Unilocular toxoplasmosis simulating intracerebral tumor.

Toxoplasmosis is a common infection with increased incidence in patients suffering from AIDS. In this paper we report a rare case of toxoplasmosis without evidence of AIDS: The patient had a singular tumor-like lesion in the right parietal lobe in CT and MRI. In neurosurgical intervention no tumor was found. Finally, different histopathological examinations led to the diagnosis of toxoplasmosis. Diagnostic and therapeutic regimes in patients with suspect tumor-like lesions should be discussed.
