Fig. 2.

Axial T1-weighted sequence without fat saturation (A) and fat saturated, contrast enhanced MRI image (B) show a left axillary lymph node with lack of fat in the hilum, at level I (arrow). Bilateral T2-weighted short tau inversion recovery (STIR) MRI reconstructed axial (C) demonstrate hyperintense T2 signal in the left axilla asymmetric compared to the right axilla, compatible with edema. Bilateral axillary grayscale ultrasound, transverse plane (D,E) shows left-sided lymph node with thickened cortex but no edema is identified (D), which underwent FNA (single arrow – lymph node; double arrow - needle) (E). Magnified image of Pap-stained ThinPrep slide (F) showing polymorphous lymphoid population with follicular germinal center fragments.
