Acoustic neurinoma surgery in Belfast 1986-1989.
Forty-seven acoustic neurinoma tumours have been operated on in 46 patients in the years 1987-1989. This is a considerable increase over the prevalence in the preceding ten years. Twenty-six were classified as large tumours, 18 as medium and one was small. Surgical excision was complete in 16 and incomplete in 31 cases. Two patients died in the early postoperative period. Facial nerve function ...
متن کاملSmall cauda equina neurinoma detected by MR imaging.

Plain films of the lumbar spine were normal. On MR a small highintensity area was seen in the spinal canal of the fourth lumbar vertebra in spin-echo sequences (1200/60 (TR/TE]) (Fig . 1 A).

متن کاملMR enhancement of the internal auditory canal induced by tissue implant after resection of acoustic neurinoma.
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...
متن کاملEarly changes in volume and non-enhanced volume of acoustic neurinoma after stereotactic gamma-radiosurgery.
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 ...
متن کاملMicrosurgery for acoustic neurinoma--lateral position and preservation of facial and cochlear nerves.
Twenty two cases of acoustic neurinoma were operated on at Nagoya University Hospital or its affiliated hospitals by the first author. The ages of the patients ranged from 16 to 68 years and there were 13 females and 9 males. The sizes of the tumors were 4 cm or larger in diameter in 20 cases, i.e. 91 % of the total cases. Papilledema was observed in 13 cases (59 %) and hydrocephalus was found ...
