[Pulmonary nocardiosis complicated with multiple cerebellar abscess].

A 56-year-old man with diabetes mellitus and alcoholic liver cirrhosis was admitted on an emergency basis to our hospital for further examination of headache, general fatigue and dysarthria. He had been treated with antifungal drugs on the suspicion of pulmonary mycosis. Brain MRI revealed multiple cerebellar abscesses with ring enhancement. Due to depression of mental status despite medical treatment, he underwent suboccipital craniotomy and enucleation of the cerebellar abscess, resulting in marked improvement of consciousness level. As the culture of his abscess content yielded Nocardia farcinica, the definite diagnosis of Nocardial cerebellar abscesses and pulmonary Nocardiosis were made. Pulmonary Nocardiosis improved by oral co-trimoxazole treatment. Moreover, no recurrence of cerebellar abscesses was evident. This case indicates that the possibility of Nocardial infection should be considered in the immuno-compromised hosts.
