[In spinal symptoms remember toxoplasmosis].

A 4 weeks old girl presented a macrocephalus, elevated intracranial pressure and paralysis of both legs. The CT scan showed a hydrocephalus internus with stenosis of the aqueduct and periventricular calcifications. The cranial and spinal MRT scan revealed numerous lesions of the cerebral parenchyma and the spinal cord, which were detected after injection of Gadolinium Dimethylentriaminaceticacid (Gd DTPA). The serological examination confirmed the diagnosis of congenital toxoplasmosis.
