Focal pachymeningitis in a returning traveler: Don't forget melioidosis

Abstract

Background: Melioidosis is an endemic disease in South-East Asia and Northern Australia caused by a Gram-negative bacillus, Burkholderia pseudomallei. Manifestations are wide and neurological involvement have rarely been described.

Methods: In this paper, we report a patient returning from Asia with an unusual infection including CNS involvement consistent with a melioidosis.

Results: This diagnosis was challenging and complex to carry out with multiple considerations, mainly because of the atypical nature of the germ. Burkholderia pseudomallei can be easily misidentified with Burkholderia thailandensis (rarely pathogenic to humans) during bacterial culture because of their phylogenetic proximity. The main pitfall of the management was that the responsible infectious agent was not referenced in the MALDI-TOF (considered as a bioterrorism agent) and led to a wrong strategy.

Conclusions: This case of melioidosis shows the difficulty regarding the diagnosis of this disease in a patient returning from an endemic zone and its frequent multiple organs involvement. Melioidosis is an emerging, potentially fatal disease which requires prolonged antibiotic treatment. Difficulties in clinical microbiology laboratories diagnosis of melioidosis, especially in non-endemic areas where clinical suspicion is low, may delay treatment and affect disease outcomes.
