[Bartonella hensalae encephalopathy].

INTRODUCTION

Bartonella hensalae is a poorly known cause of encephalopathy in young subjects.

OBSERVATION

A 17 year-old adolescent was admitted in a state of emergency because of frequent convulsive seizures and inter-critical drowsiness. The diagnosis of encephalopathy was made on the association of these clinical signs and electro-encephalographic abnormalities. The presence of a cat in his home, a right axillary lymph node that had appeared in a context of fever, and positive serological kinetics related this encephalopathy to a bartonellosis. The course was good.

DISCUSSION

Diagnosis of a Bartonella hensalae encephalopathy is based on a range of anamnesic, clinical and microbiological arguments. The potential interest of antibiotic therapy and its modalities remains to be established.
