Abstract
Toxoplasmosis is caused by an intracellular protozoan called Toxoplasma gondii, and is seen worldwide. In patients with acquired immunodeficiency syndrome (AIDS), it constitutes the most common opportunistic central nervous system (CNS) infection. Magnetic resonance imaging (MRI) is the modality of choice for the evaluation of CNS involvement in these patients. In our case report, we described a 53-year-old male patient presenting with a right side hemiparesis and sensorial loss, who also had a history of AIDS. He underwent computed tomography examination where a hypodense left thalamic mass lesion was found. For further characterization, an MRI examination was performed and on T1 weighted images, a hypointense mass with a peripheral incomplete hyperintense rim at the left thalamic region was found, exhibiting a lamellar appearance on T2 weighted images. The mass showed slight peripheral contrast enhancement. Multivoxel MR spectroscopy demonstrated a conspicuous lactate peak. A biopsy procedure was performed and the pathological evaluation revealed cerebral toxoplasmosis.
