A CT scan of the chest, abdomen, and pelvis revealed lymph nodes of over 1 cm in size in the paratracheal, subcarinal, and intrapulmonary areas (A), and numerous lymph nodes of varying size, which were enhanced in the hepatic hilum, peripancreatic area, celiac axis, and paraaortic area (B).

A computed tomography (CT) scan of the neck and chest revealed masses adjacent to both sternocleidomastoid muscles, numerous lymph nodes of varying size in both axillary areas, and over lymph nodes of over 1 cm in size in the paratracheal, subcarinal, and intrapulmonary areas (Figure 1A). A CT scan of the abdomen and pelvis displayed multiple lymph nodes of varying size, which were enhanced in the hepatic hilum, peripancreatic area, celiac axis, and paraaortic area (the largest was 4.5 cm) (Figure 1B).
A tumor scan using Gallium-67 demonstrated more noticeable increased uptake lesions in the left lower cervical, left axillary, paraaortic, right iliac, and both inguinal lymph nodes.

A tumor scan using Gallium-67 demonstrated more noticeable increased uptake lesions in the left lower cervical, left axillary, paraaortic, right iliac, and both inguinal lymph nodes (Figure 2).
Histopathology of the neck mass and lymph nodes revealed dense infiltration of eosinophils, lymphocytes, histiocytes with a profusion of small vessels, and mild fibrosis (HE stain, A:x200, B:x400).

Results of histopathological examinations of the neck mass and lymph nodes revealed dense infiltration of eosinophils, lymphocytes, and histiocytes, along with many small vessels, mild fibrosis, and results consistent with KD, with no evidence of malignant lymphoma (Figure 3).
A follow-up abdominal CT scan showed near-complete resolution of abdominal lymph nodes.

After two months, physical examination revealed no neck masses, and a follow-up abdominal CT scan showed that the numerous lymph nodes of varying size had subsided spontaneously (Figure 4).
