Mild Encephalitis with a Reversible Splenial Lesion: A Clinical Benign Condition, often Underrecognized - Clinical Case and Literature Review.

Mild encephalitis with reversible lesion in the splenium is a clinicoradiological syndrome characterized by a variegated symptomatology with a solitary mass in the central portion of the splenium of the corpus callosum. Complete spontaneous resolution is the hallmark of this syndrome, though its pathogenesis is still unknown. We describe the clinical picture of a 51-year-old woman who developed a partial sensitive seizure, with MRI evidence of a lesion localized in the posterior portion of the corpus callosum.

Isolated polio-like syndrome after tick-borne encephalitis presenting with acute hyperckemia.

Tick borne encephalitis virus infection usually shows a biphasic course. In the first stage of illness symptoms are similar to a flu-like syndrome, then after a defervescence period, fever may represent with neurological manifestations ranging from mild meningitis to severe encephalomyelitis. We report the clinical case of an adult man presented with an acute proximal hyposthenia, severe hyperckemia, clinical and laboratoristic evidence of acute tick borne virus infection.
