“…Extradural angiomas, accounting for 15 to 20% of all spinal vascular anomalies [17,190] and for about 4,7% of all spinal space-occupying lesions [199], include all types of malformation and are rarely isolated [192,244]. Their feeding vessels usually exhibit no communication with the spinal cord arteries and thus, these malformations play no part in the vascular supply of the cord.…”

“…However, for the majority of intradural vascular anomalies previously classified as spinal varices [88,100,149,183], spinal varicosis [17,138,236,259], or racemose venous angiomas [46,47,132,204,218,219], spinal angiography, by demonstrating arterial feeders, offered the definite proof that they are actually AVMs [11, 53-55, 58, 59, 62]. Slowing of circulation, darker-colored vessels, and partial thrombosis giving the impression of a venous origin may cause difficulties in the in vivo separation of arteries and veins during surgery.…”

“…Thoracolumbar, lumbar and lumbosacral angiomas account for 40-60% of all spinal vascular anomalies and up to 80% of the intradural angiomas, the majority being located below T 6 to T 10 [17,59,121,138,140,190,192,193,248,249,259,260]. They include intradural and subarachnoid AVMs and capillary angiomas, the latter being usually smaller and circumscribed [192].…”

“…These radicular changes apparently occur before damage to the cord and thus may explain the initial clinical signs and symptoms. About half of the patients have an acute onset of pain and dysesthesia [2,17,140] or complain of intermittent sciatica [124,191,257] and "dysbasia intermittens spinalis" [75] with transient weakness and sensory disturbances [257], followed by progressive radiculospinal symptoms. In a number of patients having had surgically treated sciatica, similar lumbosacral epidural vascular anomalies have been demonstrated [95].…”

Vascular malformations of the central nervous system (C.N.S.) are classified by size, location, and morphologic type, distinguishing capillary telangiectasias, cavernous malformations, venous angiomas, arteriovenous malformations (AVMs) including varix of the great vein of Galen, and other vascular malformations (e.g. Sturge-Weber syndrome). The morphology and predominant location pattern of the different types of vascular malformations in the brain and spinal cord, and their embryology are reviewed. In the brain and its coverings, all types mainly AVMs and venous angiomas do occur, representing 5-9% of all intracranial space-occupying lesions and 20-40% of the sources of surgically treated intracranial hemorrhages. 50-80% of the angiomas are located in the cerebral hemispheres, 10-18% in central brain areas (basal ganglia, internal capsule, choroid plexus), and 10-30% in the posterior fossa. The major types of cerebral vascular malformations are described with reference to their anatomical features, location, chief arterial and venous supply, and prominent complications. Spinal vascular malformations, accounting for 3 to 12% of spinal space-occupying lesions, include vertebral, extradural, dural, subpial and intramedullary angiomas which occur as isolated or complex vascular anomalies and may involve various covering layers at the same level. The preferential occurrence of angiomas on the dorsal surface of the cord and in the caudal regions is related to the embryologic development of spinal vasculature. Frequent association of spinal angiomas (20-25%) with other vascular anomalies and dysplasias emphasizes their hamartomatous nature and developmental origin. Spinal angiomas include capillary telangiectasias with extra- or intradural and, rarely, intramedullary location, cavernomas, mainly arising in vertebral bodies, venous angiomas, mainly located in vertebral bodies and in the extradural space, and AVMs constituting the commonest type, that may affect both the pial and radicular vessels and can penetrate into the cord. They present as simple AV fistulas, cirsoid angiomas with localized vascular plexuses and large complex convolutions ("juvenile" type). The complications of spinal angiomas include subarachnoid hemorrhage, rare epidural hematoma, hematomyelia, compression lesions of the cord and roots, and ischemic changes causing chronic progressive radiculomyelopathy, previously referred to as Foix-Alajouanine syndrome. Chronic damage to the cord and spinal roots results from pressure effects, thrombosis of the abnormal vessels, disorders of venous drainage, and "steal" phenomena related to the vascular anomalies.

This case was presented as an interesting example of a global arteriovenous malformation (AVM) involving muscle, bone, extradural and intradural spaces of the cervical region.A twenty-eight year old male in October, 1976, fell at work sustaining a blow to his lower back. The following day he complained of cervical pain. Physical examination was negative and he had a full range of movement of his cervical spine.Plain films and tomograms of the cervical spine showed a lytic honeycomblesion of C2 and C3, and a 4 mm. subluxation of C3 on C4 (Fig. 1). The bone scan showed increased flow and decreased static activity in the upper cervical region. The radiological diagnosis was vertebral hemangioma; tumor, infection and histiocytosis were unlikely but important differential considerations.
