CLIPPERS (Chronic Lymphocytic Inflammation with Perivascular Pontine Enhancement and Steroid Response) is a recently described neuroinflammatory disorder in which symptoms involving the brainstem predominate, with variable pattern on neuroimaging and a perivascular infiltrate of T lymphocytes on brain biopsy. We present a case of a 50-year-old male who presented symptoms of asthenia, adynamia, weakness in lower limbs extremities, sphincter disorder and ataxia. Patient was extensively studied to rule out infectious, neoplastic, autoimmune, and demyelinating conditions. Diagnosis was made taking into account significant clinical-imaging elements, remarking the spinal cord involvement in this patient. Treatment with steroids and steroid-sparing agents, such as methotrexate, was found to be effective. Very few cases in the literature to date describe CLIPPERS-associated spinal cord involvement.

Síndrome de Weber, Etiología Infrecuente y Resolución Espontánea
Weber’s syndrome is characterized by a third nerve palsy associated with contralateral hemiparesis because of a damage to the cerebral peduncle, due to multiple etiologies.
We report the case of a 40 years old man with no history of diabetes mellitus or hypertension who suddenly presented with diplopia and left hemiparesis. The MRI scan showed an angioma in the midbrain. Its relevance lies in the rare etiology of this syndrome and its spontaneous resolution.
