Abstract

Radiofrequency ablation has been applied as a minimally invasive therapy for the local control of lung tumors, including primary and metastatic neoplasms. Hemorrhagic complications after radiofrequency ablation can usually be treated conservatively, but such complications can be massive and fatal in some cases. In this paper, we report the rare case of delayed massive hemothorax caused by the rupture of a pulmonary artery pseudoaneurysm after lung radiofrequency ablation that was treated using transcatheter coil embolization followed by a left lower lobectomy. A 75-year-old woman underwent radiofrequency ablation for the treatment of a metastatic lung tumor in the left lower lobe arising from a colorectal carcinoma located close to a branch of the pulmonary artery. Thirty-six hours later, hemothorax and hemorrhagic shock occurred as a result of a ruptured pulmonary artery pseudoaneurysm and radiofrequency ablation-induced damage to the interlobular pleura. After transcatheter coil embolization of the pulmonary artery pseudoaneurysm, she recovered from a state of shock and a left lower lobectomy was performed. Histological findings revealed the presence of residual tumor cells in the ablated lung tumor. The postoperative course ...Continue Reading

Cajal Bodies & Gems

Cajal bodies or coiled bodies are dense foci of coilin protein. Gemini of Cajal bodies, or gems, are microscopically similar to Cajal bodies. It is believed that Cajal bodies play important roles in RNA processing while gems assist the Cajal bodies. Find the latest research on Cajal bodies and gems here.
