In 1991, a 62 year old woman, was admitted for the first time to the neurosurgical unit of Hospital das Nações in Curitiba, Brazil, with a 20 year history of gait disorders and dizziness. A CT scan showed a temporal lobe homogeneous lesion which was subsequently partially resected. Histopathological examination diagnosed a meningothelial meningioma. Seven years later, in 1998, she presented again with the same clinical manifestations, and was submitted to radiotherapy. Due to the absence of clinical and radiological remission, another surgical resection was performed, and the pathological diagnosis of meningothelial meningioma was once more confirmed. Six months later, at age 70, her symptoms recurred. Magnetic resonance imaging (MRI) studies revealed the initial lesion associated with a new tumour in the frontal parasagittal region in the left side. The patient underwent a new surgical procedure, with partial resection of the tumoral mass.
