The Facts

Patient consults GP and neurosurgeon after developing headaches

The patient was a 73-year-old man who was happy, fit and active. In early 2011, he began to experience headaches and consulted his GP for treatment.

After performing various diagnostic investigations which were found to be inconclusive, the man's GP referred him to a neurosurgeon.

The man consulted the neurosurgeon, who identified on a CT scan that the man had a brain tumour. The surgeon took the view that the tumour could be removed endoscopically, without the need to open up the patient's skull. The surgeon said that this surgery would enable him to remove the tumour through the patient's nose.
