Positron emission tomography/computed tomography findings of multiple cystic lymphangiomas in an adult: A case report

Figure 1 Contrast–enhanced abdominal-pelvic computed tomography and whole body positron emission tomography computed tomography images. A and B: Axial contrast–enhanced computed tomography images showing multiple well-defined hypodense cystic lesions (orange arrows) arising from the retroperitoneum (A) and pelvic space (B) without enhancement. The lesions grew along the peritoneal interstitial space, the pelvic wall, and external iliac vascular deformation area, some of which showed shaping and suture-like changes. The biggest one was 3.3 cm × 2.5 cm. C and D: Positron emission tomography/computed tomography performed 1 h after injection of (10 mCi) 370 MBq of F-18-fluorodeoxyglucose showing that there was no uptake by the multiple retroperitoneum and pelvic masses.
