Fig. 2From: Endometriosis-associated clear cell carcinoma arising in caesarean section scar: a case report and review of the literaturePre-surgical T2-weighted FSE sagittal MRI (a) documenting a supra-vesical pelvic mass extending into the anterior pelvic wall and showing non-homogeneous signal intensity and solid components. Sagittal CT (b) and fused 18F-FDG PET/CT (c) images showed non-homogeneous uptake in the 22 cm abdominal mass: in particular, intense abnormal 18F-FDG uptake was present in the caudal solid component of the mass, whereas an absent area of tracer uptake was evident in its cranial fluid component. Corresponding T2-weighted FSE axial MRI (d) confirmed the presence of a solid and partially fluid pelvic mass, and enlarged loco-regional lymph nodes (arrow). Axial CT (e) and fused 18F-FDG PET/CT images (f) showed intense tracer uptake in the solid component of the mass, extended up to the skin surface of pelvis, and enlarged left external iliac lymph-node, characterized by increased tracer uptake (arrows)Back to article page
