This paper analyzes the results of surgical treatment of 73 patients with drug addiction. They were treated by lesions in the anterior cingulum.

Results of surgery indicate this procedure as the most promising one for cure of drug addiction.

We present a case of intramedullary glioependymal cyst with a filar lipoma in an infant. The clinical features, terminology and pathogenesis are discussed. Many varieties of spinal cysts have been described. It is now believed that simple ciliated or goblet-containing intracranial and intraspinal cysts are endodermal rather than glioependymal in origin. The diagnostic criteria, too, have been defined. Although many of these lesions are developmental in origin their association with other congenital anomalies is rare.

A case of intramedullary abscess of the spinal cord in a child aged 3 years is reported. Successful outcome depends on early diagnosis and aggressive management.
