The patient 66 years old female came to the screening ultrasound of the breast, no additional lesions were found in the mammary glands. But single axillary LNs(lymph nodes) of an atypical structure (mainly hyperechoic with an unclear contour - replacement by fat? Other?) were found on both sides, up to 2 cm in length, on the CFM on the one side with blood flow. PS. Some people think that replacement LNs by fat is practically always the age norm, but - " abundant replacement of the lymph node with fat is highly unusual and may appear as metastatic lymph node disease in the course of fat-predominant liposarcomas or in the case of coeliac disease complicated by cavitating lymph node syndrome. In this case report, a patient with chronic lymphocytic leukaemia/small lymphocytic lymphoma who demonstrated an increasing abundance of macroscopic fat in the diseased lymph nodes is presented." external link |
