Fig. 1From: Cytokeratin-positive interstitial reticulum cell (CIRC) tumor in the lymph node: a case report of the transformation from the epithelioid cell type to the spindle cell typeEnhanced computed tomography revealed swelling of the right upper paratracheal lymph node (a, arrow) and right lower paratracheal lymph node (b, arrow). Abnormally high uptake in the right supraclavicular lymph node (c, arrowhead) and right lower paratracheal lymph node (d, arrowheads) was detected by positron emission tomography/computed tomography. The right lower paratracheal lymph node was the main lesion, which was approximately 2.7 cm in size. The right upper paratracheal lymph node and right supraclavicular lymph node were metastatic lesions and showed slight swellingBack to article page
