患者：男，64岁最终诊断：肺多形性癌症状：咳嗽•发烧用药：-临床程序：-专科：肿瘤学临床病程异常若病理检查（如支气管镜检查）不能确诊肺癌，通常根据CT图像诊断。然而，癌性病变的CT表现与脓肿相似。我们在此报告一例肺癌在CT上表现为肺脓肿。我们在此描述的情况下，64岁的男性谁被诊断为肺癌使用手术。本例在CT上很难区分肺癌和肺脓肿，最初怀疑是肺脓肿，主要是由于发热、咳嗽等症状，CT增强显示右上叶环状增强肿块，以及患者实验室检查结果。然而，根据病变的快速冷冻切片活检结果证实了肺癌的病理诊断。本病例提示医生不应同时怀疑肺脓肿和恶性肿瘤，当肿块在增强CT上表现为环形增强病变时。
Patient: Male, 64 Final Diagnosis: Lung pleomorphic carcinoma Symptoms: Cough • fever Medication: — Clinical Procedure: — Specialty: Oncology Unusual clinical course The diagnosis of lung cancer is often made based on computed tomography (CT) image findings if it cannot be confirmed on pathological examinations, such as bronchoscopy. However, the CT image findings of cancerous lesions are similar to those of abscesses.We herein report a case of lung cancer that resembled a lung abscess on CT. We herein describe the case of 64-year-old male who was diagnosed with lung cancer using surgery. In this case, it was quite difficult to distinguish between the lung cancer and a lung abscess on CT images, and a lung abscess was initially suspected due to symptoms, such as fever and coughing, contrast-enhanced CT image findings showing a ring-enhancing mass in the right upper lobe and the patient’s laboratory test results. However, a pathological diagnosis of lung cancer was confirmed according to the results of a rapid frozen section biopsy of the lesion. This case suggests that physicians should not suspect both a lung abscesses and malignancy in cases involving masses presenting as ring-enhancing lesions on contrast-enhanced CT.
