Cerebellopontine angle lipoma in asymptomatic patients: case report.
Lipomas represent approximately 0.15% of cerebellopontine angle tumors.1 Audiometric findings include unilateral or asymmetrical sensorineural hearing loss with low speech recognition index (SRI).2 Imaging procedures, particularly nuclear magnetic resonance (NMR), confirm the diagnosis.1--4 There is no image enhancement with gadolinium; in this scenario, special fat suppression sequences are pa...
متن کاملCT and MR Imaging Characteristics of Intravestibular and Cerebellopontine Angle Lipoma
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...
متن کاملMalignant Transformation of an Epidermoid Cyst in the Cerebellopontine Angle
Intracranial squamous cell carcinoma is extremely rare, with most of the cases arising from malignant transformation of an epidermoid or a dermoid cyst. The patient presented with facial weakness. Initial magnetic resonance imaging revealed a mass in the right cerebellopontine angle. A subtotal resection was performed via right retrosigmoid suboccipital approach. Histopathological findings were...
متن کاملCT and MR imaging characteristics of intravestibular lipoma.
BACKGROUND AND PURPOSE Intracranial lipomas are uncommon congenital malformations that most often are asymptomatic. A rare subset of intracranial lipomas arises within the vestibule of the inner ear, which can cause sensorineural hearing loss. We present the CT and MR imaging characteristics of lipomas within the vestibule of the inner ear and propose a pathogenetic mechanism for this malformat...
