CT scan at transverse plane (a) and coronal plane (b) showing a 1.4 cm left level 5 A lymph node. No other adenopathy. No mass along the course of the aerodigestive tract. Cervical lymph node biopsy demonstrating lymph node with follicular hyperplasia, phagocytosis of nuclear debris, noncaseating epithelioid granuloma, and sinusoidal distension by plasma cells and immunoblasts (c) (x10 magnification). Higher magnification of the epithelioid granulomas (d) (x40 magnification).

Repeat neck CT revealed the 1.4 cm lymph node, unchanged from previous (Figures 1(a) and 1(b)). Biopsies of the abnormal lymph node were taken (Figures 1(c) and 1(d)). The histopathological examination revealed noncaseating epithelioid granulomas (Figure 1(d)), and Gomori methenamine silver (GMS) stain was consistent with Toxoplasma gondii bradyzoite (Figure 2).
