SAMALVIDES, Susan K. et al. Three clinic-radiological forms of neurological compromise by congenital toxoplasmosis. Rev Neuropsiquiatr [online]. 2014, vol.77, n.3, pp.188-195. ISSN 0034-8597.

Congenital toxoplasmosis is a prevalent disease among intrauterine infections. We describe three cases with different forms of neurological compromise. Case 1: fetus with hydrocephalus detected at 36 weeks , whose mother had positive antibodies (Ig M: 2.26 IU / ml), the patient was born by caesarean section  and  physical examination showed macrocephaly, uveitis, hepatosplenomegaly , hypotonia, incomplete Moro reflex and weak suction, IgM 0.95 IU / ml , CSF with viable tachyzoites were observed and 1204 mg protein / dl. Case 2: newborn lethargic at birth, with chorioretinitis, left hemiparesis, hypotonia, hyporeflexia and right mydriasis (Weber syndrome), CSF leukocytes showed 52 mm3, glucose 63mg/dl and protein 300 mg/dl,  IgM 1.9 IU/ml  and multiple  parenchymal lesions. Case 3: patient 3 months old, malnourished , with large fontanelle, axial hypotonia, appendicular hypertonia and hyperreflexia, IgM 2.1 IU/ml, hydrocephalus due to aqueductal stenosis and  diffuse parenchymal lesions . In all of them  the  treatment schedule was sulfadiazine, pyrimethamine, folinic acid and prednisone. Ventricular drainage was placed for children with hydrocephalus. Deafness, visual acuity loss and developmental delay was observed at follow up. We conclude that congenital toxoplasmosis can have different forms of neurological presentation depending to infestation period, inoculum and host immune response.
