Typically, it is caused by infiltration of metastatic tumors arising from the stomach, ovary, or colon. This dissemination of cancerous cells that do not originate from the omentum itself is called peritoneal carcinomatosis. It can occur other regional tumors such as lymphoma where it is associated with regional lymphadenopathy. It can also rarely occur as a result of infectious causes such as tuberculous peritonitis, peritoneal coccidioidomycosis, and histoplasmosis.
