Introduction: Crossed anarthria cases are uncommon and rather old.
Observation: We report the case of a right-handed 55-year-old man who presented crossed pure anarthria due to a hemorrhage in the premotor cortex (feet of F1 and F2) and in the high part of Pierre-Marie's quadrangle.
Conclusion: The study of different tasks (articulation, verbal fluency, direct object word-generation from a verb) showed a dissociated lateralisation of his language. Lexico-semantic and grammatical tasks are processed in the left hemisphere. Articulation programming occurs in the right hemisphere.
