HISTORY OF PRESENT ILLNESSHISTORY OF PRESENT ILLNESS
• Oct 2004: Transient visual loss OU – lasting 2-3 seconds followed by 5 seconds of whitening vision and blurred vision OD
• Over next few months noticed a progressive decline in vision OD
• Jan 2005: Saw a local ophthalmologist- remembers being told that “something was pale”. Brain MRI normal.
• April 2005: Transient visual loss OU – lasting 2-3 seconds, followed by several seconds of “whitening” and “fuzzy vision”. Eye pain OD for 5 minutes
• April 2005: Saw a local ophthalmologist Hand motions OD and 20/70 OS Bilateral optic nerve atrophy

•Primitive appearing epithelial cells in a loose, variably cellular, myxoid matrix resembling extraembryonic mesoblast
•Eosinophilic hyaline globules immunoreactive to αFP
•Epithelial elements proliferate in sheets with intervening meshwork of irregular tissue spaces
•Schiller-Duval bodies: papillae formation
•Brightly eosinophilic, PAS-positive and diastase resistant hyaline globules (inconsistent finding but diagnostic)
•Variable mitotic activity, necrosis uncommon
•Cytoplasmic immunoreactivity for αFP is characteristic
• Local radiation therapy (RT) that includes the suprasellar region, pineal gland and periventricular areas.
• Craniospinal irradiation (CSI) reserved for patients with evidence of leptomeningeal disease, multiple tumors or simultaneous pineal and suprasellar involvement.
• Greater success with protocols that use chemotherapy (cisplatin) followed by RT (event free survival rate ~92%), although no randomized trial completed.
• Chemotherapy appears to be essential for successful treatment ofintracranial NGGCTs
• Platinum-based chemotherapy (i.e., carboplatin + etoposide + bleomycin) have shown moderate effectiveness, with complete and partial response rates ~80%
• Long-term surrival rates (>50%) with combined platinum containing chemotherapy and RT.
• High incidence of leptomeningeal metastasis, hence CSI is usually recommended.
• Surgical resection for patient with residual radiographic abnormalities and normalized tumor markers following chemotherapy, because of possibility of residual teratoma.
