Abstract

We report a patient in Japan infected with Cryptococcus gattii genotype VGIIa who had no recent history of travel to disease-endemic areas. This strain was identical to the Vancouver Island outbreak strain R265. Our results suggest that this virulent strain has spread to regions outside North America.

Highlights

  • Cryptococcus neoformans and C. gattii are closely related species of yeast; C. gattii was previously classified as C. neoformans var. gattii [1]

  • These strains have spread to mainland British Columbia and the Pacific Northwest region of the United States [1,4,5]

  • We report a case of cerebral cryptococcoma caused by C. gattii VGIIa in a patient from Japan who had no recent travel history to known diseaseendemic areas

Summary

Introduction

Cryptococcus neoformans and C. gattii are closely related species of yeast; C. gattii was previously classified as C. neoformans var. gattii [1]. We report a case of cerebral cryptococcoma caused by C. gattii VGIIa (a strain identical to the Vancouver Island outbreak major genotype strain R265) in a patient from Japan who had no recent travel history to known diseaseendemic areas. The Patient In 2007, a 44-year-old man (sign painter) from Japan who was not infected with HIV came to the University of Tokyo Hospital with a 2-month history of headache and loss of right-sided vision in both eyes (right homonymous hemianopsia).
