Necrose primária do corpo caloso (doença de marchiafava-bignami) relato de cinco casos

São relatados 5 casos de doença de Marchiafava-Bignami, estudados em seus aspectos anátomo-patológicos, de correlação clínica e de etiopatogenia. O aspecto anátomo-patológico, de desmielinização na parte central do corpo caloso, comprometendo também outras comissuras, é característico da doença. Os autores chamam a atenção para o papel do alcoolismo e da desnutrição na patogênese da lesão e para a predominância, nesta série, de casos do sexo feminino, ocorrência rara entre os casos descritos na literatura

Aseptic meningitis after intrathecal baclofen injection.

International audienceStUDY DESIGN: Two case reports of aseptic meningitis after intrathecal baclofen injection. OBJECTIVES: To report an unusual complication of intrathecal baclofen injection during test injections. SETTING: Department of Neurological Rehabilitation, R Poincar??al (Paris-Ile de France-Ouest University). CASE REPORTS: We present two cases of chemical meningitis after intrathecal baclofen injections by lumbar puncture. These cases presented with febrile meningeal syndromes during the 24 h following intrathecal baclofen injection. Direct cerebrospinal fluid (CSF) examination and CSF cultures were negative. An intense cellular reaction was observed with a marked predominance of neutrophils. Meningitis resolved spontaneously over 3-4 days. CONCLUSIONS: Chemical meningitis is a rare complication of intrathecal baclofen injections that must be recognized. It is a diagnosis of exclusion and its pathophysiological mechanism remains unclear
