Questions 4 and 5 are based on the following clinical scenario:
A 57-year-old man presents with neck swelling, night sweats, and fatigue. On further evaluation he is found to have diffuse lymphadenopathy, splenomegaly, and lymphocytosis. He undergoes an excisional lymph node biopsy which shows mantle cell lymphoma (MCL). Staging evaluation reveals extensive adenopathy above and below the diaphragm (with some sites in the 5 to 10 cm range), splenomegaly, bone marrow involvement, and a moderately elevated LDH.
Which of the following diagnostic procedures is also likely to reveal MCL?
