ASTRO E-contouring for CNS webinar

Faculty:
Dr. Elham Rahimy, MD

Case Description:
64yo M, KPS 60, GBM (IDH WT) of the left temporal lobe with asymptomatic transient leptomeningeal (LM) enhancement, MGMT negative. 

• Presented with symptomatic hydrocephalus (acute AMS, vomiting), found to have hemorrhagic tumor and leptomeningeal enhancement of the posterior fossa and upper C-spine.
• Underwent VP shunt with improvement of hydrocephalus symptoms, and biopsy alone of the tumor.
• LM enhancement resolved on interim MRI 5 weeks later (LM enhancement felt to be secondary to tumor hemorrhage).
• After multidisciplinary evaluation and discussion, planned for hypofractionated radiotherapy with concurrent/adjuvant temodar.
• Images fused: Initial MRI (T1+C and T2; MR secondary 1 and 2) showing the extensive LM enhancement in the posterior fossa, and ~5 week follow up MRI day before simulation with resolution of LM enhancement (T1+C and T2; MR secondary 3 and 4). He was claustrophobic with some motion degradation on scans despite Ativan.
 
Homework:
• GTV on Slices 58, 59, 60, 61
• CTV on Slices 58, 59, 60, 61
