We present a fatal case of amoebic encephalitis due to spp. in an immunosuppressed male. Amoebic encephalitis can be a diagnostic challenge as clinical features are non-specific and imaging findings resemble other more common diagnoses such as tumours, haemorrhage or encephalitis from other causes. Here, we present the diagnostic imaging findings in this case and review the reported imaging findings in other cases throughout the literature.

Amoebas are characterized by their unique ability to exist both as free-living organisms and, occasionally, as parasites within host tissues, earning them the designation 'amphizoic amoebae'. While amoebic infections are less prevalent, their health impact can be tremendous, leading to several diseases. In low-income countries, poor sanitation and socioeconomic conditions significantly increase the risk of amoebic infections, particularly E.

Balamuthia amoebic encephalitis (BAE) is a rare, fatal parasitic infection of the central nervous system, with a current mortality rate above 95%. The high fatality rate is largely attributed to atypical clinicopathological features, delayed diagnosis, and the absence of effective treatment methods, so quick recognition of this disease is vital. In this paper, we present a survivor of BAE, who was confirmed through histologic examination and metagenomic next-generation sequencing (mNGS) of brain lesions.

Acanthamoeba castellanii is a widespread unicellular eukaryote found in diverse environments, including tap water, soil, and swimming pools. It is responsible for severe infections, such as Acanthamoeba keratitis and granulomatous amebic encephalitis, particularly in individuals with immunocompromisation. The ability of protozoans to form dormant and persistent cysts complicates treatment, as current therapies are ineffective against cyst stages and suffer from poor specificity and side effects.

Article Synopsis
- Acanthamoeba species are protozoa that can cause serious eye and CNS infections, and current treatments are often ineffective, especially in specific areas like the eye.
- The study evaluates the effectiveness of ethanolic fruit extract of E. umbellata, silver nanoparticles derived from it, and lauric acid in killing Acanthamoeba trophozoites and protecting DNA from damage.
- Results show that these treatments can significantly kill trophozoites and prevent DNA damage, suggesting potential new options for treating Acanthamoeba infections.

The free-living amoeba (NF) causes a rare but lethal parasitic meningoencephalitis (PAM) in humans. Currently, this disease lacks effective treatments and the specific molecular mechanisms that govern NF pathogenesis and host brain response remain unknown. To address some of these issues, we sought to explore naturally existing virulence diversity within environmental NF isolates.
