Author’s address: P. H. Schmidt, M. D., Diaconesseninrichting Bronovo, Den Haag (Netherlands) The neurinoma of the facial nerve is a rare tumor. The first case was described by Schmidt in 1930. The fact that 30 years later Miehlke could collect only 42 cases of intratemporal neurinoma of the facial nerve justifies the description of another case. A 13-year-old girl had noticed a left side facia...

Neurinomas originating from intercostal nerve roots can grow both inside and outside of the spinal canal, forming dumbbell-shaped tumors. Such a neurinoma was discovered at the Th3 and Th4 levels in a 73-year-old woman during evaluation for breast cancer surgery. Magnetic resonance images (MRI) showed spinal cord compression by the tumor despite lack of neurologic symptoms. The tumor was resect...

A case of neurinoma of the pharynx in a 58-year-old woman was reported. The patient complai. ned of dysphagia, sensation of the lump in the throat and speech disorder at the time of admission. Radical operation under general anesthesia was first indicated in this case, using an endotracheal tube with the patient in the prone position, and the removal was effected by oral route. The tumor measur...

Neurinoma or schwannoma is an uncommon benign tumor that arises primarily from the nerve sheath of Schwann cells. About 25% has been reported in head and neck region extracranially, but only 1% in the intraoral origin. Intraorally, the tongue is the most common site followed by the palate, floor of the mouth, lips and buccal mucosa. In review of literature, intraoral schwannoma of the lingual n...

Background and Importance: Our learning curve during two decades of neurosurgical practice has been changed from an abstractive to a more meaningful and conductive state. In cases of fifth nerve neurinoma, pre-operative anatomopathologic diagnosis could lead us to a pre-planned program during and after the surgery to get the safe surgical result. Case Presentation: Representation of two comp...

A neurinoma was confirmed in the tympanum and attic of the reoperative case of chronic otitis media of 53-year-old female, whose right middle ear surgery 12 years ago had facial nerve paralysis of the same side immediately after the operation. The granulation tissue filling the tympanum and the attic was solid and thick. The anterior part of the attic wall was destroyed and the dura of the midd...

Neurinomas are common space-occupying lesions located in the spinal canal. Many reports concerning their clinical characteristics, diagnoses, treatments, and operative results have been published. Some case reports have discussed spinal neurinomas located at the cauda equina level. However, there is little information on their natural history. Here, we report a case of spinal neurinoma located ...

UNLABELLED Vestibular schwannoma, also known as acoustic neurinoma, is the most frequent tumor of the cerebellopontine angle, and represents 9% of all intracranial tumors. CASE REPORT The authors report a case of sudden deafness with unilateral tinnitus. The patients responded to therapy with Prednisone and Pentoxifylline after the diagnosis of acoustic neurinoma by imaging exams. DISCUSSIO...

PURPOSE We studied intrameatal changes in MR enhancement induced by free-tissue implant over time after surgery for acoustic neurinoma. METHODS Twenty-one patients were examined by MR imaging after suboccipital resection of an acoustic neurinoma. Precontrast and postcontrast MR images were obtained within 3 days after surgery (early MR images), then 6 weeks (intermediate MR images) and 6 mont...

The effectiveness of stereotactic gamma-radiosurgery for treating acoustic neurinoma was evaluated by measuring the volumes of the tumor, non-enhanced tumor, and cerebellar edema in 13 patients with acoustic neurinoma who were followed up for 9 to 15 months (median 12.7 mos) after treatment. The tumor volume and non-enhanced volume tended to reach a maximum after 6 months, and cerebellar edema ...
