摘要

大多数转移性胸膜病变是由恶性肿瘤引起的，如支气管源性癌（40%）、乳腺癌（20%）、淋巴瘤（10%）和卵巢癌或胃癌（5%）。然而，胸腺瘤的胸膜转移极为罕见。在本报告中，我们报告了一例胸腺瘤合并广泛胸膜转移的患者的18f -氟脱氧葡萄糖（18F-FDG）正电子发射断层扫描/计算机断层扫描（PET/CT）成像结果。尽管活检仍然是诊断的金标准，但在鉴别诊断中考虑高级别胸腺瘤是很重要的，因为在18F-FDG PET/CT成像上观察到广泛的胸膜受累可以模拟原发性和转移性胸膜恶性肿瘤。认识到这种可能性有助于更准确地解释影像学表现。

¹⁸F-FDG PET/CT Detection of Extensive Pleural Metastasis in Rare Malignancy Thymoma.

The majority of metastatic pleural lesions are caused by malignancies such as bronchogenic carcinoma (40%), breast cancer (20%), lymphoma (10%), and ovarian or gastric carcinomas (5%). However, pleural metastases from thymoma are extremely rare. In this report, we present the ¹⁸F-fluorodeoxyglucose (¹⁸F-FDG) positron emission tomography/computed tomography (PET/CT) imaging findings of a patient with thymoma and extensive pleural metastases. Although biopsy remains the gold standard for diagnosis, it is important to consider high grade thymoma in the differential diagnosis, as extensive pleural involvement observed on ¹⁸F-FDG PET/CT imaging can mimic both primary and metastatic pleural malignancies. Recognizing this possibility can assist in more accurate interpretation of imaging findings.
