| Abstract: | This study demonstrated magnetic resonance imaging (MRI) and computed tomography for
large-sized splenic hemangiosarcoma. Radiography and ultrasonography revealed the presence
of a large-sized soft-tissue mass in the cranial abdomen. Computed tomography showed
hypoattenuating mass. The mass was located in contact with liver, spleen and stomach, and
the origin of the mass remained ambiguous. The mass was T2-hyperintense and T1-hypointense
with mild contrast enhancement. MRI allowed a differentiation between large-sized tumor
and neighboring normal structure, and the mass was consequently identified as arising from
spleen. These results suggested that MRI might be a useful tool to visualize large-sized
splenic tumors and improve the accuracy of diagnosis. |
