title: Multiple deep-seated cavernomas in the third ventricle, hypothalamus and thalamus.
abstract: BACKGROUND
  Cavernomas are rarely located in the third ventricle, hypothalamus, or thalamus. In this report, we present our experience managing a patient with three cavernomas, one each in the floor of the third ventricle, hypothalamus, and left thalamus.
  
  
  METHODS
  This 62-year-old woman had had an unsteady gait and weakness of both legs for six months. Magnetic resonance imaging (MRI) revealed multiple intracranial tumours in the third ventricle, hypothalamus, and left thalamus. The third ventricle tumour was found to be a cavernoma by intra-operative endoscopic examination and then was excised via a transcortical, transventricular approach. Pathology revealed a cavernoma. The other two tumours were assumed to be cavernomas because of their MRI features. Three days after surgery, the patient developed right hemiparesis and disturbance of consciousness. Computed tomography revealed a left thalamic haemorrhage. After conservative treatment, her conscious level gradually recovered and she could walk with support seven months after surgery.
  
  
  CONCLUSIONS
  Our experience with this rare case of multiple, deep-seated cavernomas suggests that management of such patients requires specific consideration of the clinical manifestations, location, size, and previous bleeding history.
