We present a rare case of large bilateral ovarian tumours, secondarily revealing an ileal neuroendocrine tumour in a 71-year-old woman. Magnetic resonance examination showed bilateral ovarian, entirely solid lesions with a fibrous content and marked enhancement. Computed tomography was able to show a mesenteric retractile mass and a satellite suspicious ileal wall thickening. Gallium-68 DOTATOC confirmed the suspicion of digestive neuroendocrine tumour metastatic to the ovaries and the final diagnosis was made following radical surgery. To the best of our knowledge, the mainly fibrous aspect at imaging, resembling that of the primary tumour, is the first to be described in English literature. Therefore, we think that in the presence of atypical bilateral, solid and mainly fibrous ovarian masses, careful search for a primary lesion along the digestive tract should be conducted.
