“…Longterm followup of patients treated with this method is still needed to evaluate the exact role of radiosurgery in the late control of these lesions. 1,[17][18][19]31,35,36,37,44 It is evi dent, however, that no patient will ever be cured of this benign tumor with radiotherapy or radiosurgery. Several contemporary series have demonstrated no deaths or major surgical complications with radical re moval of TSs.…”

Object The authors provide a detailed review of the surgical management of trigeminal schwannomas (TSs) and also discuss the best surgical approach based on the surgical anatomy and tumor extension. Methods A series of 17 patients with TSs who were surgically treated between 1987 and 2008 at the authors' institution is reported. The lesions were small (< 3 cm) in 2, medium (between 3 and 4 cm) in 5, large (> 4 cm) in 6, and giant (> 5 cm) in 4 cases. Preoperative symptoms included trigeminal hypesthesia (53%), facial pain (53%), headaches (35.3%), hearing impairment (17.6%), seizures (17.6%), diplopia (11.8%), ataxia (11.8%), and hemiparesis and increased intracranial pressure with papilledema (5.9%). The mean follow-up duration was 10.5 years (121.6 months), with an average of 0.8 patients per year. Results Total tumor excision was possible in 16 patients, with no surgery-related deaths. Postoperative trigeminal anesthesia was observed in 7; trigeminal motor function was preserved in 7. Two developed cerebrospinal fluid leakage, 2 presented with mild facial palsy, and 1 patient with neurofibromatosis Type 2 had recurrence of the tumor, which was uneventfully removed. Of the 9 who reported facial pain, only 1 remained symptomatic postoperatively. Conclusions The best treatment for TSs is complete microsurgical removal. Postoperative preservation of trigeminal nerve function is possible when resection of the lesion is performed at well-established skull base neurosurgical centers. Although good results have been reported with radiosurgery, no cure can be obtained with this therapeutic modality. Instead, this treatment should be reserved only for nonresectable and residual tumors within the cavernous sinus.

“…Following the diagnosis, and taking into account the patient's age and locations of tumors, gamma knife radiosurgery was considered therapy of choice in the present case. Long-term follow up demonstrated gamma knife radiosurgery to off er a high rate of tumor control, preservation of multiple nerve functions, and good quality of life in patients with both vestibular schwannoma and trigeminal schwannoma 10,11 . Th e presented case is unique because it shows a rare phenotype of multiple schwannomas (unilateral vestibular schwannoma and trigeminal schwannoma) in a non-NF2 patient with no other stigmata of neurofibromatosis.…”

SUMMARY -Schwannomas are benign encapsulated tumors arising from the sheaths of peripheral nerves. Th ey present as slowly enlarging solitary lumps, which may cause neurological defects. Multiple schwannomas in non-neurofi bromatosis type 2 patients are extremely rare. We report a case of a 60-year-old female patient, without any family history of neurofi bromatosis or schwannomatosis, presented with trigeminal neuralgia and progressive facial nerve palsy. Magnetic resonance imaging revealed the presence of acoustic schwannoma involving facial nerve and trigeminal schwannoma of the cisternal part of the nerve involving gasserian ganglion (Meckel's cave). After gamma knife radiosurgery, trigeminal neuralgia was relieved completely with improvement of facial nerve palsy.

“…Several contemporary series have demonstrated no deaths or major surgical complications with radical removal of tumors in the Meckel's cave and gasserian ganglion (6,21). For small, nonresectable and residual tumors, good results have been reported with radiosurgery (17,18). Long-term follow-up of patients treated with this method is still needed to evaluate the exact role of the radiosurgery in the late control of these lesions (17,18).…”

Abstract:Objectives: Metastases in Meckel's cave are a rare tumor entity, but they should be considered in patients with a known primary malignancy and who complain of trigeminal neuralgia. Methods: The case of a patient with a left trigeminal neuralgia caused by a metastatic tumor involving the Meckel's cave and Gasserian ganglion is reported. Preoperative symptoms included headache, trigeminal hyperesthesia and facial pain. Results: The patient underwent microsurgical resection of the tumor, obtaining a histological diagnosis and a resolution of the pain. Trigeminal motor function was preserved. Conclusion: The best treatment for tumors of Meckel's cave, including metastases, is complete microsurgical removal. Although good results have been reported with radiosurgery, this treatment should be reserved only for nonresectable and residual tumors.

Gamma-knife radiosurgery in the treatment of trigeminal schwannomas

Abstract: For patients with small to moderate size trigeminal schwannomas, gamma-knife radiosurgery is associated with good tumour control and a minimal risk of adverse radiation effects.
