case_images: Maximum Intensity Projection (MIP) image (a) shows physiological tracer uptake in the brain, kidney, and urinary bladder. Abnormal FDG uptake is observed in the entire peritoneum with nodules (red arrow). Axial section Fused PET/CT images (b, c) and axial CT images (e, f; red arrow) show diffuse thickening of the peritoneum, omental caking with increased FDG uptake and gross ascites. Axial section Fused PET/CT (d; blue arrow) and axial CT (g; blue arrow) from the pelvis indicate a narrowing of the sigmoid colon with increased uptake proximally. Postoperative histopathology confirmed Ca Sigmoid colon. Further axial PET/CT images (h, j) and corresponding Axial CT images (i, k) reveal mesenteric stranding with nodules and increased FDG uptake. Both sections also show FDG avid ascites; all these findings are PC characteristics

case_images: Diffuse peritoneal thickening with extensive nodular omental stranding was also noted (Figure 1).

case_images: FDG PET/CT Maximum Intensity Projection Images (a) in a Post-op Case of Ca ovary reveals increased FDG uptake in the peritoneum with multiple nodularities (Blue and green arrow). Fused Axial PET/CT images (b,c) revealed diffuse peritoneal thickening with increased FDG uptake (blue arrow); peritoneal and serosal deposits (green arrow) in and dilated duodenal loops were also noted (yellow arrow). Further Axial fused PET/CT images (d, e, f) revealed multiple peritoneal deposits (green arrow), mesenteric nodularity (blue arrow), intraperitoneal fluid collection (red arrow), and dilated duodenal loop. Coronal fused PET/CT image (g) revealed FDG avid peritoneal thickening, mesenteric nodularity, Serosal deposits, intraperitoneal fluid collection, and dilated bowel loops (yellow) suggestive of peritoneal carcinomatosis

case_images: The 18FDG PET/CT with contrast showed ascites with FDG avid variable sizes peritoneal, mesenteric, and serosal soft tissue deposits (Figure 2).

case_images: Maximum Intensity Projection image (a) revealed increased FDG uptake in the peritoneum (Green arrow) with nodularity and multiple FDG avid abdominal nodes (blue arrow) and a left supraclavicular lymph node (Red arrow). Axial section Fused FDG PET/CT (b, c) revealed gross ascites with FDG avid peritoneal thickening (green arrow), Multiple FDG avid abdominal nodes (blue arrow), and left supraclavicular lymph node (red arrow). Axial Fused PET/CT (d) from the pelvis revealed increased FDG uptake in the endometrium cavity. Axial Fused FDG PET/CT images (e, f, g) and corresponding CT (h, i, j) revealed diffuse peritoneal thickening with peritoneal and serosal deposits, omental thickening with increased FDG uptake (green arrow), and ascites. Fused Axial PET/CT (e) and corresponding CT images (h) revealed a solid cystic lesion in the bilateral adnexal region with increased FDG uptake in the solid component of the left adnexa (e, green arrow)

case_images: These imaging findings suggested a primary ovarian malignancy with PC (Figure 3).
case_images: Maximum Intensity Projection (a) image revealed diffuse increased uptake in the peritoneum with few FDG avid nodules and increased FDG uptake in the bilateral adnexal region. (Green arrow). Axial section Fused FDG PET/CT images (b, c, d) and corresponding axial CT images (e, f, g) revealed omental thickening, omental nodules, few peritoneal deposits, and mesenteric thickening with nodularity. Ascites can also be noted in all these sections. Further Fused Axial PET/Ct images (h, j) and axial CT images (I, k) revealed omental caking and peritoneal thickening with increased FDG uptake (red arrow) and ascites. A fused axial PET/CT image (j) and corresponding axial CT image (k) also revealed an FDG avid bilateral adnexal lesion with pelvic ascites

case_images: Extensive lymphadenopathy, gross ascites, and peritoneal and omental thickening were noted as indicative of PC (Figure 4).
