..Thalamic tumours account for approximately 1% to 5% of all brain tumours, and are usually unilateral astrocytoma and frequently affect children. Bilateral thalamic tumours are very rare neoplasm, yet their actual incidence is unknown...

..They commonly occur in young adults with a peak incidence corresponding to the fourth decade of life...

..Spontaneous acute SDH secondary to aneurysm rupture has been rarely reported. We suggested that timely SDH removal and aneurysmal clipping surgery should be performed in such patients, including those in poor neurological condition...

..Chondrosarcomas are the second commonest type of bony tumors, although they are not commonly found to be vertebral. They may originate in healthy bone or develop in a cartilaginous lesion with sarcomatous degeneration...

..Osteomuscular hydatidosis is an uncommon disease in which the spine is involved in 50% of the cases. Preoperative diagnosis is difficult in our setting because of its low incidence and the absence of specific radiological criteria...

..The spontaneous resolution of herniated lumbar discs is a well-established phenomenon. The authors present a case of spontaneous regression of a herniated lumbar nucleus pulpous in a patient with radiculopathy...

..Meningiomas account for 15 to 45% of spinal cord tumors. They are more frequent in females and have low recurrence rate due both to their low tendency for regrowth and to their prevalence in the aged population...

..CONCLUSIONS: Although generally speaking these disorders are not usually serious, they must be borne in mind so that adequate treatment can be indicated...

..A variety of monitoring techniques and devices are available, each offering advantages and disadvantages. Analysis of large populations has never been performed...

..The incidence of multiple intracranial meningiomas varies from 1 to 10% in different series. In this article we report our experience with the diagnosis and treatment of multiple meningioma...
