Marina A. Kastelan is a neurosurgeon who works at North Shore Private Hospital in Sydney, NSW. She helps look after people with brain tumours, especially when scans show something more complex. In many cases, this kind of diagnosis can feel scary and hard to take in, so the aim is to keep things clear and steady from the start.
Her clinical work focuses on conditions such as astrocytoma and glioma, including glioblastoma. She also treats other brain tumour types like ependymoma, oligodendroglioma, and gliosarcoma. At times, patients are dealing with things like necrosis or gliomatosis cerebri, where the tumour can affect more than one area. Each case is different, and she looks at the bigger picture rather than only one scan result.
As a neurosurgeon, her role is usually about making sure the right surgical plan is chosen and done safely. Brain tumour surgery can be complicated, and the details matter. Over time, she works with patients and their families to understand what the procedure is for, what recovery may look like, and what other treatment steps might be part of the care plan. That matters for both short-term decisions and longer-term follow-up.
Marina also keeps up with the changes in how brain tumours are treated. Treatments can move forward as new knowledge comes in, and teams often adjust plans based on the latest evidence and each person’s situation. If you’re facing a brain tumour diagnosis, it helps to have care that’s grounded, practical, and focused on the individual, not just the label on a report.
She is based in the North Shore Private Hospital area, so patients in Sydney and nearby suburbs can access specialist neurosurgical care without needing to travel far. If ongoing monitoring, review appointments, or next-step discussions are needed, she stays involved as part of the wider care process.
