Introduction:
Paraneoplastic limbic encephalitis is a rare disease, usually associated with small cell lung cancer.
Case Report:
We report in this publication the cases with different age brackets, who presented with various neurological symptoms such as repetitive seizures or anterograde amnesia. Cerebral CT-scan, cerebral MRI and anti onco-neural paraneoplastic antibodies were suggesting the diagnosis of paraneoplastic limbic encephalitis. Etiological exploration lead to the diagnosis of locally advanced small cell carcinoma of the lung. We started rapidly a curative protocol associating chemotherapy and sequential thoracic radiotherapy.
Conclusions:
we insist on the diversity of the imaging findings, immunological analyses and outcome on treatment of this entity. Prognostic impact remains also unclear.

Basic Characteristics of Cells
A living cell has a plasma membrane, a bilayer of lipids that separates the aqueous solution inside the cell called the cytoplasm from the outside environment.
