“…In 2007, Shim et al 17 presented a case of unilateral profound sensorineural hearing loss due to a venous malformation of the internal auditory canal. As expected, no malformations of the internal auditory canals were detected in our patient and therefore we had to focus on the possible effects of CCSVI on the outflow of the inner ear, that is completely drained by the vein of the cochlear aqueduct.…”

“…The neurological symptoms were caused by mechanical compression in 32.7% of all cases of symptomatic DVAs with hydrocephalus, tinnitus, brainstem deficits, facial hemispasm, and trigeminal neuralgia being the most common presenting symptoms. 4,8,28,30,31,34,44,45 Obstruction of the ventricles has not only been described for DVAs, but also for dilated drainage veins of an AVM. Potential sites for obstruction are at the level of the interventricular foramen (here related to dilated thalamostriate veins) or at the aqueduct (due to a dilated vein of Galen or transparenchymal venous collectors).…”

Background and Purpose-Although it is generally accepted that developmental venous anomalies (DVAs) are benign vascular malformations, over the past years, we have seen patients with symptomatic DVAs. Therefore, we performed a retrospective study and a literature study to review how, when, and why DVAs can become clinically significant. Methods-Charts and angiographic films of 17 patients with DVAs whose 18 vascular symptoms could be attributed to a DVA were selected from a neurovascular databank of our hospital. MRI had to be available to rule out any other associated disease. In the literature, 51 cases of well-documented symptomatic DVAs were found. Pathomechanisms were divided into mechanical and flow-related causes. Results-Mechanical (obstructive or compressive) pathomechanisms accounted for 14 of 69 symptomatic patients resulting in hydrocephalus or nerve compression syndromes. Flow-related pathomechanisms (49 of 69 patients) could be subdivided into complications resulting from an increase of flow into the DVA (owing to an arteriovenous shunt using the DVA as the drainage route; nϭ19) or a decrease of outflow (nϭ26) or a remote shunt with increased venous pressure (nϭ4) leading to symptoms of venous congestion. In 6 cases, no specific pathomechanisms were detected. Conclusions-Although DVAs should be considered benign, under rare circumstances, they can be symptomatic. DVAs, as extreme variations of normal venous drainage, may represent a more fragile venous drainage system that can be more easily affected by in-and outflow alterations. The integrity of the DVA needs to be preserved irrespective of the treatment that should be tailored to the specific pathomechanism. (Stroke. 2008;39:3201-3215.)

“…A venous angioma arising within the IAC and expanding to the brainstem has caused a unilateral profound sensorineural hearing loss [63]. Hearing loss in this outpatient was incidentally discovered in the right ear.…”

“…T2-weighted MRI revealed hypointense large tubular structures of the IAC that extended to the contralateral side of the brainstem across the right cerebellopontine angle area and multiple branching structures in the cerebellar hemispheres with intense contrast enhancement were consistent with venous angioma. Observation of the lesion was recommended until other intracranial complications developed [63]. Venous angiomas are low-flow, low-resistance lesions that are less likely to hemorrhage, the estimated overall risk of which is 0.22% per year [64].…”

Auditory Dysfunction in Patients with Cerebrovascular Disease

Auditory dysfunction is a common clinical symptom that can induce profound effects on the quality of life of those affected. Cerebrovascular disease (CVD) is the most prevalent neurological disorder today, but it has generally been considered a rare cause of auditory dysfunction. However, a substantial proportion of patients with stroke might have auditory dysfunction that has been underestimated due to difficulties with evaluation. The present study reviews relationships between auditory dysfunction and types of CVD including cerebral infarction, intracerebral hemorrhage, subarachnoid hemorrhage, cerebrovascular malformation, moyamoya disease, and superficial siderosis. Recent advances in the etiology, anatomy, and strategies to diagnose and treat these conditions are described. The numbers of patients with CVD accompanied by auditory dysfunction will increase as the population ages. Cerebrovascular diseases often include the auditory system, resulting in various types of auditory dysfunctions, such as unilateral or bilateral deafness, cortical deafness, pure word deafness, auditory agnosia, and auditory hallucinations, some of which are subtle and can only be detected by precise psychoacoustic and electrophysiological testing. The contribution of CVD to auditory dysfunction needs to be understood because CVD can be fatal if overlooked.
