Cerebrospinal Fluid Titer of Chorionic Gonadotropin in Patients with Intracranial Metastatic Choriocarcinoma

Abstract

Two patients with markedly elevated titers of chorionic gonadotropin in the cerebrospinal fluid attributable to brain metastases from a choriocarcinoma are presented. It is suggested that serial titration of the cerebrospinal fluid for chorionic gonadotropin may be useful in diagnosing intracranial metastases in patients with choriocarcinoma.
