We recently encountered two cases that suggested that Levovist, an intravenous contrast agent, was useful for its ability to enhance color signals in the color Doppler ultrasonographic imaging in subpleural lung cancer, especially in lung cancer with relatively poor flow and tortuous color flow in part of the lesion. Case 1 was that of a 66-year-old woman in whom a tumor shadow was detected in S1+2 of the left lung. The diagnosis of squamous cell carcinoma of the lung was based on the results of broncoscopic examination. The B-mode ultrasonogram showed a hypoechoic tumor with pleural invasion. Power Doppler US color flow patterns indicated tortuous color flow in part of the lesion. Power Doppler ultrasonograms acquired after injection of Levovist showed enhanced color flow signals inside and around the periphery of the tumor. Color flow signals increased from the partial to the whole type. Case 2 was that of a 69 year-old man with a mass shadow in S1+2 of the left lung. The diagnosis of squamous cell carcinoma of the lung was based on results of broncoscopic examination. The B-mode ultrasonogram showed a hypoechoic tumor with pleural invasion. The power Doppler US color flow pattern indicated tortuous color flow in part of the lesion. Power Doppler ultrasonograms acquired after injection of Levovist showed enhanced color flow inside and around the periphery of the tumor. Color flow pattern did not change after injection of Levovist . These two cases suggest that Levovist is useful in detecting the vessels of subpleural lung cancer.
