Intracranial metastases in small cell carcinoma of the lung: correlation of clinical and autopsy findings
Research output: Contribution to journal › Journal article › Research › peer-review
Two hundred-twelve consecutive patients with small cell carcinoma of the lung were included in an evaluation of clinical and diagnostic neurologic findings of intracranial metastases. A correlation of premortem findings to postmortem examination of the brain was obtained in 87 of the patients. Clinical intracranial metastases were diagnosed in 21.2% on the basis of symptoms and signs. At autopsy 44 of the 87 patients (50%) had metastases. Lesions located to the posterior cranial fossa were demonstrated in 53% of the positive autopsies. A correlation of 96% existed between significant premortem clinical findings and positive autopsy, while 33% had clinically "silent" metastases at autopsy. A neuro-oncologic examination was performed in 49 patients at the time of presentation of neurologic symptoms. Twenty-eight patients were considered to have intracranial metastases. Gait disturbances were the presenting signs in more than 50% of the patients. Brain metastases were demonstrated at autopsy in 14 of 15 patients considered to have intracranial metastases by the neuro-oncologist, and clinically "silent" metastases were observed in one out of 10 patients. Radionuclide brain scan was negative in seven of 13 patients in spite of "positive" neuro-oncological examination had a subsequent positive autopsy. Cerebrospinal fluid examination was of no value in the diagnosis of brain metastases. It is concluded that a careful clinical examination by a neuro-oncologist is of great value in early detection of brain metastases, especially in diagnosing metastases to the posterior cranial fossa.
