We present a case of a 27-year-old female with obstructive hydrocephalus due to aqueductal stenosis. On August in 1988, she was treated for germinoma with surgical partial resection and radiation (whole cranial 50 Gy). She was cured and had no tumor recurrence. On February in 2003, her activity of daily life was decreased, and CT and MRI disclosed segmental occlusion or severe stenosis of aqueduct with hydrocephalus. Endoscopic third ventriculostomy was performed on March in 2003. After surgery, her activity of daily life improved. In operative view by neuroendoscope, an old bleeding point at the aqueduct neighbor was discovered, and a blood clot was obstructing the flow of cerebrospinal fluid.
