A very rare inflammatory disease of CNS, CLIPPERS syndrome, was recently described and only a few sporadic cases are reported in the medical literature. Its etiology and pathogenesis are unknown, that together with the polymorphic and sometimes confounding neurological manifestations, and radiological findings represent a real diagnostic and therapeutic challenge for clinicians. Aim: To highlight the importance of clear and specific diagnostic assessment. Here we present the case of a 40-year-old male with a subacute lymphocytic midbrain inflammation accompanied by vasculitis. We discuss the symptoms, imaging and treatment of this lesion.
