Neurenteric cyst in the region of conus medullaris

The authors present a case of 35-year-old male who presented with weakness and numbness of both lower limbs and urinary disturbance. Magnetic resonance imaging dorsolumbar spine was suggestive of neurenteric cyst in the region of conus medullaris. Complete surgical excision was performed. The relevant literature is discussed briefly

Outcome predicting factors in intracranial aneurysms: defining the complex aneurysms

The development of neurosciences has made the understanding and management of intracranial aneurysms better. It has been realized over the years that there may be a subgroup of patients who fare differently from the rest. The identification of factors which make the aneurysm different or complex may help in prognosticating patients. The aim of the current study was to identify such factors to assess how well they correlated with the outcome. Three-hundred-fourteen consecutive cases of spontaneous subarachnoid haemorrhage with intracranial aneurysms were retrospectively analyzed. Sixteen independent factors broadly categorized into three categories viz., patient related, radiological factors and surgery related factors were analyzed and their correlation with outcome studied. Univariate and multivariate analysis was done using logistic regression analysis and P values, and predictive values were determined. Five factors viz, WFNS grade 4-5, clinical vasospasm, smoking >/= 30 years, Fisher grade 3-4 and posterior circulation aneurysms were found to have highly significant association with poor outcome both using univariate and multivariate analysis. The clinical factors predominate and have more significant association with the outcome. The presence of factors viz, WFNS grade 4- 5, clinical vasospasm [DIND], smoking >/= 30 years, Fisher grade 3-4 and posterior circulation aneurysms were found to correlate with poor outcome and any of these factors could lead to poor outcome and are sufficient to label the patient as having a complex aneurysm

Bilateral astrocytomas: Clinicoradiological characteristics and endoscopic management

Bithalamic astrocytoma is an extremely rare condtion associated with progressive neurobehavioural syndrome and dementia. We report a 17-year-old boy who presented with headache and memory loss. His magnetic resonance imaging revealed large bithalamic, symmetrical, non-enhancing lesions with moderate hydrocephalus and tonsillar herniation. Magnetic responance spectroscopy revealed high choline and creatinine peaks. An endoscopic guided biopsy and ventriculoperitoneal shunt placement was followed by radiotherapy. The biopsy revealed grade II fibrillary astrocytoma. He was initially relieved of raised pressure symptoms but developed tremors and progressive neruobehavioural dysfunction and died after 3 years

Mixed oligodendroglioma - meningioma: a rare collision tumour

A case of a very rare intra-axial brain tumour, consisting of components - maliganant meniongioma, oligodendroglioma and astrocytoma in a 36-year-old man, is described. A review of literature regarding its pathogenesis is presented and a classification for such tumours is proposed to identify pathologically different subgroups among them as they do not belong to a homogenous variety and comparison of different subgroups in not worthwhile
