An unusual presentation of intracranial metastasis

Solitary intraventricular metastasis is an extremely rare entity with poor outcome following surgery. A 26 years old male presented with features of raised intracranial pressure. An extensive intraventricular tumor was diagnosed as septal glioma on imaging. A gross total microsurgical excision of a vascular infiltrative tumour with subependymal infiltration resulted into marked pneumocephalus and progressive oedema of white matter. The patient died on 4th postoperative day the biopsy of tumor specimen revealed a metastatic papillary adenocarcioma. Venous infarct was thought to be the cause of an extensive white matter infarct. Literature is reviewed to explore the primary sites, clinical manifestations and causes of mortality in these cases.
