A case of cerebral toxoplasmosis in a pregnant non-immunocompromised patient.

Cerebral toxoplasmosis, a disease of immunocompromised individuals, is rare in immunocompetent persons. We present a case of cerebral toxoplasmosis in a non-immunocompro-mised pregnant woman. Her imaging studies revealed a mass lesion involving the right basal ganglia, periventricular grey matter, midbrain and pons suggesting a neoplastic pathology along with hydrocephalus. She underwent an endoscopic third ventriculostomy and biopsy of the lesion. Postoperatively her consciousness improved as the hydrocephalus was relieved. After a thorough gynaecological examination she gave birth to a healthy child via normal vaginal delivery. The histopathology examination of biopsy suggested an inflammatory pathology. Serological studies for toxoplasmosis were positive. After 6 weeks of anti-toxoplasma treatment follow-up imaging showed a significant decrease in the size of the lesion.
