Mitral-aortic intervalvular fibrosa aneurysm is a rare disease entity whose aetiology remains uncertain. Most of the cases reported are believed to be a sequela of infective endocarditis. We present a case of congenital mitral-aortic intervalvular fibrosa aneurysm, representing the first patient to be diagnosed at birth in the literature. This report illustrates the imaging features of mitral-aortic intervalvular fibrosa aneurysm and the role of multidetector computed tomography in the diagnostic process.

二尖瓣-主動脈瓣瓣間纖維膜動脈瘤是一種罕見疾病,病因至今仍然不明。大多數病例認為是感染性心內膜炎的後遺症。本文報告了一例二尖瓣-主動脈瓣瓣間纖維膜動脈瘤的病例,病人出生時已即診斷此症,是文獻中首個類似病例報告。本報告描述此病例的影像學特徵,以及診斷此症時多層螺旋CT掃描的作用。
