MRI:
The 47-year-old male patient presented with a right thalamic pilocytic astrocytoma. The tumor was completely resected via a transventricular approach. One month after the operation the patient was admitted with an increasingly serious gait disorder, headaches and fine motor disturbances. The MR imaging showed a huge increase in the size of the right temporal and occipital horn and the dorsal areas of the cella media.
Navigation:
In order to determine the ideal entrance point and for intraoperative orientation, the operation was performed under neuronavigational guidance.
