The magnetic resonance imaging findings of the mass. a–d The MRI imaging findings of the mural nodule of the tumour. e–h The MRI imaging findings of the septal nodule of the tumour. a and e T1-weighted MR images; b and f T2-weighted MR images; c and g on Gadolinium-enhanced T1-weighted MR images at arterial phases, the mural and septal nodule of the tumour showed heterogeneous enhancement. d and h The papillary excrescences of the tumour (arrow) showed high signal intensity on diffusion weighted imaging. The pathological finding was high-grade serous adenocarcinoma
