In the present study patients with previously diagnosed MRI-negative temporal lobe epilepsy (TLE) on long-term video electroencephalography (VEEG) monitoring were re-evaluated with high resolution 3T MRI brain to look out for a skull base temporal lobe encephalocoele (TE). A total of 234 VEEGs were analyzed. TLE had been diagnosed in 104 patients based on semiology, ictal, interictal EEG data, and brain positron emission tomography (PET) studies. Of these, 99 patients had temporal lobe abnormality (78 had mesial temporal sclerosis, 8 had tumor, 3 had focal cortical dysplasia, and 10 had mixed pathology). Out of the five 1.5T MRI-negative TLE patients, two patients were diagnosed with TE on subsequent 3T MRI brain scans and one patient underwent electrocorticography-guided tailored resection for complete removal of epileptogenic tissue; with Engels class I seizure freedom at one year follow-up. We propose that TE should be carefully searched for, as a cause of refractory TLE, using high-resolution MRI sequences. [ABSTRACT FROM AUTHOR]

The article argues for the need to have awareness of the clinical implications of embryological variations in middle cerebral artery (MCA) anatomy, with reference to the case of a 51-year old woman with MCA with ruptured aneurysm, its pathophysiology and management. It cautions about the presence of rete anomaly with hemorrhagic stroke. Surgical management of rete anomaly include endovascular coil embolization, surgical clipping and intraoperative fluorescein videoangiography.

We report a characteristic pattern of ‘waist-like’ syringomyelia observed in three infants having mobile and reducible congenital atlantoaxial dislocation. The syringomyelia in at least two of these cases was diagnosed to be an intramedullary tumor. Following atlantoaxial fixation, all three patients had long-term recovery of their symptoms.

A 10-year-old child with transposition of the great arteries had multiple intracranial aneurysms. The child presented with pyogenic meningitis, and the investigations incidentally revealed numerous aneurysms involving both anterior and posterior circulation arteries. Angiography also revealed multiple fistulae between the internal and external carotid arteries. The child is under observation. The pathogenesis and management strategy of multiple intracranial aneurysms are discussed and the relevant literature is briefly reviewed. Copyright © 2006 S. Karger AG, Basel [ABSTRACT FROM AUTHOR]

Stereotactic procedures have been prevalent in neurosurgical practice for a prolonged time period. With the advent of new custom-made frames designed for morphologic and functional neurosurgical procedures, its extended use in the pediatric population is becoming increasingly popular. However, there is still a need for sophistication in design and instrumentation. We describe a novel method of a plaster of Paris mould for stereotactic frame fixation, which can be a useful adjunct during frame fixation. It primarily accounts for a remarkable variation in skull shapes and sizes seen in the pediatric population undergoing stereotaxy besides many other advantages. Copyright © 2005 S.

A 36-year-old male was admitted with a 10-year history of gradually progressive left ear hearing loss, diplopia and right hemiparesis. Magnetic resonance imaging showed a left lateral pontine enhancing tumour and an additional cerebellopontine angle epidermoid tumour in close proximity forming a collision tumour. On exploration, the epidermoid tumour and the intraaxial pontine glioma were completely resected. The literature on collision tumours is reviewed. [ABSTRACT FROM AUTHOR]

The article describes the case of a 1-month-old male infant who presented with two subcutaneous masses in close proximity to each other. The infant was born of a nonconsanguineous marriage and had a full-term normal delivery. A surgery was performed, and in the postoperative phase, the child was alert and had no motor or visual deficit. The wound also had healed well but eight months after surgery, the child reportedly died of chest infection.

We report a series of three patients with suprasellar arachnoid cysts who presented with a rare 'bobble-head doll' syndrome. The abnormal head movements improved after surgical evacuation of the cysts in all the three cases. Various pathophysiological mechanisms involved in the bobble-head doll syndrome are discussed. The literature on suprasellar arachnoid cysts is briefly reviewed. [ABSTRACT FROM AUTHOR]
