An unusual cause of isolated secondary ovarian failure due to cerebral toxoplasmosis in an African woman with AIDS.

Primary ovarian failure is common. However, isolated secondary ovarian failure due to gonadotrophin deficiency is rare. A few cases of isolated gonadotrophin deficiency, due to congenital cerebral toxoplasmosis, have been described in children. We report the case of a 34-year-old African woman positive for HIV, who developed secondary amenorrhoea following the successful treatment of cerebral toxoplasmosis. Investigations revealed that she developed an isolated gonadotrophin deficiency due to pituitary lesion. The rest of the pituitary function dynamic tests were normal.
