Histological lesions with intralesional Halicephalobus gingivalis. a. In the renal parenchyma, intralesional nematodes displayed a smooth cuticle and in transversally sectioned parasites a rhabditic esophagus was noted. H&E, bar 20 μm. b. The dense white tissue of the right kidney was composed of a severe granulomatous nephritis with numerous intralesional rhabditic nematodes. H&E, bar 20 μm. c. Intravascular larvae were noted in the cerebral parenchyma with mild lymphocytic to eosinophilic encephalitis. H&E, bar 20 μm. d. The leptomeninges of the cerebellum was moderately to severely expanded by eosinophils, and mononuclear cells including giant cells. Scattered throughout the tissue, and partly digested in the cytoplasm of giant cells, were nematode larvae. H&E, bar 20 μm
