Contouring
Meningioma

Summary:

This advanced session, led by Dr. Muthukkumaran Thiagarajan, Clinical Oncologist at Hospital Kuala Lumpur, delivers an in-depth exploration of the radiotherapy contouring process for meningiomas. It covers the clinical, radiological, and pathological features of meningiomas, differences between low-grade and high-grade disease, and the rationale for various treatment approaches, including surgery, fractionated radiotherapy, stereotactic radiosurgery (SRS), and stereotactic radiotherapy (SRT). Participants will gain clarity on target volume delineation, the role of MRI and CT fusion, organ-at-risk constraints, and decision-making nuances in complex cases such as skull base tumours, optic nerve involvement, and postoperative residual disease. Practical case examples reinforce learning, with emphasis on guideline-based contouring, image fusion accuracy, and avoiding overtreatment. By the end of this session, attendees will be able to apply evidence-based contouring strategies for meningiomas in daily clinical practice.
