“…This is a unique case of cutaneous and retinal vascular malformations in association with hydranencephaly. MRI and MRA findings in our patient are consistent with findings in other patients with hydranencephaly [Torre and Occhipinti, 1969]. Malformations of the carotid arteries have been observed in other hydranencephalic infants.…”

“…Sendelbach et al [1992] reported a case of multicystic encephalomalacia in association with a congenital weblike malformation of the right common carotid and left subclavian arteries. Another case had a virtually absent internal carotid artery system [Torre and Occhipinti, 1969]. Two cases had unilateral stenosis of the internal carotid artery associated with hydranencephaly [McLendon et al, 1986].…”

“…We report an infant with hydranencephaly and congenital vascular malformations including cutaneous vascular malformations. Cases of hydranencephaly with arterial and venous malformations have been reported [Thelander et al, 1953; Torre and Occhipinti, 1969; Nau et al, 1979; McLendon et al, 1986], but to our knowledge there are no previous reports of the association of hydranencephaly with cutaneous vascular malformations.…”

Hydranencephaly in an infant with vascular malformations

Hydranencephaly is a condition in which cerebral hemispheres are absent and reduced to fluid-filled sacs in a normal skull. Numerous causes have been proposed. We report a male infant with hydranencephaly and congenital vascular malformations (port wine stains, generalized nevus flammeus, anomalous retinal vessels, and absent internal carotid flow). Magnetic resonance imaging of the brain showed absence of most of the cerebrum except for small portions of the occipital cortex and thalami. Magnetic resonance angiography showed flow within the vertebral and basilar arteries without internal carotid intracranial flow above the internal carotid petrous and cavernous portion. This is a report of cutaneous and retinal malformations associated with hydranencephaly. Vascular malformations of larger vessels (e.g., webbing of the carotid arteries and an absent internal carotid arterial system) have been observed in other infants with hydranencephaly, and are proposed to lead to brain destruction. The case reported herein supports the role of primary vascular malformations in the development of some cases of hydranencephaly.

“…Taveras et al 36 reported that vessels were found only near the base of the skull, but Thelander et al 37 described a normal but stretched pattern of supratentorial vessels. Torre et al 3s found nearly normal vascular patterns of different types in the posterior fossa in all three cases they examined.…”

SummaryWe report a case of hydranencephaly with its clinical and morphological aspects. The origin of hydranencephaly is discussed. There is strong evidence of very early damage to the brain substance in this condition. Therefore this disease should not be regarded as a malformation. The diagnostic procedures are described and their values discussed.Since the first description of a patient by Curveilher 6 "with a normal head and face but without a brain" many authors have described such cases. Curveilher 6 coined the word "hydranencephaty", whereas other authors called it "cerebral agenesis" 34, "aplasia of the cerebral hemispheres" 15, or "a child without a forebrain" 3. Two years ago, we saw a child whose first clinical diagnosis was hydrocephalus on admission. Further clinical investigations and necropsy revealed hydranencephalus. Classification and IncidenceThe term "hydranencephaly" is agreed to describe an anomaly of the central nervous system consisting of nearly complete absence of the cerebral hemispheres but without anomaly of the covering layers. It has been called a destructive lesion by de Myer 7, and it has to be differentiated from disorders of size (i.e., macrocephalus), disorders of sulcation and migration (i.e., schizencephaly), disorders of diverticulation (i.e., holoprosencephaly), and disorders of closure (i.e., cranioschisis).

“…La Torre and Occhipinti reported three angiographic observations of hydranencephaly (one with postmortem correlation) where both the ACA and MCA were present but stretched ''as in the extreme degree of hydrocephalus''. 7 The distinctive criterion in their series was a lateral displacement of the MCA rather than the upward displacement, characteristic of hydrocephalus. However, if hydranencephaly is viewed as the extreme expression of a continuum of vascular lesions that ranges from ''a selective laminar loss of cortical nerve cells on one hand, to almost total destruction of the brain mass on the other'', 1 a parallel gradation in the degree of associated vascular injuries should not appear surprising.…”
