“…This tortuous and dilated basilar artery, frequently attributed to atherosclerosis can cause symptoms very similar to that of a CPA tumour by direct impingement of the CPA. 13,14 In our study, the mean age of the 13 patients was 69 years old. Six of the 13 cases featured an ectatic basilar artery actually impinging on the CPA and this coincided with the side of symptoms in all six cases, suggesting a relationship.…”

The otolaryngologist who requests magnetic resonance imaging (MRI) scans to exclude cerebellopontine angle (CPA) tumours may discover incidental pathologies. We retrospectively reviewed the results of 644 consecutive MRI screening scans with the aim of identifying findings other than CPA tumours. Two hundred and eighty-nine (45 per cent) scans featured one or more anomalies or abnormalities, including CPA tumour (23, four per cent), vascular loop (30, five per cent), basilar artery ectasia (13, two per cent), multiple high signal areas (135,21 per cent), brain atrophy (52, eight per cent), sinus findings (56, nine per cent), middle ear/mastoid disease (34, five per cent), and a variety of other findings (39, six per cent) including clinically serious lesions (11, two per cent). The significance and management of these incidental findings is discussed. The majority were not clinically significant but the occasional presence of a serious incidental pathology should be borne in mind. Basilar artery ectasia and multiple high signal areas may be responsible for the symptoms investigated by MRI, and screening for cerebrovascular disease risk factors in such patients may be appropriate.

“…Although the lesions seldom bleed, pathological effects are produced both by ischaemic changes and by direct pressure; for example, the tortuous artery may intrude into the cerebello-pontine angle, mimicking an acoustic neuroma (Rao and Woodlief, 1979); or impinge on the floor of the third ventricle, producing hydrocephalus and dementia (Greitz et al, 1969).…”

“…One recent study reported that vertebrobasilar dolichoectasia was present in 6.4% of patients with cerebral infarction. 113 ICVA aneurysms may compress the medulla resulting in hemiparesis and other deficits. 106,109 Occipital-nuchal pain is common, and cranial nerve damage may result in seventh and eighth cranial nerve palsies, hemifacial spasms, tinnitus, deafness, vertigo, trigeminal pain, and hypoglossal paralysis.…”
