Phrenic Nerve Paralysis as the Initial Presentation in Pleural Sarcomatoid Mesothelioma

چکیده
A 74-year-old man was referred to our hospital because of persistent cough. A chest radiograph revealed an elevation of the right diaphragm. Computed tomography (CT) images revealed a small nodule localized on the right mediastinum. Five months later, the nodule had grown and was diagnosed as malignant pleural mesothelioma (MPM) by a CT-guided needle biopsy. The patient underwent combined chemotherapy, but the disease progressed rapidly and he passed away. On autopsy, microscopic findings and immunohistological examinations supported the diagnosis of sarcomatoid mesothelioma. Therefore, we diagnosed this rare case as localized sarcomatoid MPM showing phrenic nerve paralysis as an initial presentation.

Post-operative respiratory failure due to bilateral phrenic nerve palsy.
A 65 year old female patient developed a large left pleural effusion and a sternal split dehiscence following aorto-coronary artery bypass grafting. A second operation was performed to investigate and drain the pleural effusion and to repair the sternum. Subsequent to this operation the patient was in acute respiratory failure due to bilateral phrenic palsy. It is probable that the left phrenic...
متن کاملSarcomatoid Type Primary Pericardial Mesothelioma with a Long-term Survival after the Onset of Cardiac Tamponade
Primary pericardial malignant mesothelioma is a very rare clinical entity and its prognosis is very poor. We herein report a 67-year-old man who presented with pericardial mesothelioma that was diagnosed 21 months after the onset of cardiac tamponade as the initial manifestation. Despite undergoing pericardiocentesis and surgical pericardial fenestration at the onset of cardiac tamponade, we we...

Study Design Case report. Objective Malignant mesothelioma (MM) is an uncommon tumor of the pleural epithelium with a predilection for local spread into adjacent tissues. The sarcomatoid type accounts for ∼10% of MM cases and is associated with poorer survival than the epithelioid, desmoplastic, and biphasic types. MM commonly presents with involvement of the vertebral body or epidural space. H...

A 62-year-old man was admitted to the emergency department with chronic dysphagia and lower back pain. Chest radiography revealed a wide mediastinal shadow and an elevated left diaphragm, which proved to be secondary to left phrenic paralysis. The patient was diagnosed with an aneurysm of the descending thoracic aorta and was admitted to the hospital. After the patient was admitted, the aneurys...
