Lesions in AIDS patients
Figure 2 presents MR spectra obtained for a brain lesion and the
contralateral region of an AIDS patient. In Figure 3, published spectra
(1) of common brain lesions (toxoplasmosis, lymphoma and progressive
multifocal leucoencephalopathy) in AIDS patients are presented in
addition to the spectrum of the healthy contralateral region. It is
obvious, comparing Figures 2 and 3, that the diagnosis of the patient
studied is toxoplasmosis.
Fig. 2. Brain spectra of an AIDS patient
recorded on the lesion (left) and in the contralateral area (right).
The lesion spectrum is compatible with toxoplasmosis (Fig. 3).
Fig. 3. Spectra of common brain lesions
observed in AIDS patients (toxoplasmosis, lymphoma and progressive
multifocal leucoencephalopathy) as well as the spectrum of the healthy
contralateral region (1).
