| Abstract (English): | Background: Abernethy malformations are vascular developmental anomalies characterized by hypoplasia or agenesis of the portal vein. These malformations have a variable clinical presentation due to associated complications and are often diagnosed incidentally through imaging studies, primarily in pediatric patients. Case Summary: We report the case of a 39-year-old female patient who presented with spider telangiectasias. Laboratory tests revealed pancytopenia and elevated liver transaminases. Given the complexity of the case, autoimmune diseases and portal vein thrombosis were ruled out through autoantibody testing and Doppler ultrasound. Incidentally, triphasic computed tomography of the abdomen revealed splenomegaly, an aneurysm of the inferior segmental artery of the left kidney, splenorenal collaterals, and portal vein hypoplasia consistent with Abernethy malformation type II. Conclusions: Abernethy malformation is rare in adults and was an incidental finding in this case. Although dermatological signs contributed to its detection, the relationship between the hemangioma and this condition, as well as its role as a potential physical sign, remains unclear.

| Abstract (Portuguese): | Antecedentes: las malformaciones de Abernethy son anomalías del desarrollo vascular con hipoplasia o agenesia de la vena porta que presentan una clínica variada debido a sus complicaciones o suelen diagnosticarse incidentalmente mediante exámenes de imagen, en su mayoría en edad pediátrica. Resumen del caso: se presenta el caso de una paciente de 39 años que acudió a consulta por telangiectasias aracniformes, y los exámenes de sangre revelaron pancitopenia y elevación de transaminasas hepáticas. Por la complejidad del caso, se descartaron enfermedades autoinmunes y trombosis de vena porta mediante un estudio de autoanticuerpos y ultrasonido Doppler. De manera incidental, la tomografía computarizada trifásica de abdomen reportó esplenomegalia, aneurisma de la arteria segmentaria inferior del riñón izquierdo, colaterales esplenorrenales e hipoplasia de la vena porta compatible con malformación de Abernethy tipo II. Conclusiones: la malformación de Abernethy es infrecuente en el adulto y en este caso fue un hallazgo incidental; aunque los signos dermatológicos aportaron a su detección, aún es poco clara la relación entre el hemangioma con esta patología y su participación como un posible signo físico.
