If a case with malignant lymph nodes (LNs) is misdiagnosed as sarcoid reaction, the underestimation of the malignancy can lead to insufficient treatment that will affect the patient's disease morbidity and mortality. Lymph fluid builds up in lymph nodes in an effort to trap bacteria, viruses, or other harmful pathogens. Often invade basal membrane that surrounds nearby healthy tissue. None of the ARFI parameters could reliably differentiate among the malignant lymph node subgroups, namely, lymphoma and metastatic nodes, though all five nodes with indeterminate SWV values were solid on grey scale and metastatic on histopathological examination (HPE).
