Item Chordoid meningioma: A report of two cases(NEUROLOGY INDIA, 2003)Chordoid meningioma is an uncommon histopathological variant of meningioma. We report 2 cases of chordoid meningioma occurring in adult patients.Item Intramedullary spinal cord glial tumours: Management philosophy and surgical outcome(MINIMALLY INVASIVE NEUROSURGERY AND MULTIDISCIPLINARY NEUROTRAUMATOLOGY, 2006) Nair, S; Menon, G; Rao, BRM; Rajesh, BJ; Muthurethinam, T; Mathew, A; Easwer, HV; Bhattacharya, RNA retrospective analysis of 88 consecutive cases of intramedullary glial tumours, which constituted 58% of 149 cases of intramedullary lesions surgically managed over a 22-year period, is presented. Fifty-six astrocytomas and 32 ependymomas formed the group, which comprised 55 males and 33 females. While majority of the astrocytomas were in the cervical or cervicodorsal location (70%), it was almost equally distributed between the cervical and conus regions in 23 cases of ependymomas. The management philosophy has changed over the years from biopsy to total removal for ependymomas and a generous inside out decompression in case of astrocytomas. While only a biopsy or decompression was done in 35 of the earlier patients of astrocytomas a radical removal (subtotal in 18 and total in 3) could be achieved in 21 of our recent patients. We could achieve total resection in all the last 17 patients of ependymomas. Low grade astrocytomas radically removed and all ependymomas were not given radiotherapy. Out of the 39 patients of astrocytomas who are in follow up, 13 have improved, 19 remaining static and 7 have deteriorated. While only three of the 25 patients of ependymomas on long term follow up have deteriorated 18 have improved and 6 are remaining static. Conclusion: Although total resection of ependymomas have become a procedure with good functional results in most hands, a radical resection can be achieved with long term stabilisation of neurological deficits in majority of astrocytomas.Item Natural history of seizures after temporal lobectomy: An actuarial approach(EPILEPSIA, 2005) Panda, S; Radhakrishnan, K; Sylaja, PN; Cherian, J; Rao, MB; Rao, BRM; Radhakrishnan, VV; Sarma, PSItem Petroclival-Premeatal Meningiomas: Reverting back to conventional retrosigmoid approach(8TH ASIAN CONGRESS OF NEUROLOGICAL SURGEONS (ACNS 2010), 2010) Nair, S; Rao, BRM; Menon, GA retrospective analysis of 113 cases of petroclival-premeatal meningiomas surgically managed in their institute from 1st Jan 1990 till 1st November 2010 was carried out to see the outcome with various approaches. While the tumor resection was carried through an anterolateral/lateral route in 31(28.5%), it was through a combined posterior subtemporal /pre or trans-sigmoid (posterior petrosal) in 24(22%) & retrosigmoid supra-paracerebellar route in 51 cases (44%). In three cases with extra cranial extension to infratemporal area, a modified Fisch approach was used. Four patients who were in poor clinical condition had only a CSF diversionary procedure. The percentage of these tumors operated by conventional retrosigmoid route has increased in the later part of the series thus proving that in many of these tumors without significant middle fossa extension, it is not necessary to use complex and time consuming skull base approaches which in themselves can cause morbidity. The tumor could be radically removed in 76 patients (67%), subtotally in 26 (23%) and decompression only in 7(6.%). Six patients had tumor excision in two stages. There was an operative mortality of 8.5% (10 cases). Out of the 78 patients on long term follow up 52 are independent. Six out of the eight patients who had symptomatic recurrence were re-operated.
