Intussusception caused by small intestine metastasis of malignant pleural mesothelioma: a case report.

Abstract

Malignant pleural mesothelioma (MPM) is an aggressive form of malignant tumor that originates in the pleural mesothelioma and presents as a local disease in the affected hemithorax. Small intestine metastasis is a rare complication. Herein, the case of a patient with jejunal intussusception caused by small intestine metastasis of MPM has been reported. A 72-year-old man with MPM was admitted to our hospital for abdominal pain. Computed tomography revealed small intestine intussusception. An emergency surgery was performed, and the tumor and intussusception were located in the upper jejunum. Histopathological examination of the resected jejunum revealed that the tumor was a small intestinal metastasis of the MPM from the chest wall. This case showed that MPM may metastasize to the small intestine, and metastatic tumors may cause intussusception.
