Pseudoaneurysm of the aortic arch: A rare case report of pulmonary cancer complication.

BACKGROUND: Pseudoaneurysm of the aortic arch is uncommonly associated with cancer, and is extremely rare in pulmonary cancer. Here, we report an unusual and successfully treated case of aortic arch pseudoaneurysm in a male patient with lung squamous cell carcinoma. METHODS: A 64-year-old male patient was admitted to the Emergency Department, presenting with massive hemoptysis (>500 mL blood during the 12 hours prior to treatment). The diagnosis of aortic arch pseudoaneurysm was confirmed after inspection of computed tomographic angiography and three-dimensional reconstruction. We processed the immediate endovascular stent-grafting for this patient. RESULTS: This patient recovered with no filling or enlargement of the pseudoaneurysm, no episodes of hemoptysis, and no neurological complications during the 4-week follow-up period. CONCLUSION: Herein, we compare our case with other cancer-related pseudoaneurysms in the medical literature and summarize the clinical features and treatment of this unusual case.

Successful treatment of patients with paraquat intoxication: three case reports and review of the literature.

OBJECTIVE: To report on three patients with paraquat (PQ) intoxication surviving after combined therapy with hemoperfusion (HP), cyclophosphamide (CTX), and glucocorticoid. METHODS: Three patients suffered acute renal failure in a few days after ingesting a lethal amount of PQ. Chest computed tomography (CT) scans revealed obvious pulmonary inflammation, pleural effusion, and fibrous lesions several days after ingestion. HP was performed immediately, followed by large doses of glucocorticoid (methylprednisolone, 500 g/d) and CTX (approximately 4 g). RESULTS: After 50 d of treatments, all three patients were discharged in healthy condition, with chest CT showing small fibrous lesions, exudation, and both lungs clear of auscultation. CONCLUSIONS: The protective effect of the lungs may have been due to timely treatment at adequate doses.

Pulmonary epithelioid haemangioendothelioma mimicking central lung cancer.

A 40-year-old woman was hospitalized for investigation of dry cough, dyspnoea, and pain and swelling in the large joints of the arms and legs. Chest CT revealed a left hilar mass with partial atelectasis in the apical segment of the left lower lobe. X-ray of the wrists, elbows, ankles and knee joints showed a periosteal reaction, associated with hypertrophic pulmonary osteoarthropathy. Endobronchial biopsy suggested a pulmonary epithelioid haemangioendothelioma. Whole left lung resection was performed and the patient died of respiratory failure 1 month postoperatively.
