肝内富血管性假性病灶,如动脉门静脉短路(AP)并非少见。作者回顾了1995～1996年间的9例肝硬化伴富血管性假性病灶的单层动态高分辨肝动脉造影CT(D-CTA),其中1个假性病灶(42mm)是因为血管造影前3天作肝脏细针活检而引起的AP短路,2个病灶(20及16mm)为继发于海绵状血管瘤的AP短路,余6个病灶(14～20mm)经影像随访至少1年后证实。同时有9例因肝硬化作D-CTA,该组织学证实为HCC(13～43mm,平均27.8mm)。该组病例是经过超声、CT、MRI已
Intravascular hepatic pseudo-focal lesions such as arterial portal vein short-circuiting (AP) are not uncommon. The authors reviewed 9 cases of single-layer dynamic high-resolution hepatic arteriography (D-CTA) with cirrhosis and vascular pseudo-focal lesions between 1995 and 1996, of which 1 pseudo-lesion (42 mm) The AP was short-circuited by needle biopsy of the liver. Two lesions (20 and 16 mm) were short-circuited to AP secondary to cavernous hemangioma, and the remaining six lesions (14-20 mm) were confirmed by imaging at least 1 year after follow-up. There were also 9 cases of D-CTA due to liver cirrhosis. HCC was confirmed histologically (13-43 mm, mean 27.8 mm). The group of patients after ultrasound, CT, MRI has been
