Cerebellopontine angle ganglioglioma: MR findings.
We present a case of cerebellopontine (CP) angle ganglioglioma in a young child with developmental delay and no trigeminal nerve symptoms. MR imaging demonstrated a mass of homogeneous low signal intensity in the left CP angle on T1-weighted images with no enhancement with gadolinium, and of relatively homogeneous high signal intensity on T2-weighted images.
متن کاملMR imaging of cerebellopontine angle and internal auditory canal lesions at 1.5 T.
The high-field, thin-section (3-5 mm) MR imaging characteristics of 49 cerebellopontine angle and internal auditory canal lesions were reviewed. The diverse abnormalities include 20 acoustic neurinomas, eight neurinomas of other cranial nerves (six involving the fifth cranial nerve and two involving cranial nerves IX-XI), seven meningiomas, five subdural fluid collections, four brainstem tumors...

متن کاملConstructive interference in steady state-3DFT MR imaging of the inner ear and cerebellopontine angle.
PURPOSE To assess the value of a three-dimensional Fourier transformation MR technique "CISS" (constructive interference in steady state) in imaging the inner ear. SUBJECTS We studied 50 normal inner ears (40 axial, 10 coronal) and 10 pathologic inner ears in 60 patients. RESULTS The cochlea, semicircular canals, and vestibulum were visualized in detail. Cranial nerve VII and the cochlear, ...
