMs have an impact on decision making with respect to clinical management; the most important are those known to be associated with risk of future hemorrhage, including evidence of previous hemorrhage, intranidal aneurysms, venous stenosis, deep venous drainage, and deep location of the nidus. Other imaging findings that should be included in the radiology report are secondary effects caused by brain AVMs that may lead to nonhemorrhagic neurologic deficits, such as venous congestion, gliosis, hydrocephalus, or arterial steal.

“…Gait ataxia and CSF rhinorrhea are uncommon presentations that indicate neurological complications associated with CAMS. 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 Imaging techniques include a protocol consisting of CT brain, CT angiography, and MRI brain. Arteriovenous malformations were identified in different anatomical regions, including the Willis polygon, orbit, suprasellar region, brainstem, cerebellum, thalamus, hypothalamus, and optic nerve.…”

Key Clinical MessageCerebrofacial arteriovenous Metameric syndrome (CAMS) typically manifests as types I, II, or III, occasionally presenting as dual types. Our unique case underscores the coexistence of all three CAMS types in one patient. Furthermore, the concurrent acute cerebellar infarct underscores the need to consider CAMS in the differential diagnosis of adolescents experiencing neurological events.

“…Hox genes play an important role in signaling the appropriate embryonic segmentation for brain and craniofacial development. 30,50 Specific Hox genes have also been shown to play important roles in endothelial and capillary development, potentially implying their involvement in CMS. 50 Other genes with well-established functions, including GNAQ (associated with Sturge-Weber) and PIK3CA , may also play an underlying role in CVMS pathogenesis.…”

[49][50][51] Patients presenting with mixed CAMS phenotypes are more common than patients with isolated CAMS subtypes. Clinical and imaging findings of such patients may consist of multiple of those seen in the individual CAMS phenotypes.…”

The cerebrofacial metameric syndromes: An embryological review and proposal of a novel classification scheme

et al. 2021

View full text Add to dashboard Cite

The cerebrofacial metameric syndromes are a group of congenital syndromes that result in vascular malformations throughout specific anatomical distributions of the brain, cranium and face. Multiple reports of patients with high-flow or low-flow vascular malformations following a metameric distribution have supported this idea. There has been much advancement in understanding of segmental organization and cell migration since the concept of metameric vascular syndromes was first proposed. We aim to give an updated review of these embryological considerations and then propose a more detailed classification system for these syndromes, predominately incorporating the contribution of neural crest cells and somitomeres to the pharyngeal arches.
