Solitary cerebellar metastasis of malignant pleural mesothelioma: case report.

Abstrait
BACKGROUND
Malignant pleural mesothelioma is an uncommon malignancy that rarely metastasizes to the central nervous system and even less frequently occurs as a solitary lesion.
METHODS
We present a 71-year-old white female, nonsmoker, with no occupational exposure to asbestos. She presented with a 15-lb. weight loss over several months and persistent right subscapular pain radiating to her anterior chest. Imaging studies revealed a pleural mass, and biopsy confirmed fibrous type malignant pleural mesothelioma. During a metastatic workup, computed tomography (CT) and magnetic resonance imaging (MRI) of the head demonstrated a 1 cm subcortical, contrast-enhancing lesion without surrounding edema in the right posterior cerebellum. Surgical resection of the solitary cerebellar mass revealed fibrous-type metastatic malignant mesothelioma. Postoperatively, the patient received a combined chemotherapy regimen of Adriamycin and Cisplatin and underwent whole brain radiation therapy.
CONCLUSIONS
We report the first resection of a solitary cerebellar metastasis of malignant pleural mesothelioma. We also review past cases of intracranial metastasis of this malignancy, its histologic subtypes, outcome, and recent treatment modalities.
