“…Yoshimura et al (25) reported that the diagnostic accuracy is 91% in nodules over 8 mm in size and 64% in those under 8 mm in size. However, the diagnostic accuracy for nodules under 1 cm has been reported to be 70% with CT-guided biopsy, compared with just 44% for transbronchial lung biopsy (26, 27). Unfortunately, pneumothorax can occur in 15-25% of the cases undergoing CT-guided biopsy, whereas hemoptysis can occur in 2-6% (28, 29).…”

CT-guided Biopsy for the Diagnosis of Pulmonary Epithelioid Hemangioendothelioma Mimicking Metastatic Lung Cancer

A 69-year-old male patient presented with multiple lung nodules revealed by chest-computed tomography (CT) during a preoperative examination for an appendiceal tumor. The nodule diameters ranged from 2-10 mm without either pleural thickening or effusions. A fluorine-18-labeled fluorodeoxyglucose (F-FDG)-positron emission tomography (PET)/CT scan showed a high FDG uptake in the appendiceal tumor, but almost normal standardized uptake values in the bilateral lung nodules. A CT-guided biopsy led to a diagnosis of pulmonary epithelioid hemangioendothelioma, a rare vascular tumor with a radiological presentation similar to that of a metastatic lung tumor. The present case is the first to describe successful treatment using a CT-guided biopsy instead of more conventional methods.
