Lymphographic appearance of benign conditions simulating lymphoma

Imaging of Spinal Manifestations of Hematological Disorders

Imaging manifestations of hematological diseases and their potential complications are broad, and there may be significant overlap in features of various disease processes. Knowledge of appropriate choice of imaging test, pertinent imaging patterns, and pathophysiology of disease can help the reader increase specificity in the diagnosis and treatment of the patient. Most importantly, we encourage readers of this review to engage their radiologists during the diagnostic, treatment, and management phases of care delivery.

Relation between extension of non-Hodgkin's lymphoma and lymphographic findings

The relationship between the degree of lymph node foaminess observed in bipedal lymphadenograms and absolute peripheral lymphocyte counts in non-Hodgkin's lymphoma was analyzed with regard to the initial location, clinical stage, histologic subtype, and bulkiness of the disease. In the nodal type of disease with supra-diaphragmatic presentation, an inverse relation was often found between the peripheral lymphocyte count and the foaminess score. However, if the disease originated in the infra-diaphragmatic regions no such relation was found. The implications of these observations are discussed.

False positive lymphography in Hodgkin's disease: a histologic-lymphadenographic correlation

A series of 99 consecutive patients having a staging laparotomy for Hodgkin's disease was reviewed. Negative lymph nodes removed during the laparotomy were correlated with lymphograms reported as positive or suspicious. Four patients had large nodes with a prominent hilar area or irregular cortical fat deposits. In two other patients a cluster of small lymph nodes accounted for the radiologic misinterpretation.

Lymphographic demonstration of cyclic changes in lymph node size during Pel-Epstein fever

Pel-Epstein fever cycles, consisting of 1-2 weeks of high fever separated by afebrile periods of the same duration, are classically characteristic of Hodgkin's disease. Clinical observation has determined that the lymph nodes enlarge during periods of fever and reduce in size as the fever subsides. To our knowledge, the waxing and waning of lymph nodes in tempo with the fever cycle in Hodgkin's disease have never before been documented by lymphography. The alterations we verified radiographically resemble cyclic swings in classic autoimmune diseases. Speculations are offered regarding the observed changes.
