Dubai: 68-year-old expat undergoes complex 9-hour brain surgery for rare tumour
A 68-year-old British expat in Dubai has successfully undergone a rare and complex nine-hour brain surgery to remove a life-threatening tumour that had invaded deep parts of his brain.
The patient, who wished to remain anonymous, was diagnosed with a 'butterfly glioma' — a rare and aggressive type of brain tumour that spreads across both hemispheres of the brain through the corpus callosum, the bundle of nerve fibres connecting the two sides.
His health concerns began in April 2025, when he noticed weakness in his right leg and had trouble standing up. He also struggled to swallow and experienced involuntary shaking in his left arm, symptoms that worsened over the following weeks. Eventually, he became unable to walk or lift his right arm.
Initially, doctors suspected a spinal issue after an X-ray and MRI showed signs of degeneration in his lower back. But as his symptoms progressed, further tests were done, and brain scans revealed a mass deep inside his brain.
He was referred to Dr Gopalakrishnan CV, a consultant neurosurgeon at Medcare Orthopaedics & Spine Hospital, who led the high-risk surgical procedure.
Using advanced neuronavigation technology, Dr Gopalakrishnan and his team accessed the tumour through a narrow passage in the frontal lobe. The tumour, located about three centimetres below the surface, was grayish and partly soft, but it had spread to critical areas including the right frontal lobe and the septum pellucidum, a delicate membrane near the brain's centre, which also had to be removed. Several damaged blood vessels and areas of dead tissue were also found.
The tests also revealed that his pupils were equal and reactive to light, with full and conjugate eye movements. According to the doctor, the cranial nerve examination was normal, although the fundus could not be assessed. Doctors found that the patient had some weakness in his right arm, particularly when bending and straightening the elbow and when lifting the arm sideways. "His leg was more affected, he had very limited strength in bending his right knee and moderate weakness when trying to straighten it," said Dr Gopalkrishnan, adding that his reflexes were normal, his sense of touch was mostly unaffected, and there were no unusual muscle twitches.
'Treating butterfly gliomas is one of the greatest challenges in neurosurgery,' said Dr Gopalakrishnan. 'These tumours grow aggressively in deep parts of the brain and can change a person's personality and behaviour. Our aim is not just to extend life, but to preserve its quality. With precise surgery and cutting-edge treatments like Tumor Treating Fields and proton beam therapy, we're pushing the boundaries of what's possible.'
Butterfly gliomas, or glioblastomas, are among the most aggressive brain tumours. They can cause severe symptoms like headaches, personality changes, seizures, and memory or movement problems. Standard treatment usually involves surgery, followed by radiation and chemotherapy.
The average survival time after diagnosis is around 10 to 15 months, but outcomes depend on age, overall health, how much of the tumour can be removed, and certain genetic markers. New approaches such as immunotherapy and targeted treatments are offering fresh hope.
Reflecting on his journey, the patient shared that getting this diagnosis was overwhelming at first. 'But I have found strength I didn't know I had. With the care and encouragement from my medical team and loved ones, I am staying hopeful and focusing on living each day with purpose and gratitude.'
