[Total or partial ablation in surgery of acoustic neuroma].

The authors present the indications of partial or subtotal versus total removal of acoustic tumors and the removal prognosis of recurrence with methods of post surgical control.

[Tomodensitometry and/or meato-isternography in the diagnosis of small acoustic neuromas (author's transl)].

Tomodensitometry allowed us to discover smaller and smaller tumors in the cistern and even in the internal auditory canal. We report 5 cases, amongst others, where the tumor is visible in the canal and we show the conditions which are necessary to make the diagnosis. Nevertheless, lipiode meatocisternography is well tolerated if we use between 0.

[Contribution of radiography and gammagraphy to the monitoring of the development of psychoses].

The authors emphasize the frequency of intracranial tumors in psychiatric patients. They make a distinction between the rare cases of psychiatric patients with intracranial tumors and the even most-frequent cases of tumors that express themselves through psychiatric disorders. According to the authors, the most important detection-tests are the brain scan and, more recently, the EMI scan or tomodensitometer.
