Intracranial Cystic Metastasis Mimicking Neurocysticercosis in a Pregnant Woman

Brain metastasis can form large cystic lesions, and its differentiation on the basis of imaging findings alone is difficult. A 36-year-old woman with headache visited emergency room. Two years ago, she was diagnosed as neurocysticercosis and had taken anti-parasite medications. However, in the current visit, the sizes of intracranial cystic lesions increased. Brain biopsy reported metastatic neuroendocrine tumor, and chest CT showed the primary site of the tumor. Cystic brain metastasis should be considered in cases with cystic brain lesions.

Distal Subclavian Artery Occlusion Causing Multiple Cerebral Infarcts Consequence of Retrograde Flow of a Thrombus?

Intracranial embolization usually arises from the heart, a vertebrobasilar artery, a carotid artery, or the aorta, but rarely from the distal subclavian artery upstream of an embolus. We report on a patient who experienced left shoulder and forearm pain with weak blood pressure and pulse followed by concurrent onset of left hemiplegia. This case is a rare example of multiple cerebral embolic infarctions, which developed as a complication of distal subclavian artery thrombosis possibly associated with protein S deficiency.
