, Seok Ho Seo, Seung Hyun Lee, Dae Won Park, Dong Goo Kang, Seung Uk Lee Stress-induced cardiomyopathy, so-called Takotsubo cardiomyopathy, has recently been reported in Japan. Stress-induced cardiomyopathy is characterized by transient left ventricular apical dysfunction and ballooning, with normal coronary angiographic findings. We describe a rare case of stress-induced cardiomyopathy associated with lung adenocarcinoma presenting as hyponatremia.

Unlike low-grade tumor with benign nature, high-grade case is even rarer and has aggressive clinical features with no definite treatment option. Here, we report a case of high-grade pulmonary MEC with fulminant clinical course. A 74-year-old man presented with cough, sputum and mental change. Chest imaging showed massive mediastinal lymphadenopathy with obstructive pneumonia, and multiple metastases in lung and adrenal gland. Bronchoscopy showed polypoid masses obstructing right main bronchus and bronchus intermedius. Histopathology revealed a mixture of glandular structure lined with mucussecreting cells and nests of squamoid cells with nuclear atypia and pleomorphism, which is compatible with high-grade MEC. We intensively treated the patient with combination antibiotics and ventilator care. However, the patient did not respond to the treatment and rapidly deteriorated, and finally expired a month after diagnosis.

The causes and pathophysiological mechanism of this condition are poorly understood, but it has a benign clinical course and recovers spontaneously. However, in some cases, this condition may cause cardiovascular collapse resulting in major ischemic organ injury and be life threatening. Herein we report a case and review literature, regarding completing anesthesia safely during an elective surgery of a 59-year-old female patient with history of loss of consciousness due to suspected vasovagal syncope followed by cardiovascular collapse and cardiac arrest, which required cardiopulmonary resuscitation and insertion of a temporary pacemaker and intra-aortic balloon pump immediately after a fine-needle aspiration biopsy of a lung nodule located in the right middle lobe.
