Cryptococcal choroid plexitis: rare imaging findings of central nervous system cryptococcal infection in an immunocompetent individual

R Kumari et al. Br J Radiol. 2010 Jan.

Abstract

Central nervous system (CNS) cryptococcosis is a common opportunistic fungal infection in immunocompromised patients, and the imaging findings differ from those in immunocompetent patients. Here, we present the imaging findings in an immunocompetent woman of a rare case of central nervous system cryptococcal choroid plexitis with trapped temporal horns, enlarged enhancing bilateral choroid plexuses and multiple intraventricular choroid plexus cysts.

Figure 1
(a) Axial T2 fluid-attenuated inversion-recovery and (b) coronal T2 weighted images show asymmetrically dilated and trapped temporal horns with periventricular extravasation of cerebrospinal fluid. Prominent perivascular spaces with adjacent oedema can be noted in the left basal ganglia.
Figure 2
Figure 2
(a) Axial T2 weighted image at the level of the lateral ventricular trigones reveals multiple bilateral intraventricular choroid plexus cysts and adjacent periventricular white matter oedema. (c) Contrast-enhanced axial T1 weighted image at the same level shows multilocular rim enhancement in both choroid plexuses. (c) Diffusion-weighted image (b-value _ 1000) shows no significant restriction of diffusion.
