Interhemispheric cyst causing leg monoparesis in the elderly--case report.
A 64-year-old female presented with a rare case of interhemispheric cerebral cyst manifesting as progressive monoparesis in the right lower extremity for 2 years. Surgical excision of the cyst wall was performed and communication to the subdural space was created. Postoperatively, the cyst was greatly reduced in size, and the neurological signs and symptoms were markedly improved. Interhemispheric cyst often presents with motor disturbances such as hemisparesis or paraparesis. These symptoms tend to progress slowly and sometimes years are required for a proper diagnosis. Interhemispheric cyst can also cause slowly progressive monoparesis in the lower extremity.
