BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/ bcr-2013-201253 DESCRIPTION A 6-year-old boy presented with a 6-month history of worsening gait, abnormal eye movements and head tilt. Neurological examination revealed papilloedema, gaze-evoked nystagmus, decreased rightsided hearing, decreased sensation in the right V1 tr...

Endolymphatic sac tumours (ELST) are aggressive papillary tumours of the temporal bone. The name was finally determined after the endolymphatic sac was determined as the site of their origin. They should be considered in patients with tumours eroding the petrous part of the temporal bone, extending to the cerebellopontine angle or other adjacent structures. These very rare tumours in the genera...

A case of bilateral endolymphatic sac tumours is reported. In a patient with von Hippel-Lindau syndrome, tumour growth in the right cerebellopontine angle caused deafness. The tumour was removed and classified as a metastasis from a thyroid carcinoma. However, on thyroidectomy no primary neoplasm could be found. Eight years later a similar tumour was operated on in the left petrosal bone. Histo...

Here, we report psychotic symptoms together with a right cerebellopontine-angle lesion. A37-year-old female patient presented with a trigeminal Schwannoma occupying the right cerebellopontine angle. Her psychotic symptoms included auditory hallucinations and delusions of persecution. T1- and T2-weighted images on magnetic resonance imaging (MRI) revealed hyperintense and hypointense areas in th...

It is estimated that 10% of intra-cranial tumours are localized in the cerebellopontine angle and internal auditory canal and early symptoms of the different histological forms are almost identical. Acoustic neuroma account for 90% and meningioma for 5-10% of these tumours, while a small percentage of rare tumours exist, the most frequent being epidermoid cyst, also known as congenital choleste...

PURPOSE To compare constructive interference in the steady state (CISS) three-dimensional Fourier transform (3DFT) MR imaging with contrast-enhanced T1-weighted spin-echo MR imaging for accuracy in detecting acoustic schwannoma. METHODS One hundred twenty-five consecutive patients with possible acoustic schwannoma were examined. The accuracy of CISS-3DFT MR imaging in detecting abnormalities ...
