Answer

Answer

Chest and abdominal CT scans should be performed, because a small minority of immunocompetent patients has an extraneural source for their cerebral lymphoma. Common sites are abdomen and breast. Therefore, after the establishment of a definitive diagnosis of PCNSL, these staging procedures should be performed. Staging of extent of extraneural lymphoma has a higher yield in patients with AIDS.
