Abstract

A retrospective analisis of six cases of central nervous system paracoccidioidomycosis, all but one proven by biopsy and surgery, was carried out to study the CT and clinical data and pathological correlation. Most of the patients were from the country. Headache, vomiting, seizures and hemiparesis were the most frequent symptoms. Papilloedema was present in four patients with raised intracranial pressure. Five patients had chronic lung disease and two with advanced systemic disease, skin and mucous membrane lesions were also observed. The neurological disturbance was sometimes the presenting features and the diagnosis was discovered incidentally after surgery. Both solitary and multiple parenchymal lesions were observed and the cerebral hemispheres were more commonly involved in four patients. Local meningeal involvement was observed in one with a single cortical granuloma. We enphasise the usefulness of CT, showing a rounded or lobulated mass with an isodense or radiolucent centre after contrast enhancement, surrounded by an irregular wall of varying thickness. There was always moderate oedema, extending peripherally. Other infections or neoplastic diseases may present similar findings. Preoperative diagnosis should rest on integration of clinical data, chest films, laboratory and neuroimaging studies.
