It demonstrated FDG avid lymphadenopathy above and below the diaphragm [Figures 1 and 2].
Axial PET(a), low dose CT(b) and fused PET/CT(c) images showing enlarged hypermetabolic mediastinal lymph nodes (e.g., right paratracheal, maximum standardized uptake value 3.9). Similar enlarged FDG avid lymph nodes were seen involving multiple lymph node groups including right intraparotid, cervical, lung hilum, splenic hilum, mesenteric, and inguinal nodal stations

It demonstrated FDG avid lymphadenopathy above and below the diaphragm [Figures 1 and 2].
Axial PET(a), low dose CT(b) and fused PET/CT(c) images images showing a hypermetabolic lesion in the spleen (maximum standardized uptake value 2.4) with no definite low dose computed tomography correlate

A focus of increased FDG uptake was also noted in the enlarged spleen [Figure 3], which showed hypoechoic lesions on ultrasound [Figure 4].
Sonogram of the abdomen showing splenomegaly (a), diffusely heterogeneous spleen and with hypoechoic subcentimeter splenic nodules (b), which could be secondary to fungal infection or multiple abscesses
