ASTRO eContouringWebinar: GBM patients with leptomeningeal disease

Workshop:
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.
