Malignant peritoneal mesothelioma with lower extremity metastasis: PET/CT imaging.
Malignant peritoneal mesothelioma is usually confined to the abdomen and pelvis. Extra-abdominal and extrapelvic dissemination is very uncommon mostly at advanced stages of the disease. This rare clinical event may be related to contiguous spread through connecting pathways linking the abdomen and pelvis to the thorax and proximal lower extremity. The authors present a case of advanced malignant peritoneal mesothelioma with contiguous dissemination to the right thigh and proximal leg documented and monitored by F-FDG PET/CT imaging.
