Two different primary tumours of the brain in a patient with breast cancer.

Some reports on multiple primary brain tumours have been published. When one or more tumours are found in brain scintigraphy they are often supposed to be metastases. Further investigations may thus be given up, especially if the patient has or has had a malignant tumour in some other part of the body. In this report a case is described where the patient began to have cerebral symptoms two years after she had been operated for breast cancer. In the scintigraphy a tumour was found in both brain hemispheres. The tumours were regarded as metastases. But when the patient died in a geriatric hospital it was recognized from the autopsy that one tumour was a meningioma and the other a glioblastoma multiforme.
