Ultrasonography showed splenomegaly (10.8 x 6.6 cm), with a solid, hypoechoic splenic mass (8.0 x 7.0 cm) (Fig. 1a, b). Color doppler ultrasound showed blood flow within the mass (Fig. 1c).

Ultrasonography revealed splenomegaly (10.8 x 6.6 cm), and a solid, hypoechoic mass (8.0 x 7.0 cm) in the spleen (Fig. 1a, b). Color doppler ultrasound demonstrated blood flow within the mass (Fig. 1c).
Abdominal computed tomography (CT) revealed an isodense splenic mass (a). Contrast- enhanced CT showed heterogeneous enhancement of a solid splenic mass (8.0 cm) during the arterial phase (b). The mass was isodense compared to normal splenic parenchyma in the portal phase (c). PET-CT showed no significant FDG accumulation within the mass (d).

Abdominal computed tomography (CT) showed an isodense splenic mass (Fig. 2a). Contrast- enhanced CT showed heterogeneous enhancement of the mass in the arterial phase (Fig. 2b). The mass was isodense compared to normal splenic parenchyma in the portal phase (Fig. 2c). Positron emission tomography (PET)-CT showed no significant fludeoxyglucose (FDG) accumulation within the mass (Fig. 2d).
The resected specimen showed a localized, well-demarcated splenic mass (8.0 x 7.0 cm) (Fig. 3a,b). Hematoxylin- eosin stain revealed abnormal red pulp proliferation and the absence of normal splenic structures. No extramedullary hematopoiesis was observed (Fig. 3c,d).

The resected specimen showed a localized, well-demarcated, 8.0 x 7.0 cm splenic mass (Fig. 3a,b). No extramedullary hematopoiesis was observed (Fig. 3c,d).
