Acute encephalitis as initial presentation of leptospirosis.

Encephalitis is an acute inflammation of the brain matter, very often associated with viral infections, but it can also be caused by non-viral pathogens such as leptospirosis. Leptospirosis is a systemic disease caused by bacteria of the Leptospira genus. Leptospiral infection has a broad spectrum of clinical manifestations ranging from subclinical or mild illness to a fulminant life-threatening illness. In this case report we describe a young patient from Southern Albania with isolated encephalitis caused by Leptospira, where acute encephalitis was the initial presentation of the disease.
