GROWING CYST OF THE SEPTUM PELLUCIDUM IN EARLY INFANCY

We report a baby's development with expanding cyst of the septum pellu cidum. It was detectedaccidentally during diagnostic evaluation of epi leptic convulsions and psychomotoric retardation. The dramatic increas ing of the cyst was followed by cranial ultrasonography for ten months . The progression of clinical symptoms couldn't be explained because a fter drainage of the cyst, no improvement took place. MRT with Spectro scopy lead to the tentative diagnosis, Morbus Alexander. This couldn't be proved because no biopsy of the brain was performed against the de cision of the child's mother, nor postmortal (the child died at 20 mon ths).
