We evaluated clinical features of five cases of Toxoplasma encephalitis (TE) occurring in recent Haitian entrants into the United States. None of the patients had any underlying malignancy or known immunosuppressive therapy. Histopathologic findings of TE at autopsy were confirmed by peroxidase-antiperoxidase method. Four patients had an antecedent episode of disseminated tuberculosis and all five were receiving antituberculous therapy when neurologic manifestations of lethargy, seizures, and motor weakness first developed. These symptoms progressed into coma and death within 15 days. Peripheral lymphocytopenia was noted in all patients; three were anergic. Parenchymal lesions were identified by CT brain scans and total proteins were elevated in spinal fluid in all cases. TE appears to be a manifestation of the acquired immune deficiency syndrome in Haitians; it should be suspected in those with a febrile illness and multiple focal lesions of the central nervous system.

A 37-year-old woman with chronic myelogenous leukemia underwent allogeneic bone marrow transplantation with CD8-depleted marrow from an HLA-identical sister. On day 43 post-transplant, the patient developed a headache and became lethargic and tremulous. Magnetic resonance imaging (MRI) of the brain showed abnormal meningeal and superficial parenchymal enhancement anteriorly. The spinal fluid had an elevated protein level with normal glucose and a neutrophilic pleocytosis. At autopsy, Toxoplasma meningoencephalitis was seen. On review of the literature, headache and confusion at 1-2 months post-transplant are common presenting signs of central nervous system toxoplasmosis. The predominance of neutrophils in the spinal fluid in this patient probably reflects the meningeal component of the infection and is an unusual finding. The presentation of toxoplasmosis in marrow transplant recipients is quite pleomorphic, and a definite diagnosis is difficult to obtain antemortem. Empiric therapy with pyrimethamine and sulfadiazine should be considered for marrow transplant recipients with neurologic deficits for which there is no other apparent etiology.
