RADIOLOGICAL EVIDENCE OF LYMPHATIC DRAINAGE OF BONE MARROW CAVITY IN LONG BONES

Abstract

Injection of Lipiodol UF into the distal epiphyses of
tibia and femur in the dog was followed within several
minutes by visualization of lymphatics draining the
bone. Some of the radioopaque material was retained
in the bone marrow cavity and tiny lymph vessels
originating in that area could be seen. Contrast
medium filled also the popliteal lymph node. The
problem of migration of bone marrow lymphocytes
through the lymphatics to the regional lymph nodes
is discussed.
