Primitive neuroectodermal tumors (PNETs) are highly malignant neoplasms of embryonal origin manifesting in children and adolescents, rarely seen in adults. Carcinoma lung with hemorrhagic metastasis to the brain is very common, but primary lung PNET with hemorrhagic brain metastasis is extremely uncommon. We hereby report a 29-year-old female diagnosed as PNET lung was treated with vincristine, adriamycin, and cyclophosphamide alternating with ifosfamide plus etoposide followed by radiotherapy (RT). After 9 months, she developed hemorrhagic brain metastasis from PNET lung confirmed from tissue immunohistology postcraniotomy. Received palliative whole brain RT followed by oral pazopanib resulting in significant improvement in performance status. A thorough review of literature reveals that our case may be the second case of primary lung PNET with hemorrhagic brain metastasis and also the first to be exhibited oral pazopanib resulting in a significant therapeutic effect to be reported in world literature till date.
