Granulomatous amebic encephalitis (GAE), or meningoencephalitis due to Acanthamoeba spp. and leptomyxid ameba are uncommon CNS infections that generally occur in immunocompromised hosts. We describe a case of GAE caused by Balamuthia mandrillaris previously designated as a leptomyxid ameba, in an apparently healthy 14-year-old Venezuelan boy. This case was(More)
A sural nerve dissected from a recently dead patient displayed an unusual X-ray diffraction pattern, suggesting that in situ and at the time of the patient's death the myelin sheaths were in a swollen state. Diffraction patterns of the swollen type were also recorded from: (1) a sural nerve from the corpse of a neurologically healthy person after soaking(More)
Adult polyglucosan body disease is a recently established clinicopathological entity, with few cases reported in the literature. In this paper we describe a case of a 46-year-old man who had died to a pancreatic cancer whose neuropathological study revealed a massive accumulation of polyglucosan bodies in the cerebral white matter, brainstem, cerebellum and(More)

In the central nervous system (CNS) of HIV(+) patients, parasitic protozoans like Toxoplasma gondii have been described as responsible for the space occupying lesions (SOL) developed. However, the involvement of Trypanosoma cruzi is also(More)
