Primary intracranial squamous cell carcinoma--case report

A 50-year-old female presented with primary intracranial squamous cell carcinoma (SCC) at the right cerebellopontine angle manifesting as right facial nerve paresis. She had undergone gross total removal of a right cerebellopontine angle epidermoid cyst 10 years before and had done well until recently. Magnetic resonance imaging showed a heterogeneous tumor with markedly enhanced irregular margin. Subtotal removal of the tumor was achieved. Histological examination showed moderately differentiated SCC. After surgery, she underwent chemotherapy and gamma radiosurgery. She is now well 5 years after the diagnosis of SCC.
