RESUMO
Transcranial Doppler (TCD) sonography is emerging as a new ultrasonography technology to look at the interaction between the brain parenchyma and perfusion during cerebrovascular accident. Before TCD sonography the vasospasm following subarachnoid haemorrhage could only be diagnosed either clinically or by invasive method ie, angiography. TCD has been proved as a wonderful non-invasive, repeatable, beat-by-beat, non-expensive technique for detection and follow-up of vasospasm after subarachnoid haemorrhage. In the present series 12 patients suspected to have vasospasm after subarachnoid haemorrhage were confirmed and monitored with the help of TCD. Most of the patients were clinically presented with increasing headache and altered sensorium. It is noticed that vasospasm following subarachnoid haemorrhage has a typical course, which has increasing trend after 4th day of subarachnoid haemorrhage and declining trend after 14th day onwards. Six out of 12 patients were in moderate grade of vasospasm, 2 out of 12 were in severe grade and 4 out of 12 were mild grade of severity.

A prospective study of 31 percutaneous vertebroplasty procedures (PVP) in 22 patients treated during January 2000 to December 2001 is presented. PVP was performed using polymethylmethacrylate (PMMA) to treat vertebral collapse due to osteoporosis and vertebral metastasis, to obtain analgesia and spinal stabilization. We analyze the efficacy and complications related to the procedure. PVP is a safe, effective and a daycare surgery. It can be performed under local anesthesia and has minimal and manageable complications.

This is a case presentation of a young patient with an intracranial space-occupying lesion following multiple episodes of generalised tonic clonic seizures for the last 20 years. Such a long latency period between the onset of fits and the discovery of an intracranial lesion is highly unusual in malignant brain tumours. This lesion was excised completely and proved to be a primary lesion of the brain - fibrosarcoma. These rare tumours of mesenchymal origin in the central nervous system are very rare.
