title: Multiple regenerative nodular hyperplasia in the left infrarenal vena cava accompanied by Abernethy malformation.
abstract: The current study presents the case of a 19-year-old male patient who was detected with an increased alanine aminotransferase and aspartate transaminase levels during a preoperative evaluation of the right inguinal hernia operation and was later found to have Abernethy malformation accompanied by multiple regenerative nodular hyperplasia and left intra renal inferior vena cava. Regenerative nodular hyperplasia accompanying these two abnormalities is extremely rare and to the best of our knowledge, such a case has not been reported to date. Abdominal ultrasound (US) and color Doppler US, dynamic abdominal magnetic resonance imaging (MRI), and portography examinations were performed and a type 2 Abernethy malformation, partial malrotation of the inferior vena cava, and regenerative nodular hyperplasia were detected. We aimed to discuss the radiological signs of these two accompanying abnormalities with a literature review.
