A 75-year-old man presented to the emergency department with 1-day history of right lower limb pain and 3-month history of vague abdominal pain. In the emergency department a thrombus was discovered in the right popliteal artery. CT scan of the abdomen and pelvis revealed high-density material in the pelvis, multiple hypodensities on the liver, ascites with omental nodularity, and high-density material along the stomach wall. He underwent thrombectomy and was started on anticoagulation therapy. The core needle biopsy revealed primary omental mesothelioma. There was no history of any known asbestos exposure. He also had to undergo therapeutic paracentesis twice due to abdominal distension. Mesothelioma treatment of carboplatin and pemetrexed was started, and the patient is currently receiving this chemotherapy treatment regimen.
