The clinical presentation of trigeminal schwannoma depends on the size and location of the tumor. Typical symptoms include ipsilateral hypesthesia, headache, and facial pain. Diagnosis is usually made according to clinical features and imaging findings. The most definitive treatment for TSs is ...
This situation and sequence of events is important in considering a surgical approach (excision of trigeminal schwannomas, extradural anterior petrosectomy, surgery of petroclival meningiomas) to Meckel's cave in which the lateral wall of the cavernous sinus (CS) is to be elevated and Meckel's ...
There are also rare reports of the coincidence of trigeminal and glossopharyngeal neuralgia, sometimes resulting from multiple sclerosis or vestibular schwannoma. Differential Diagnosis Trigeminal neuralgia is so characteristic that it does not really have a differential diagnosis. Glossopharyngeal neuralgia...
We present the MR imaging, CT, and clinical findings of a patient with malignant schwannoma of the trigeminal nerve. Local tumor recurrence is frequent and... JA Stone,H Cooper,M Castillo,... - 《Ajnr American Journal of Neuroradiology》 被引量: 358发表: 2001年 Symptoms and signs related ...
Cerebellopontine angle tumors (ie, acoustic neuroma/vestibu- lar schwannoma, meningioma, cerebellar astrocytoma) and multiple sclerosis plaques are the most commonly identified abnormalities. Trigeminal reflex testing, including the blink reflex, has a relatively high accuracy for identifying patients with...
From their common site of origin, trigeminal schwannomas sometimes extend posteriorly into the posterior fossa or anteriorly via skull base foramina to show schwannoma's classic "dumbbell" configuration. Diagnostic Delay: Although symptoms are sometimes present many months before diagnosis, tumor size ...
tumor recurrenceObjective: Trigeminal schwannomas (TS) are rare, when compared to vestibular schwannomas. The present study aims to analyze the clinical characteristics and surgical strategies of TS via the retrospective analysis of the clinical data of 43 patients. Methods: The clinical information ...
Background Intracranial schwannomas are most commonly associated with the vestibulocochlear nerve, often leading to hearing loss, tinnitus, and vestibular dysfunction. Much less often, a schwannoma can arise from the trigeminal nerve which can lead to facial pain, numbness, and weakness.Evans, Lauran...
13鈥 21 Jefferson 6 presented a classification scheme for trigeminal schwannomas that categorized these tumors according to location. Three distinct types are: middle fossa type (type A); posterior fossa root type (type B), where the tumor is in front of the brainstem; and dumbbell-shaped ...
Skull base tumorTrigeminal schwannomaSchwannomas of the trigeminal nerve are benign, uncommon tumors that account for 0.07-0.36% of all intracranial neoplasms and 0.8-8% of intracranial schwannomas [ 1,2 ]. They usually present with pain and paresthesia of the face as initial symptoms, whereas ...
