MRI study shows a left postero-lateral lower chest/ upper abdominal huge soft tissue mass lesion measures 14x15x20 cm along its largest axial and cc dimensions.
- anterosuperior, the mass is seen exerting mass effect on the lower lung base and pleura smoothly displacing them. Associated minimal pleural effusion is noted
- postero-lateral: the mass is seen violating the lower chest and upper abdominal wall, bulging externally
- medially, the mass is seen displacing the spleen and reaching the left paraspinal region
- inferiorly, the mass is seen reaching the left lumbar region, indenting the lateral cortex of the left kidney
It elicits markedly heterogeneous signal intensity in T1 and T2 with internal hemorrhagic and cystic areas. Heterogeneous enhancement is noted in the post-contrast study
