Abstract:
Objective:To retrospectively analyze the contrast-enhanced ultrasound(CEUS) features of primary hepatic lymphoepithelioma-like carcinoma (LELC) and investigate the value of CEUS in the diagnosis of hepatic LELC.Methods:The images of CEUS of 12 cases with hepatic LELC were retrospectively analyzed. The perfusion patterns and time of enhancement were observed.Results:During the arterial phase, 11 lesions showed diffuse enhancement, while 1 lesion showed rim-like enhancement. The mean time of begin enhancement, time to peak, time to iso-enhancement and slightly hypo-enhancement were (17.92±5.81)s, (24.50±5.52)s, (29.55±6.25)s, (45.50±25.15)s, respectively. Compared with adjacent liver parenchyma, rapid enhancement was observed in 11 lesions and synchronous enhancement was observed in 1 lesion.As to time of peak enhancement, hyper-enhancement and iso-enhancement were observed in 11 lesions and 1 lesion, respectively. In portal phase, 8 lesions manifested slight hypo-enhancement, 3 lesions with marked hypo-enhancement and 1 lesion with iso-enhancement.And in delayed phase, 10 lesions showed marked hypo-enhancement and 1 lesion with slight hypo-enhancement. Ten lesions showed peripheral hyper-enhancement like a bright ring in the portal and delayed phase.Conclusions:CEUS is valuable for the diagnosis and differential diagnosis of hepatic LELC.
