ABSTRACT
A rare cause of cerebral hemorrhage is the metastasis of choriocarcinoma from gynecology. Herein, we report a case of a patient with brain metastasis of choriocarcinoma with cerebral hemorrhage. A 14-year-old female who had undergone surgery for a hydatidiform molar pregnancy presented with a disturbance of consciousness due to cerebral hemorrhage. Imaging studies revealed the presence of a cerebral aneurysm and several mass lesions in the lung field, and high serum beta-human chorionic gonadotropin level was confirmed. Thus, we suspected cerebral hemorrhage caused by brain metastasis of choriocarcinoma. She went into a coma, and an emergency craniotomy was performed to remove the hematoma and aneurysm. The pathology of the aneurysm was pseudoaneurysm due to the rupture of the vascular wall caused by increasing metastatic cells from choriocarcinoma in the cerebrovascular wall. Therefore, multidrug chemotherapy was immediately initiated. The choriocarcinoma, including the metastatic lesions, is in remission. To improve the outcome of choriocarcinoma, it must be diagnosed early, and treatment should be immediately started. Moreover, neurosurgeons should be aware of such diseases and consider them as one of the differential diagnoses, particularly in females of reproductive age with cerebral hemorrhage.
ABSTRACT
We herein report a 46-year-old man presenting with locked-in syndrome secondary to meningovascular syphilis. Brain magnetic resonance imaging (MRI) demonstrated multiple acute infarctions in the left ventromedial pons, right basis pontis, and left basal ganglia. His locked-in syndrome was hypothesized to have been caused by thrombosis of the small paramedian branches of the basilar artery due to syphilitic arteritis. This is a unique case of bilateral ventromedial pontine infarction caused by meningovascular syphilis that presented as locked-in syndrome. Meningovascular syphilis should be included in the differential diagnosis of uncommon stroke, particularly in young men.
