“…These structures are manifested in MRI as defined: rounded foci with regular contours, low to intermediate signal in T1, hyperintense signal in T2 and low signal in FLAIR in the predominant topography of the nuclei of the base and brainstem. The enhancement by gadolinium is minimal or absent, as well as perilesional edema [1][2][3][4].…”

Cryptococcosis is a pathology caused by a fungus called Cryptococcus neoformans. It represents the most common fungal infection of the central nervous system in individuals with acquired immunodeficiency syndrome, affecting 11% of individuals in this group. In immunocompromised patients, the usual neurological impairment is subacute meningitis associated with multifocal dilatation of Virchow-Robin perivascular spaces. Immunocompetent patients are more frequently affected in the parenchyma with formation of fungal abscesses called cryptococcomas. Magnetic resonance imaging is more sensitive in cases of cryptococcal meningitis, but in immunocompromised cases, a normal examination is possible due to a lack of inflammation. Meningeal enhancement is demonstrated on FLAIR and T1-weighted images with contrast. There are four described imaging patterns: cryptococcomas, enlarged perivascular spaces, leptomeningeal and parenchymal nodules, and a mixed pattern. Many other conditions may simulate these radiological findings, making it necessary to be aware of them.

MRI imaging features of HIV-related central nervous system diseases: diagnosis by pattern recognition in daily practice

With the advent of antiretroviral therapy (ART), the prognosis of people infected with human immunodeficiency virus (HIV) has improved, and the frequency of HIV-related central nervous system (CNS) diseases has decreased. Nevertheless, mortality from HIV-related CNS diseases, including those associated with ART (e.g., immune reconstitution inflammatory syndrome) remains significant. Magnetic resonance imaging (MRI) can improve the outlook for people with HIV through early diagnosis and prompt treatment. For example, HIV encephalopathy shows a diffuse bilateral pattern, whereas progressive multifocal leukoencephalopathy, HIV-related primary CNS lymphoma, and CNS toxoplasmosis show focal patterns on MRI. Among the other diseases caused by opportunistic infections, CNS cryptococcosis and CNS tuberculosis have extremely poor prognoses unless diagnosed early. Immune reconstitution inflammatory syndrome shows distinct MRI findings from the offending opportunistic infections. Although distinguishing between HIV-related CNS diseases based on imaging alone is difficult, in this review, we discuss how pattern recognition approaches can contribute to their early differentiation.
