title: Neurosarcoidosis--a diagnostic pitfall with consequences.
abstract: Neurosarcoidosis is often a diagnostic dilemma, especially in the absence of other organ involvement. We report a 64-year-old patient who had suffered from paraplegia due to an intramedullar process since 1995. The presumptive diagnosis based on computed tomography was spinal cord infarction. Six years later, he complained about increasing paresthesia. Magnetic resonance imaging of the spinal cord showed nodular meningeal enhancement. Computed tomography of the thorax revealed mediastinal and hilar lymphadenopathy. Bronchoscopy under generalized anesthesia was performed. The differential cell count in bronchoalveolar lavage fluid showed 39% lymphocytes and a CD4(+)/CD8(+) ratio of 17.7. Histological examination of biopsy specimens from the hilar lymph nodes revealed non-necrotizing granulomas with epitheloid cells and Langerhans-type giant cells, consistent with the diagnosis of sarcoidosis. As a result of these findings, lumbar puncture was undertaken and a raised protein concentration and pleocytosis were found in the cerebrospinal fluid. The number of lymphocytes (9,250 lymphocytes/l) and a CD4(+)/CD8(+) ratio of 10.78 led to the diagnosis of neurosarcoidosis. Paralysis might have been prevented if the correct diagnosis of neurosarcoidosis had been established earlier in this patient.
