A group of 119 cases of cerebellopontine angle (CPA) tumours was studied looking at the pathological composition, relative incidence of tumour types, their radiological features and the pathological-radiological correlations. Tumours with preoperative radiological diagnosis and verified pathologically were analyzed. Histopathologically the material consisted of 77 schwannomas and 42 non-acousti...

The coexistence of schwannoma and meningioma in the same cerebellopontine angle (CPA) is uncommon. Especially, the presence of a single mixed tumour composed of demarcated or intermingled components of schwannoma and meningioma tissue is extremely rare. Such a phenomenon is mainly reported in a patient with NF2 or with history of previous irradiation. We present two cases of simultaneous occurr...

Intraaanial epidermoid tumourS. which are indusion tumours of the central nervous system. are congenital neoplasms that grow through desquamation of keratin. cholesterol. and cellular debris. They constitute 0.5 to LS per cent of all brain tumours (15).The expansion usually conforms to available subarachnoid spaces (2. 15).The most common intraaaniallocations are the parachiasmal and cerebellop...

Trigeminal neuralgia is a recognized complication in patients with intracranial tumours affecting the trigeminal nerve. This case report describes an epidermoid tumour at the cerebellopontine angle in a middle-aged man with otherwise classical unilateral trigeminal neuralgia. The case highlights the difficulties of diagnosis and the importance of a multidisciplinary approach when trigeminal neu...

An area of special challenge, is the cerebellopontine angle (CPA), which is formed between the brain stem and the cerebellum, because of the close proximity of major nerve trunks and blood vessels. Acoustic tumours account for approximately 80% of CPA tumours, and surgery involves risk primarily to the facial nerve the motor nerve of facial expression, and the cochlear nerve the sensory nerve o...

Accepted 18 December 2017 DesCripTion A 24-year-old woman presented with gradual-onset left-sided hearing loss, progressive diminution of vision, headache and unsteadiness of gait. Comprehensive clinical evaluation revealed a left-sided lower motor neuron type of facial nerve palsy (figure 1), bilateral papilloedema, sensory loss in the distribution of ophthalmic branch of the left trigeminal n...

intracranial lipoma is an uncommon entity. a rare type of tumor in the internal auditory canal (iac) and the cerebellopontine angle (cpa) is lipoma. there are a few case reports in the literature related to intravestibular lipoma. herein, we report a case of lipomas within the cerebellopontine angle and vestibule of the inner ear in a patient with tinnitus and dizziness. the patient was evaluat...

Seven cases of aneurysm of the vertebral and basilar arteries, in which the clinical features suggested a diagnosis of posterior fossa tumour, are presented. Their clinical manifestations and the difficulties of diagnosis are discussed. These lesions may mimic cerebellopontine angle tumours or brain-stem gliomas, or, less commonly, the picture is one of a compressive lesion at the foramen magnu...
