Solitary hypothalamopituitary toxoplasmosis abscess in a patient with AIDS

L Legrand et al. AJNR Am J Neuroradiol. 2011 Jun-Jul.

Abstract

Toxoplasmosis is a disease caused by an obligate intracellular protozoal parasite, Toxoplasma gondii. It is the most common cause of focal brain lesions in patients with AIDS. The imaging features and endocrine disorders of CNS toxoplasmosis in patients with AIDS are reviewed.

MR imaging at diagnosis. A, Sagittal contrast-enhanced T1-weighted image shows a ring-enhancing lesion of the hypothalamopituitary axis. B, Axial contrast-enhanced T1-weighted image shows the lesion centered on the hypothalamus and the optic chiasm. C, Axial FLAIR image demonstrates marked vasogenic edema that involves the hypothalamus and mesencephalon.

MR images obtained after treatment. A and B, Sagittal and axial contrast-enhanced T1-weighted images show complete regression of the abscess. C, Axial FLAIR image demonstrates a nearly complete regression of the edema.
