title: Supratentorial, extraventricular choroid plexus carcinoma in an adult: case report.
abstract: OBJECTIVE
  Choroid plexus carcinoma (CPCa) is an uncommon tumor rarely occurring in patients older than 2 years of age. The case reported herein represents the first documented example of a primary supratentorial, extraventricular CPCa in an adult. The scant literature regarding this topic is reviewed.
  
  
  METHODS
  A 68-year-old woman presented with transient expressive aphasia. Magnetic resonance imaging demonstrated an avidly enhancing, left temporal, extra-axial mass with associated parenchymal cysts.
  
  
  METHODS
  The tumor was gross-totally removed via a frontotemporal craniotomy. A diagnosis of CPCa was made on histological, immunohistochemical, and ultrastructural grounds. Postoperatively, the patient was treated by local radiotherapy and temozolomide. A magnetic resonance imaging scan 44 months after surgery showed no evidence of residual or recurrent tumor.
  
  
  CONCLUSIONS
  CPCa infrequently affects adults. Only rarely does it present as a supratentorial, extraventricular mass. Resection is the mainstay of therapy. Adjuvant radiation and chemotherapy are rational treatment options.
