Özet
Achieving gross total resection is the primary prognostic factor in pilocytic astrocytomas. The spherical coordinate system (SCS) is an alternative to the Cartesian system for defining a point’s location in space. While the Cartesian system uses X, Y, and Z axes, the SCS utilizes ? (distance from the origin), ? (the angle with the positive X-axis, 0 to 360 degrees), and ? (the angle with the positive Z-axis, 0 to 180 degrees). A 73-year-old female patient presented with headaches, dizziness, and gait disturbance over the past month, along with nausea and vomiting. She had previously undergone cerebellar tumor surgery in February 2020, and two years later, similar solid and cystic structures reappeared, suggesting a residual tumor. In such cases, using the SCS may help reduce remnant tumor rates and minimize the need for secondary operations.
