case_images: (a) CT scan showing swellings in the lymph nodes (arrows). (b) Low-density areas in the spleen were also observed (arrows), suggesting metastasis from a malignant tumor of the left ovary.

case_images: The CT scan also revealed a > 10-mm lymph node swelling in the dorsal pancreas (Fig. 1a) and multiple low-density areas in the spleen (Fig. 1b).
case_images: (a) 18FDG avidity was observed in the lymph nodes (arrows) and (b) in the spleen (arrows).

case_images: Following whole body 18F-fluorodeoxyglucose positron emission tomography (FDG-PET), elevated FDG uptake was reported in the left adnexa, in the lymph nodes along the iliac arteries, in the dorsal pancreas and spleen (Fig. 2a,b).
case_images: (a) Microscopic findings of the resected ovarian tumor and lymph nodes. Atypical cells with clear cytoplasm grew papillary, tubulocystic, and focally solid pattern (hematoxylin and eosin [HE]). (b) Non-caseating epithelioid granulomas were observed in the pelvic lymph node as well as in the spleen where there were no metastatic lesions (HE).

case_images: Specifically, a distinct hobnail pattern was observed (Fig. 3a). Histopathological examination of the resected lymph nodes and spleen revealed a non-caseating epithelioid cell granuloma (Fig. 3b), wherein no tumor cells were identified.
