Malignant pleural mesothelioma (MPM) is an aggressive malignant neoplasm that was thought to be a localised disease with limited metastatic capability. However, recent post-mortem studies have identified metastases to the central nervous system (CNS) in about 3% of cases.

Case Description

We present the case of a 65-year-old with a solitary supratentorial metastatic deposit of MPM treated with surgical resection and adjuvant whole brain radiotherapy. Despite a good surgical outcome with symptomatic recovery, the patient died of cardiopulmonary compromise five months postoperatively.


Although rare, CNS metastasis of MPM is a condition that neurosurgeons should be aware of. CNS metastases may occur via three distinct mechanisms, namely perineural spread, leptomeningeal carcinomatosis and, most commonly, haematogenous spread leading to parenchymal deposits. Surgical resection of these deposits can lead to symptomatic improvement, and together with radiotherapy, to local disease control. However, the overall survival remains poor.
